Samsung prototypes flexible quantum dot display

Transfer printing for 4in display using quantum dots

By Nick Flaherty www.flaherty.co.uk

In what may well turn out to be a key development in displays, Samsung and the University of Cambridge have developed a small prototype display using quantum dots that are transfer printed onto a  substrate. 
Light-emitting diodes with quantum dot luminophores demonstrate high quantum yields, extremely narrow emission, spectral tunability and high stability, among other beneficial characteristics, but up until now the inability to achieve size-selective quantum dot patterning by conventional methods has hindered the development of full-colour quantum dot displays. 
The researchers have demonstrated a large-area, full-colour quantum dot display, including in flexible form, using optimized quantum dot films, and with control of the nano-interfaces and carrier behaviour. The printed quantum dot films exhibit excellent morphology, well-ordered quantum dot structure and clearly defined interfaces and have been produced through the solvent-free transfer of quantum dot films and the compact structure of the quantum dot networks. 
The results suggest routes towards creating large-scale optoelectronic devices in displays, solid-state lighting and photovoltaics, say the team.

Embedded Vision Alliance forms to drive machine vision

Industry leaders unite on “machines that see”
By Nick Flaherty www.flaherty.co.uk

More than fifteen leading technology companies— including some of the largest semiconductor companies—have joined forces to speed the adoption of computer vision capabilities in electronic products. 
 The ability of machines to see and understand their environments - embedded vision - promises to transform the electronics industry with products that are more intelligent and aware of their environments, and to create significant new markets for electronic equipment and components. The Embedded Vision Alliance (www.embedded-vision.com), aims to enable the proliferation of embedded vision technology by providing design engineers with information, practical know-how, and industry standards.
“Adding computer vision to embedded systems creates phenomenal new products, markets, and opportunities,” said Jeff Bier, president of embedded analysts BDTI. “Just look at the Microsoft Kinect, which added vision to the Xbox 360—it became the fastest-selling consumer electronics device in history, shipping more than 10 million units in 5 months. But that’s just a small part of the story. From automobiles that prevent accidents to security cameras that prevent crimes, embedded vision will proliferate across a multitude of markets.”
BDTI, Xilinx, and IMS Research initiated the Embedded Vision Alliance (EVA) and are being joined by Analog Devices, Apical, Avnet Electronics Marketing, CEVA, CogniVue, Freescale, MathWorks, National Instruments, NVIDIA, Texas Instruments, Tokyo Electron Device, Ximea, and XMOS as founding members. These companies share the belief that incorporating vision capabilities into future products will bring dramatic benefits to users and provide high-growth opportunities in consumer, medical, automotive, entertainment, industrial, and retail markets.
“The momentum behind embedded vision applications is growing at an astounding rate and industry collaboration is needed to enable the technology’s smooth adoption in new markets,” said Vin Ratford, senior vice president of worldwide marketing and business development at Xilinx. “Xilinx is excited to be a founding member of the new Embedded Vision Alliance and looks forward to a long, successful partnership with the Alliance members. Through this collaboration—and by delivering the right combination of performance, price points and flexibility to intelligently manage and act upon vast amounts of real-time image data within the parameters of industry standards—our programmable platforms are poised to open up a new world for systems development.”
As a first step, the Embedded Vision Alliance is launching a website at www.embedded-vision.com. The site will serve as a source of practical information that will help design engineers incorporate vision capabilities in new systems. The EVA’s future plans include newsletters, educational webinars, industry reports, technology standards, and other related activities. Everyone is free to access the information on the website, which is maintained through member and industry contributions. Membership information is also available at the site.

Renesas pushes microcontrollers into LED lighting

Combines control, power and comms and expects to ship 1m units a month next year
By Nick Flaherty www.flaherty.co.uk

Renesas Electronics has launched a family of five 16bit single chip microcontrollers for the LED control, power supply control and communication functions required in LED lighting fixtures.
The RL78/I1A family addresses the need of a variety of lifestyles for lower cost, high-colour dimming and color temperature control and supports lighting communication standards for centralized control in buildings and offices. The new MCUs use the RL78 CPU core, which achieves both high computational performance and ultra low power consumption, and include from 32 to 64 kilobytes (KB) of flash memory in 20 to 38-pin package versions. These devices use 20% less power than the existing 78K0/Ix2 products.
Renesas is also launching evaluation boards, automatic software generation tools (Appilet EZ for HCD), a lighting fixture communication standard library, and other tools required for the development and evaluation of MCU software for lighting fixture applications in July.
LED lighting, which features low power consumption and long lifetimes, is the focus of attention as an effort to reduce CO2 emissions on a global scale. LED illumination is becoming increasingly widely used in industrial and commercial facilities, in streetlights, and in home lighting. The global market for LED lighting equipment is expected to grow rapidly from the roughly 20 million units sold in 2009 to over 400 million units in 2014.

Key features:

  • These new lighting MCUs provide six high-resolution PWM outputs that are capable of supporting an average resolution of 0.97 ns. This allows dimming and color temperature adjustments about 25 times more precise than RL78/Ix2 products. These new MCUs also include a new PWM output on/off control timer that allows them to support either current or PWM-based dimming adjustment. They also include a PGA (programmable gain amplifier) that can amplify the A/D converter input level by up to a factor of 32 to support high-precision LED current measurement. Not only does this make even finer-grained brightness adjustment possible, it also allows a smaller current measurement resistor to be used, thus contributing to reduced overall system power consumption.
  • A new PFC control function supports interleaved operation for in high-power equipment requiring improved power factors. As the internal comparators and an interrupt pin are internally interlocked with the PWM timers, this enables efficient PFC control without CPU involvement and eliminates the need for an external PFC control IC.
  • The new MCUs provide an overcurrent detection function that uses comparators (including window comparators that allow both upper and lower limits to be set) for overvoltage and overcurrent detection and stops PWM timer output automatically. This function can prevent breakdowns in lighting fixtures. The architecture allows different port output states when a forcible output stop occurs to be selected from three types: high-level output, low-level output, or high impedance, to support a wide range of protection circuits. The RL78/I1A MCUs support the IEC60730 European Home Appliance Safety Standard which is necessary for lighting fixtures by including; a FLASH memory CRC (cyclic redundancy check) calculation function, RAM parity error detection function, clock frequency detection function and illegal memory access prevention function.
  • In addition to CSI, these devices also support the I²C bus and UART (DMX512) standards and even the DALI (Digital Addressable Lighting Interface) open standard for lighting communication which also supports extended DALI frames so they can flexibly support lighting communication protocols.

Data sheet

Samples are available now, priced at US$2.50 per unit for the 38-pin, 64 KB flash memory, 4 KB RAM version. Mass production is scheduled to begin in January 2012 and is expected to reach a combined volume of 1,000,000 units per month in 2012.

TSMC to tape out 89 28nm designs

Targets 20nm designs using ARM Coretex processor cores

By Nick Flaherty www.flaherty.co.uk

TSMC's customers are taping out 89 new designs on its 28nm process using the Open Innovation Platform (OIP) design infrastructure. The company is also introducing OIP enhancements, including the delivery of Reference Flow 12.0 and Analogue/Mixed Signal (AMS) Reference Flow 2.0.
"TSMC customers can immediately take advantage of our 28nm advanced technology and manufacturing capacity while preparing for 20nm in the near future," said Cliff Hou, TSMC Senior Director for the Design and Technology Platform. "We have enabled customers to achieve their product design goals by closely collaborating with our EDA and IP partners to deliver a solid 28nm design ecosystem. In addition, the introduction of Reference Flow 12.0 and AMS Reference Flow 2.0 address critical design issues for the next generation of 28nm and 20nm applications."
TSMC's 28nm design ecosystem is ready today with foundation collateral such as DRC, LVS and PDKs; foundation IP, including standard cell libraries, standard I/O, eFuse and memory compilers; and standard interface IP such as USB, PCI and DDR/LPDDR. Customers can download these materials at TSMC Online. Collaboration with the EDA community for 28nm has been equally thorough in order to achieve tool consistency for improved design results. One example is a unified DFM engine for 28nm now in use by Cadence, Mentor and Synopsys.
Reference Flow 12.0 features various enhancements in: two-and-a-half dimensional and three dimensional integrated circuits (2.5-D/3-D ICs) using silicon interposer and through silicon via (TSV) technologies; 28nm model-based simulation DFM speed-up; and advanced Electronic System Level (ESL) design initiative enabling TSMC's process technology PPA (power, performance and area) to be integrated into system level design. In addition, Reference Flow 12.0 will disclose TSMC's 20nm Transparent Double Patterning design solution for the first time as part of the on-going build up of 20nm design capability within OIP.
AMS Reference Flow 2.0 offers an advanced multi-partner AMS design flow addressing the growing complexity of 28nm process effects and design challenges for superior DFM and RDR compliance and reliability.

Reference Flow 12.0 and Transparent Double Patterning for 20nm
20nm is the first process node where metal pitch is beyond the lithographic capabilities of existing exposure systems. Double patterning is the key enabling lithographic technology to overcome the litho resolution limitations without resorting to as yet production unproven technologies as EUV. TSMC's Transparent Double Patterning solution enables system and chip designers to access 20nm technology, implemented with double patterning, without any modifications to their current design methodologies or flows. This technology is being delivered to EDA partners and certified for delivery in their commercial products.

2.5D Silicon Interposer
Typically a 2.5D design includes multiple dies to be integrated with a silicon interposer, which is implemented in different technology. Reference Flow 12.0 features new design capabilities in floorplanning, P&R, and IR-drop and thermal analysis to accommodate multiple nodes simultaneously, as well as a new design for test methodology for 2.5D design.

28nm Power, Performance and DFM Design Enablement
Timing degradation from wire and via resistance becomes more significant in finer geometry technologies: Reference Flow 12.0 introduces an enhanced routing methodology to minimize via counts, change layers for routing, or widen wires to mitigate the impact of wire and via resistance.
Leakage current increases as threshold voltage and gate oxide thickness decrease in 28nm. Multi-Mode Multi-Corner (MMMC) leakage optimization accommodates different Vt options and gate-biased libraries enabling designers to more effectively reduce leakage.
Finally, in order to minimize the design cycle time of hotspot checking and fixing in 28nm, a new "hotspot filtering engine" is added to the DFM Data Kit (DDK) to speed up model-based DFM analysis.

AMS Reference Flow 2.0
AMS 2.0 helps designers to ensure the compliance of DFM and Restricted Design Rules (RDR) for custom design in 28nm. It demonstrates correct design configurations and options setting to use TSMC PDKs and DFM utilities. In addition, TSMC applies accumulated reliability lessons learned, and collaborates with ecosystem partners to introduce innovative approaches to filter out known potential reliability defects. TSMC and 21 OIP ecosystem partners will present and showcase the features and benefits of Reference Flow 12.0 and AMS Reference Flow 2.0.

RF Reference Design Kit 3.0
For RF designers, TSMC will introduce a new RF Reference Design Kit (RF RDK 3.0) which includes an advanced, silicon correlated, 60GHz Millimeter Wave design kit, and an innovative way for customers to design with their own choice of inductors through EM (electromagnetic) simulation.

Boosting multicore performance

Two new techniques speed multicore performance by up to 40%

By Nick Flaherty www.flaherty.co.uk

Researchers from North Carolina State University have developed two new techniques to help maximize the performance of multi-core computer chips by allowing them to retrieve data more efficiently, which boosts chip performance by 10 to 40 percent.
To do this, the new techniques allow multi-core chips to deal with two things more efficiently: allocating bandwidth and “prefetching” data.
Multi-core chips are supposed to make our computers run faster. Each core on a chip is its own central processing unit, or computer brain. However, there are things that can slow these cores. For example, each core needs to retrieve data from memory that is not stored on its chip. There is a limited pathway – or bandwidth – these cores can use to retrieve that off-chip data. As chips have incorporated more and more cores, the bandwidth has become increasingly congested – slowing down system performance.
One of the ways to increase the core performance is prefetching. Each chip has its own cache and with prefetching, the cache predicts what data a core will need in the future and retrieves that data from off-chip memory before the core needs it. Ideally, this improves the core’s performance. But if the cache’s prediction is inaccurate, it unnecessarily clogs the bandwidth while retrieving the wrong data. This actually slows the chip’s overall performance.
“The first technique relies on criteria we developed to determine how much bandwidth should be allotted to each core on a chip,” says Dr. Yan Solihin, associate professor of electrical and computer engineering at NC State and co-author of a paper describing the research. Some cores require more off-chip data than others. The researchers use easily-collected data from the hardware counters on each chip to determine which cores need more bandwidth. “By better distributing the bandwidth to the appropriate cores, the criteria are able to maximize system performance,” Solihin says.
“The second technique relies on a set of criteria we developed for determining when prefetching will boost performance and should be utilized,” Solihin says, “as well as when prefetching would slow things down and should be avoided.” These criteria also use data from each chip’s hardware counters. The prefetching criteria would allow manufacturers to make multi-core chips that operate more efficiently, because each of the individual cores would automatically turn prefetching on or off as needed.
Using both sets of criteria, the researchers were able to boost multi-core chip performance by 40 percent, compared to multi-core chips that do not prefetch data, and by 10 percent over multi-core chips that always prefetch data.
The paper, “Studying the Impact of Hardware Prefetching and Bandwidth Partitioning in Chip-Multiprocessors,” will be presented on June 9th at the International Conference on Measurement and Modeling of Computer Systems (SIGMETRICS) in San Jose, Calif. The paper was co-authored by Dr. Fang Liu, a former Ph.D. student at NC State.

Silicon Labs drives energy harvesting for wireless networks

Turnkey Energy Harvesting Reference Design 

By Nick Flaherty www.flaherty.co.uk


Silicon Labs has launched what it claims is the industry's most energy-efficient wireless sensor node solution powered by a solar energy harvesting source. A turnkey energy harvesting reference design enables developers to implement self-sustaining, ultra-low-power wireless sensor networks for home and building automation, security systems, industrial control applications, medical monitoring devices, asset tracking systems and infrastructure and agricultural monitoring systems.
The $45 reference design includes wireless network and USB software and a complete circuit design with RF layout, bill of materials (BOM), schematics and Gerber files. The design consists of three components:

  • A solar-powered wireless sensor node that measures temperature, light level and charge level, using an Si10xx wireless MCU to control the sensor system and transmit data wirelessly and a thin-film battery to store harvested energy.
  • A wireless USB adapter that connects the wireless sensor node to a PC for displaying sensor data; the adapter features Silicon Labs' Si4431 EZRadioPRO transceiver with an MCU running USB-HID class software and EZMac wireless software stack.
  • A wireless sensor network GUI that displays data from up to four sensor nodes.

The thin film battery used in the energy harvesting reference design has a capacity of 0.7 mAh. In direct sunlight, the battery can be recharged fully in only two hours. While in sleep mode, the wireless sensor node will retain a charge for 7,000 hours. If the wireless system is transmitting continuously, it will operate non-stop for about three hours, although it is designed to constantly recharge itself at an appropriate level to keep the thin-film battery from completely discharging.
The market for energy harvesting devices is poised to grow exponentially this decade. IDTechEx forecasts that more than ten billion energy harvesting devices will ship by 2019 - a 20x increase over the roughly 500 million units that shipped in 2009. Although systems powered by harvested energy sources have existed for many years, developers have been challenged to implement wireless sensor nodes within very low power budgets. Energy harvesting simplifies these applications by eliminating the inconvenience of replacing batteries in inaccessible locations, while also reducing the quantity of depleted batteries for recycling or dumped in landfills.
"As part of our global commitment to green technology, Silicon Labs has advanced the use of energy harvesting technology to free wireless networking systems from the cost, inconvenience and negative environmental impact of conventional batteries," said Mark Thompson, vice president of Silicon Labs' Embedded Mixed-Signal products. "By combining ultra-low-power wireless MCU technology with a state-of-the-art energy harvesting system, Silicon Labs has delivered the industry's most energy-efficient, self-sustaining wireless networking solution."
Silicon Labs' energy harvesting reference design accommodates a wide range of harvested energy sources. An on-board bypass connector gives developers the flexibility to bypass the solar cell and tap other energy harvesting sources such as vibration (piezoelectric), thermal and RF.

Ford develops heart monitor in car seats

By Nick Flaherty www.flaherty.co.uk

Ford engineers in Germany have developed a car seat that can monitor a driver’s heartbeat.
A joint project undertaken by experts from Ford’s European Research and Innovation Centre in Aachen, Germany and Rheinisch-Westfälische Technische Hochschule (RWTH) Aachen University, the seat uses six special embedded sensors to detect electrical impulses generated by the heart.
“Although currently still a research project, the heart rate monitor technology developed by Ford and RWTH Aachen University could prove to be a hugely important breakthrough for Ford drivers, and not just in terms of the ability to monitor the hearts of those known to be at risk,” said Dr Achim Lindner, Ford European Research and Innovation Centre medical officer. “As always in medicine, the earlier a condition is detected the easier it is to treat and this technology even has the potential to be instrumental in diagnosing conditions drivers were previously unaware they had.”
Ford developed the six-sensor system positioned on the surface of the seat backrest. The unobtrusive electrodes have been specially designed to be able to detect the electronic signature of the heart through clothing.
“The sensors use a very specially designed system and carefully researched materials to be able to give a good signal without contact on the skin,” said Lindner. “We are still fine-tuning their operation to work with some materials; certain types of synthetic fabric and lamb’s wool can cause electrical interference that upsets the signal, but we can achieve a strong signal through 10 layers of cotton.”
In stationary testing, 90 to 95 percent of subjects proved to be compatible and on-road testing of the Ford heart rate monitoring seat proved it was possible to achieve highly accurate readings for up to 98 percent of the time spent behind the wheel, even at this early stage of development.
Data collected by the sensors, for example, could be analyzed by medical experts or onboard computer software. Possibilities therefore abound, notes Lindner, from linking to remote medical services and Ford vehicle safety systems to even providing real-time health information and alerts of imminent cardiovascular issues such as a heart attack.
Ford is also researching how to use its SYNC technology and its ability to connect devices via Bluetooth, access cloud-based Internet services and control smartphone apps to develop voice-controlled in-car connections to health aids from glucose monitoring devices, diabetes management services, asthma management tools and Web-based allergen alert solutions.
The seat sensor technology under development could initially be of most benefit to drivers known to have heart conditions – primarily those in more mature age groups, a globally growing population.
“With increasing life expectancy meaning higher numbers of people and therefore drivers at risk of heart diseases, the ability to monitor hearts at the wheel could offer massive benefits in terms of health and road safety, both for the user and the wider public,” said RWTH Aachen University Professor Steffen Leonhardt, who originally proposed taking the university’s work with contactless infant heart monitoring to Ford. “The car is an obvious choice; it’s a place where occupants spend long periods sitting in a rather calm position and a place that’s increasingly less physically demanding, making it the ideal environment to measure heart activity.”

NetLogic starts volume production of IPv6 processors

New generation of IPv6 equipment from Tier One OEMs


By Nick Flaherty www.flaherty.co.uk

NetLogic Microsystems is shipping its NL11k family of IPv6 knowledge-based processors in volume for delivery to customers’ next generation of IPv6 switches and routers. The first of over two dozen IPv6 systems from leading original equipment manufacturers (OEMs) that are using the NL11k knowledge-based processors will begin shipping in production in the third quarter of 2011, with the remaining customer systems expected to commence shipping over the following twelve months.

“The emergence of LTE and IPv6 has dramatically increased the need for knowledge-based processors with significantly higher performance, larger database capacities and smaller thermal footprints. We are pleased to continue to lead the market in breakthrough innovations and product development excellence to bring to market six generations of best-in-class products.”
These new systems from Tier One OEMs are now being launched to support an increased level of IPv6 traffic with typical configurations now handling up to 33% native IPv6 traffic, which represent a major upgrade from previous generations of IPv4 equipment. To support IPv6’s 4x longer Internet addresses, as well as the exponential increase in the complexity and throughputs of network traffic, these new systems are adopting the most advanced knowledge-based processors from NetLogic Microsystems. This results in a more than doubling of the dollar content of knowledge-based processors per system over previous generations of equipment across every OEM customer.
In addition to these NL11k processor-based systems, Tier One OEMs are also designing with NetLogic Microsystems’ NL10k and NL82048 families of IPv6 knowledge-based processors into additional systems that will begin shipping throughout 2012. Moreover, these OEMs are expected to continue to upgrade their IPv6 equipment over their following successive generations of equipment to be able to support the ever increasing native IPv6 traffic in which is expected to continue to grow and become the substantial majority of traffic over time.
“We are excited by our volume production launch of the NL11k processors as it marks an important milestone in our next phase of growth for our knowledge-based processors into next-generation IPv6 equipment,” said Chris O’Reilly, vice president of marketing at NetLogic Microsystems. “The emergence of LTE and IPv6 has dramatically increased the need for knowledge-based processors with significantly higher performance, larger database capacities and smaller thermal footprints. We are pleased to continue to lead the market in breakthrough innovations and product development excellence to bring to market six generations of best-in-class products.”
The exhaustion of IPv4 Internet addresses, driven by the proliferation of connected mobile devices, is forcing service providers and network owners to migrate to the new IPv6 Internet addressing scheme which increases the number of available addresses by more than 28 orders of magnitude. According to the Wall Street Journal in a Feb. 1 article, a permanent shift to IPv6 is now inevitable following the Internet Assigned Numbers Authority’s (IANA) final allocation of its free pool of available IPv4 addresses.
Industry momentum in the migration to IPv6 continues to accelerate. On June 8th this year, Internet giants and service providers such as Google, Facebook, Yahoo, Comcast, Time Warner Cable and Akamai will offer and deliver their content over IPv6 in preparation for a successful transition as IPv4 addresses run out.
This migration to the longer IPv6 addresses, coupled with the exponential increase in the complexity and throughputs of network traffic, are driving an unprecedented need for knowledge-based processors with significantly higher performance and database capacity. To meet these stringent requirements, new knowledge-based processing architectures and circuit innovations such as those offered by the NL11k processor are needed to accelerate complex networking functions such as classification, security, routing/forwarding and deep-packet inspection.
 The NL11k processor family adopts a ground-breaking “hybrid” architecture that combines its best-in-class, massively parallel knowledge-based processing engines with the low-power efficiency and flexibility of its algorithmic Sahasra technology to reduce power consumption while delivering higher performance, capacity and scalability. The NL111024 knowledge-based processor, the flagship product in the NL11k family, delivers 1.6 billion decisions per second (BDPS), and integrates 128 high-performance knowledge-based processing engines, the Sahasra Algorithmic Engines (SAEs) and an enhanced Intelligent Load Balancing Engine (ILBE) to efficiently allocate multiple tasks and communicate among all the knowledge-based processing engines and SAEs.
The NL11k processor family also features the world’s first knowledge-based processors with high-speed serial interface that delivers 225 Gbps of raw chip-to-chip interconnect bandwidth. This represents a 340 percent increase in I/O bandwidth-per-pin to deliver an improved balance between the processing engines and the I/O performance to allow wider IPv6 keys to be processed at the same search rate as narrower IPv4 keys. This enables significantly higher system performance and system density for next-generation systems to enable significantly richer services for LTE and IPv6 equipment.
Manufactured in 40nm process technology, the NL11k knowledge-based processors also integrate an innovative Range Encoding Engine (REE), which employs advanced one-hot and fence encoding algorithms to implement range encoding that allows customers to effectively double the efficiency of performing port range inspection.

Redpine moves to 3x3 MIMO for HD video over WiFi

BEAM450 chipset includes MIMO ML decoding, transmit beamforming and simultaneous dual-band for 450Mbit/s throughput

By Nick Flaherty www.flaherty.co.uk

Redpine Signals has developed a family of highly integrated semiconductor products conforming to the 802.11n standard that are the first MIMO chips to support "software configurable simultaneous dual-band." This patent pending feature enables the system integrators to re-configure the MIMO chipset on-the-fly from a 3-Spatial Stream 450Mbps 3x3 system (working in either 2.4GHz or 5GHz ISM bands) into a simultaneous dual-band system with 150Mbps in one band and 300Mbps in the other band.
Simultaneous dual-band enables robust QoS provisioning for demanding video applications in crowded wireless environments, and the Maxi-Fi® BEAM450 provides this at zero cost and power overhead to the system. The new Maxi-Fi products include the RS9330 802.11n Baseband chip interfacing to either the RS8330 (Dual-band MIMO Radio chip) or the RS8331 (Dual-band MIMO Radio chip with built-in high power-amplifiers).
Redpine also provides TURBO900 and TURBO1350 reference designs, which use two or three RS9330 chips respectively. These designs provide physical layer throughputs of 900Mbps and 1.35Gbps on a "single" PCI-e host interface, thus addressing the performance requirements of today's most demanding wireless video applications.
With CMOS integration of a high performance MAC, baseband processor, analogue front-end, crystal oscillator, calibration EEPROM, balun, dual-band RF transceiver and dual-band high-power amplifiers (RS8331 only), the chips are targeting high throughput and high QoS wireless applications such as HD video streaming, storage devices, wireless routers, broadband access modems, televisions, access points, and set-top boxes. The chipset maintains over 300Mbps of TCP data throughput on various host platforms and runs on the 802.11n MAC on an SoC based on Redpine's proprietary four-threaded processor (ThreadArch) with very low-host overhead.

Digilent opens up Arduino with 32bit Microchip development boards

Dev Boards and Open-Source Software for protoyping and teaching

By Nick Flaherty www.flaherty.co.uk

Digilent has launched a development board for the popular open source Arduino microcontroller technology based around a 32bit chip from Microchip, reducing the cost of the boards and the end system.
This will open up more opportunities for prototyping, teaching in universities and hobbyists as well as other non-electronics applications. The recent USB typewriter (below), for example, was based on the Arduino platform.

Designed and manufactured by Digilent, the chipKIT platform enables hobbyists and academics to easily and cheaply integrate electronics into their projects, even if they do not have an electronic-engineering background. The platform consists of two PIC32-based development boards and open-source software that is compatible with the Arduino programming language and development environment, thanks to the work done by Mark Sproul and Rick Anderson through Fair Use Building and Research Labs
A key point is that the 32bit chipKIT hardware is compatible with existing 3.3V Arduino shields and applications, and can be developed using a modified version of the Arduino IDE and existing Arduino resources, such as code examples, libraries, references and tutorials. This means existing code can be easily dropped into the development system, with boards at $27 and $50.



The chipKIT boards use a PIC32 MIPS M4K processor running at 80MHz with up to 512KB Flash and 128KB RAM, as well as Ethernet, CAN, and USB (Full-Speed Host, Device and OTG); plus peripherals such as multiple timers, a 16-channel 1 MSPS Analogue-to-Digital Converter (ADC), two comparators, and multiple I2C, SPI, and UART interfaces. 
At the same time the Arduino programming environment has been modified and extended so that it supports the PIC32-based chipKIT boards, as well as traditional Arduino boards. The Arduino standard libraries have been also been modified to support chipKIT boards and traditional Arduino boards. All of this work has been contributed back to the open-source Arduino community. Aside from a small number of shields that require 5V operation, many existing Arduino hardware and software sketches are compatible with the chipKIT platform, without modification.
“Students, educators and hobbyists, with or without electronic-engineering backgrounds, are looking for inexpensive solutions that will enable them to easily integrate electronics into their projects,” said Derek Carlson, Microchip’s vice president of Development Systems. “The chipKIT boards and software meet these needs, providing far more features, performance and functionality than any other Arduino solution on the market, at a low cost.”
“The chipKIT platform is the first and only 32-bit solution of its kind in the industry,” said Clint Cole, president of Digilent. "Academics and hobbyists can plug the boards into their design, download the open-source software and have their project up and running in minutes.”
The chipKIT Uno32 (part # TDGL002) development board is a clone of the Arduino Uno board, and features 128 KB Flash program memory and 16 KB RAM, with two each of the I2C, SPI and UART peripherals. This board is priced at $26.95 each. 
 A clone of the Arduino Mega board, the chipKIT Max32 (part # TDGL003) development board features 512 KB Flash program memory and 128 KB RAM, with USB, CAN and Ethernet communication, as well as 5 each I2C, 4 each SPI, and 6 each UART peripherals. The chipKIT Max32 board is priced at $49.50 each. Both chipKIT boards can be ordered today, at http://www.microchip.com/get/TDD2. Additionally, the open-source software for both boards is available today at http://www.microchip.com/get/TDD2. chipKIT Network and I/O Shields are expected to be available in June 2011.

NXP demonstrates new 'car-to-anything' IEEE802.11p comms platform

Car-to-x (C2X) communication on a public road in Holland
By Nick Flaherty www.flaherty.co.uk

Dutch chip maker NXP Semiconductors has demonstrated car-to-x (C2X) communication on a public road in the Netherlands. With this demo, NXP is the first semiconductor company to take the step from showing concepts to actually demonstrating an automotive-ready hardware platform for connected mobility. 
NXP has co-developed the C2X platform with Australian-based Cohda Wireless to combine telematics for location-based services and networking security so that the car can communicate with kerb-side and wide area systems and other cars.
The C2X communication uses the IEEE802.11p wireless standard designed specifically for automotive applications. This allows cars to communicate with each other (car-to-car) as well as with intelligent traffic infrastructure (car-to-infrastructure) around them. The C2X platform from NXP and Cohda picks up information from other cars and static traffic systems so that drivers receive early warnings of cars hidden from sight behind trucks or approaching from around corners. Other use cases are warnings about emergency vehicles and traffic jams, or traffic light signals allowing drivers to adjust their speed and optimize driving.
The C2X platform is able to meet the requirements of the automotive industry: reliable signal reception for fast-moving objects even in difficult surroundings, cost-efficient design, and flexible programming. It uses Cohda’s 802.11p patented radio reception algorithms and is based on NXP’s multi-standard radio reception platform.
NXP is project leader of the Dutch SPITS research project (SPITS: Strategic Platform for Intelligent Transport Systems) and  is also demonstrating intelligent traffic data analysis from the in-vehicle networks, as well as emergency and breakdown calls based on NXP’s telematics module, ATOP.
“Connecting the car to the environment demands in-depth expertise in secure connectivity, Software-Defined Radio architectures, and telematics," said Kurt Sievers, senior vice president and general manager of the Automotive business at NXP Semiconductors. "The SPITS project has been extremely valuable for us as it brought experts and research partners from all parts of the value chain together all working towards the same goal: efficient and sustainable mobility solutions.”

About SPITS project

The Strategic Platform for Intelligent Transport Systems (SPITS) project has three main areas: traffic management and safety, concepts for open in-car platform, and downloadable services. SPITS was aimed at creating an open and affordable intelligent transport system platform, which is scalable, secure and real-time. The Dutch Ministry of Economic Affairs has subsidised the project. The consortium is lead by NXP Semiconductors and consists of eight companies (NXP, TomTom, TNO, Logica, Catena, Task24, Foutress, GreenCat), one research institute, and four universities. 
The SPITS system comprises the vehicle on-board unit (OBU), the Road Side Unit (RSU) infrastructure, and the Back Office (BO) service centre. Communications between these elements is a major part of the Strategic Platform. After the SPITS project officially ends, consortium members will continue to refine the SPITS results for commercial use across Europe and beyond. These projects represent an investment by the Government to retain key knowledge from R&D companies within the Netherlands, following the economic crisis.

World's smallest 3D printer

LED printer at just 1200 euros
By Nick Flaherty www.flaherty.co.uk

A research project at the Vienna University of Technology (TU Vienna) is aiming to could turn futuristic 3D-printers into affordable everyday items.
Printers which can produce three-dimensional objects have been available for years but the project has developed a much smaller, lighter and cheaper version that could be mass produced to brign down the cost. This would allow anyone to produce small, taylor-made 3D-objects at home, using building plans from the internet – and this could save money for expensive custom-built spare parts.
Several scientific fields have to come together to design the 3D-printer. The device was assembled by mechanical engineers in the research group of professor Jürgen Stampfl, but also the chemical research by the team of professor Robert Liska was of crucial importance: first, chemists have to determine which special kinds of synthetic material can be used for printing.
The basic principle of the 3D-printer is quite simple: The desired object is printed in a small tub filled with synthetic resin. The resin has a very special property: It hardens precisely where it is illuminated with intense beams of light. Layer for layer, the synthetic resin is irradiated at exactly the right spots and as one layer hardens, the next layer can be attached to it, until the object is completed in a process called 'additive manufacturing technology'. 
“This way, we can even produce complicated geometrical objects with an intricate inner structure, which could never be made using casting techniques,” said Klaus Stadlmann who developed the prototype together with Markus Hatzenbichler.
This method is not designed for large-scale production of bulk articles – for that, there are cheaper alternatives. The great advantage of additive manufacturing is the fact that is offers the possibility to produce bespoke individually adjusted items. The prototype of the printer is no bigger than a carton of milk, it weighs 1.5 kilograms, and at just 1200 Euros, it was remarkably cheap. “We will continue to reduce the size of the printer, and the price will definitely decrease too, if it is produced in large quantities”, Klaus Stadlmann believes.

LED for Higher Resolution
The individual layers hardened by the light beams are just a twentieth of a millimetre thick. Therefore, the printer can be used for applications which require extraordinary precision – such as construction parts for hearing aids. Unlike previous models, the printer at TU Vienna uses light emitting diodes (LEDs), with which high intensities of light can be obtained at very well-defined positions.
The research group for additive manufacturing technologies at TU Vienna is working with a variety of different 3D-techniques and materials. New materials – such as special ceramics or polymers – are constantly being developed for 3D-printing. 3D objects can now even be made from eco-friendly biodegradable substances. In cooperation with biologists and physicians, the scientists could show that the artificial structures created with their 3D-printer technology are perfectly suited to serve as a scaffold that supports natural growth of bone structure in the body.

Versatility

No matter whether it is medical parts, adjusted exactly to the patient’s needs, special spare parts which otherwise would have to be shipped around half the globe, or whether it is just some kind of self-designed bling jewellery: with the versatile and cheap devices and materials developed in Vienna, highly complex 3D objects can now be built from a variety of materials with very different mechanical, optical and thermal properties.
