Xilinx is tackling two of the key barriers to using FPGAs - power and cost. It is reducing the power consumption of its new 7 Series devices families by 50% over the previous generation and has developed an architecture that wil scale across three families, helping to reduce costs. However, the idea of heading into mobile equipment with some of these parts is somewhat optimisitic - low power serves more purpose in increasing channel density in networking and telecoms applications.
“The 7 series represents a new juncture for Xilinx, and the FPGA industry in general, as we bring our technology portfolio to new markets by putting a significant emphasis on lowering power consumption,” said Xilinx President and CEO Moshe Gavrielov. “In addition to delivering what we and our customers expect from Moore’s Law in terms of capacity and performance with each new generation, we continue our focus on opening programmable logic to a broader audience by delivering design platforms targeted toward the specific needs of new users and markets.”The low static power comes from a HKMG (high-K metal gate) process optimized for low static power consumption (see “Xilinx Picks 28nm High-Performance, Low-Power Process to Accelerate Platforms for Driving the Programmable Imperative”) that lowers static power consumption by 50 percent compared to the alternative 28nm high-performance process. Xilinx then applied architectural enhancements to lower dynamic power consumption both for logic and I/O, while also introducing intelligent clock-gating technology with the release of ISE Design Suite 12. The result is an FPGA series that provides 50 percent lower total power consumption compared to Virtex-6 and Spartan-6 FPGAs and 30 percent lower than alternative 28nm FPGA device families.
Designers can take full advantage of up to 4.7TMACS in DSP performance symmetric mode (2.37TMACs in non-symmetric mode) and 2 million logic cells at clock speeds of up to 600MHz, and achieve up to 2.4Tbps high-speed connectivity all while staying within their power budgets.
All 7 series FPGAs share a unified architecture that enables customers to easily scale their designs up or down in capability to reduce cost and power or increase performance and capability, thereby reducing their investment in developing and deploying products across low-cost and high-performance families. The architecture is derived from the widely successful Virtex-series-based architecture and has been designed to simplify reuse of current Virtex-6 and Spartan-6 FPGA designs. It is also supported by the EasyPath FPGA cost reduction solution for the move to fixed silicon that further improves productivity by enabling a guaranteed 35 percent cost reduction with no incremental conversion or engineering investment.
Customers who need the lower power or increased system performance and capacity provided in the new 7 series FPGAs can begin designs in Virtex-6 and Spartan-6 FPGAs and move the designs when the time is right through the adoption of the AMBA AXI interconnect standard enabling plug-and-play IP usage to help customers improve productivity and development costs.
“Integrating 6-LUT architecture and working with ARM on the AMBA specification for these devices supports IP reuse, portability, and predictability,” said Andy Norton, CTO for Systems Architecture, Cloudshield Technologies, an SAIC company. “A unified architecture, new paradigm-changing processor-centric devices and hierarchical-based design flows in next-gen tools, will result in increased productivity, flexibility, system-on-chip capabilities and portability from previous generation architectures.”
The devices use the same logic architecture, Block RAM, clocking technology, DSP slices, and SelectIO™ technology and build on previous generations of devices delivered by Xilinx’s patented Virtex series ASMBL block architecture. This next generation ASMBL architecture provides unprecedented flexibility and scalability that enables customers to most effectively use the full range of logic densities.
Xilinx 7 Series FPGA Families:
Virtex-7 Family: 2X system performance improvement at 50 percent lower power compared to Virtex-6 devices, the ultra high-end Virtex-7 family sets new industry benchmarks with 1.8X greater signal processing performance, 1.6x greater I/O bandwidth, 2X greater memory bandwidth with 2133 Mbps memory interfacing performance, and delivers the industry’s largest density FPGA with 2 million logic cells, which is 2.5X greater density than any previous or existing FPGA. EasyPath-7 devices are also available for all Virtex-7 FPGAs for a guaranteed 35% cost reduction without requiring any design conversion. Virtex-7 devices enable 400G bridging and switch fabric wired communication systems that are at the heart of the global wired infrastructure, advance RADAR systems, and high-performance computer systems that require single-chip TeraMACC signal processing capabilities, as well as the logic density, performance, and I/O bandwidth required for next generation test and measurement equipment. The Virtex-7 family will include “XT” extended capability devices with as many as 80 transceivers supporting individual line rates up to 13.1Gbps and devices that provide up to 1.9Tbps serial bandwidth. Also, these devices offer up to 850 SelectIO pins enabling the industry’s greatest number of parallel banks of 72-bit DDR3 memory interfaces supporting 2133Mbps. Future devices will also feature 28Gbps transceivers.
Kintex-7 Family: Establishing a new category of FPGAs, the Kintex-7 family delivers Virtex-6 family performance at less than half the price for a 2x price/performance improvement while consuming 50 percent less power. The family includes high-performance 10.3Gbps or lower-cost optimized 6.5Gbps serial connectivity, memory, and logic performance required for applications such as high volume 10G optical wired communication equipment. It also provides a balance of signal processing performance, power consumption, and cost to support the deployment of Long Term Evolution (LTE) wireless networks, meet the aggressive power and cost requirements required for next generation high definition 3D flat panel displays, and deliver the performance and bandwidth needed for next generation broadcast video-on-demand systems.
Artix-7 Family: Delivering 50 percent lower power and 35 percent lower cost compared to the Spartan-6 family, the Artix-7 family uses small form-factor packaging and the unified Virtex-series based architecture to deliver the performance required to address cost-sensitive, high-volume markets previously served by ASSPs, ASICs, and low-cost FPGAs. This new family meets low power performance requirements of battery-powered portable ultrasound equipment, and addresses small form factor, low power requirements for commercial digital camera lens control, as well as the strict size, weight, power, and cost (SWAPc) requirements for military avionics and communications equipment.
Early access ISE Design Suite software supporting 7 series FPGAs is now available. Initial devices will be available in Q1 of next year.

Strong demand for power management semiconductors in the first half of 2010 has caught suppliers off-guard, spurring shortages and causing prices to rise in the near term, says market researcher iSuppli. This will impact on the design and supply and cost of portable euipment in particular this year.
Revenue for power management semiconductors reached $6.9 billion in the first quarter of 2010, up 2.9 percent from $6.7 billion in the fourth quarter of 2009. Sequential growth in the first quarter is remarkable given that it is weakest period of the year for sales of semiconductors. The growth of the first quarter reflects a continuation of the expansion that started during the last three months of 2009, after the market stalled briefly in the third quarter of last year.
Growth is expected to continue in the second quarter this year, when revenue is set to rise another 7.2 percent to hit $7.4 billion. And although a bigger upward movement occurred during the same time last year—when power management ascended 18.2 percent from $4.4 billion to $5.2 billion—the second quarter in 2010 will deliver the most robust growth for the industry this year.
“The expansion in the first quarter of 2010 took place because of the industry’s move to fulfill order backlogs and to satisfy limited demand, both of which shrank in the wake of the economic slowdown last year,” said Marijana Vukicevic, principal analyst for power management at iSuppli. “In contrast, growth in the second quarter will be fueled by increased activity in a number of areas utilizing power management semiconductors, including consumer electronics, wireless communications and data processing.”
Suppliers beset with shortages; prices to rise
Suppliers now are suffering from a shortage of power semiconductors, mainly because a recovery in demand—which started in the fourth of quarter of last year—has proven to be of a greater magnitude than current operational capacity can handle. Even with the rehiring of workers and the reopening of fab lines, suppliers have been caught off-guard by the resurgent demand and are unable to keep up, iSuppli’s findings show.
Furthermore, inventory levels at distributors decreased by 1.5 days in the fourth quarter of 2009 amid strong sales—a development that induced even more demand, especially for the analogue and discrete components of the market that already were in a state of shortage. The decline in inventory not only will contribute to big delays at the back end, particularly for analog suppliers, but also will serve to increase pricing, iSuppli believes.
And while prices are expected to stabilize in the second half of 2010, the shortage of commodity devices is likely to drive up Average Selling Prices (ASPs) in the first half, affecting buyers in the short term. Essentially, the price increases will persist until supply catches up with demand, iSuppli projections indicate.

Mercury Computer Systems has started shipping the industry’s highest performance 6U module-based OpenVPX, dual GPU-based conduction-cooled subsystem, using whichever high power GPU is available. This subsystem is currently deployed in an embedded rugged defense surveillance platform, performing processing, exploitation, and dissemination (PED).
One of the toughest challenges is to improve the military situational awareness through timely and precise delivery of actionable information by improved PED capabilities. Mercury’s subsystems are designed to provide these Embedded Smart Processing capabilities, enabling sensors to be smarter, able to accept unrelenting streams of data, and extract and deliver situational awareness and other crucial information.
Mercury’s scalable ISR subsystem is powered by the Ensemble 6000 Series GSC6200 – an OpenVPX module powered by GPU technology working in conjunction with Intel-based processing in a conduction-cooled, 6U form factor. The subsystem currently delivers performance in the TeraFLOPS range, and the incorporation of GPUs enables the solution to be delivered in an optimized size, weight, and power (SWaP) footprint. Mercury’s innovative packaging technology on the GSC6200 leverages the easy-to-upgrade MxM GPU form factor, which enables customers to rapidly upgrade and deploy the latest and fastest GPUs from ATI or NVIDIA, resulting in even higher performance.
“Our services and systems integration expertise allows us to offer our latest technology in a subsystem solution. This allows our customers to reduce their development risk while enabling concurrent engineering, ultimately leading to increased product velocity. Also, our approach of using standards-based, open APIs results in a subsystem which is open, a key requirement of our customers and as well as the U.S. Department of Defense,” said Steve Patterson, Vice President of Defense Product Line Management at Mercury.
“Mercury’s new OpenVPX GSC6200 module leverages the best available technologies while providing a clear migration path for customers to implement emerging GPUs from either ATI or NVIDIA in the future. This enables our customers to offer best of breed solutions for the industry’s most demanding high-end signal and image processing applications,” he added.
In addition to the GSC6200, other critical modules and services enabled the successful production of this subsystem. Mercury’s Services and Systems Integration team combined a multi-vendor hardware and software approach with their expert integration services to create the subsystem. The GSC6200 is providing industry-leading processing and exploitation capabilities to enable substantial SWaP improvements and parallel stream computing capabilities.

Print heads still drive MEMS manufacturing but cell phone accelerometers are catching up

It's always good to have pre-conceptions challenged, and this one is big - that HP is the leading manufacturer of Microelectromechanical (MEMS) sensors among semiconductor Integrated Device Manufacturers (IDM) and fabless firms, according to the latest figures from market researchers iSuppli.
“While sales of Hewlett-Packard’s inkjet printers fell 12 percent in 2009, the top player was able to cushion the blow through its large installed base, whose use of disposable printheads or replacement ink cartridges continues to provide significant revenues,” said Jérémie Bouchaud, principal analyst at iSuppli. “More than half of Hewlett-Packard’s MEMS revenue is fabless, and the company outsources the fabrication of a large portion of its printheads to STMicroelectronics. The seismic-grade accelerometers introduced by the company at the end of 2009 have not yet started contributing to its MEMS revenue, iSuppli research shows.”
In second place and mirroring its runner-up position in 2008 was Texas Instruments.
“Despite losing several hundred million dollars in MEMS since 2006, Texas Instruments benefited in 2009 from the revenue that MEMS in pico-projectors started to bring in,” Bouchaud said. “Furthermore, the MEMS in DLP chipsets produced by Texas Instruments for use in rear-projection TVs did better than expected, thanks to Mitsubishi Corp.’s continuing investment in laser rear-projection technology utilizing DLP.”
Likewise unchanged in their 2009 positions from the year before were the companies in third and fourth place: Bosch and Canon. Bosch, at No. 3, saw its overall MEMS revenue dip by 3 percent and its automotive MEMS revenue decline by 17 percent. However, consumer electronics revenue from the company’s Bosch Sensortec branch rose almost fourfold last year. Holding down the No. 4 spot was Canon, which gained MEMS share in the inkjet printhead segment, although its shipments remained flat.
Other companies in the IDM and fabless category that performed well included Epson, which achieved a 12 percent increase in revenue thanks to its booming quartz MEMS gyroscope business; and STMicroelectronics, which holds more than 40 percent of the accelerometer market for cell phones.
IDMs—i.e., semiconductor suppliers that conduct their manufacturing in-house—accounted for a greater share of MEMS revenue—roughly 77 percent, compared 23 percent for fabless manufacturers. However, the market share of fabless firms—i.e., semiconductor companies that outsource their manufacturing—is set to increase during the next five years because of the growing trend in the industry to use external foundries for semiconductor production.
Taken together, MEMS revenue for the Top 10 IDMs and fabless manufacturers amounted to $5.7 billion in 2009, down 8.8 percent from the year before. The decline was less than expected, mainly because of the impressive recovery of sensor production, especially in the automotive sector, during the last four months of 2009.

A team of Duke University chemists has perfected a simple way to make tiny copper nanowires in quantity that are small enough to be transparent, making them ideal for thin-film solar cells, flat-screen TVs and computers, and flexible displays.
"Imagine a foldable iPad," said Benjamin Wiley, an assistant professor of chemistry at Duke. His team reports its findings online this week in Advanced Materials.
Nanowires made of copper perform better than carbon nanotubes, and are much cheaper than silver nanowires, Wiley said.
“If we are going to have these ubiquitous electronics and solar cells,” Wiley said, “we need to use materials that are abundant in the earth’s crust and don’t take much energy to extract.” He points out that there are very few materials that are known to be both transparent and conductive, which is why ITO (indium tin oxide) is still being used despite its drawbacks, particularly being brittle.
However, Wiley’s new work shows that copper, which is a thousand times more abundant than indium, can be used to make a film of nanowires that is both transparent and conductive.
Silver nanowires also perform well as a transparent conductor, and Wiley contributed to a patent on the production of them as a graduate student. But silver, like indium, is rare and expensive. Other researchers have been trying to improve the performance of carbon nanotubes as a transparent conductor, but without much luck.
“The fact that copper nanowires are cheaper and work better makes them a very promising material to solve this problem,” Wiley said.
Wiley and his students, PhD candidate Aaron Rathmell and undergraduate Stephen Bergin, grew the copper nanowires in a water-based solution. “By adding different chemicals to the solution, you can control the assembly of atoms into different nanostructures,” Wiley said. In this case, when the copper crystallizes, it first forms tiny “seeds,” and then a single nanowire sprouts from each seed. It’s a mechanism of crystal growth that has never been observed before.
Because the process is water-based, and because copper nanowires are flexible, Wiley thinks the nanowires could be coated from solution in a roll-to-roll process, like newspaper printing, which would be much more efficient than the ITO production process.
Wiley’s lab is also the first to demonstrate that copper nanowires perform well as a transparent conductor. He said the process will need to be scaled up for commercial use, and he’s got a couple of other problems to solve as well: preventing the nanowires from clumping, which reduces transparency, and preventing the copper from oxidizing, which decreases conductivity. Once the clumping problem has been worked out, Wiley believes the conductivity of the copper nanowires will match that of silver nanowires and ITO.
Wiley, who has applied for a patent for his process, expects to see copper nanowires in commercial use in the not-too-distant future. He notes that there is already investment financing available for the development of transparent conductors based on silver nanowires.“We think that using a material that is a hundred times cheaper will be even more attractive to venture capitalists, electronic companies and solar companies who all need these transparent electrodes,” he said.

“We are excited to announce this radically differentiated server technology platform,” said Dr. Eng Lim Goh, senior vice president and chief technology officer at SGI. “Our innovative technology will enable users to attain new levels of scalability and speed with groundbreaking performance capabilities, culminating in a petaflop in a cabinet.”The new platform was designed to drive performance to specifically address the growing science and engineering technical markets that rely on high-end software to achieve rapid results. It offers GPU processing capabilities from NVIDIA and ATI, as well as accelerator-based technology from Tilera, and other peripheral component interconnect express (PCIe) based solutions. The technology will be seen in SGI products by the end of 2010.
“SGI shows its R&D strength again,” said Steve Conway, IDC research vice president for high performance computing. “Following closely on the heels of the Altix UV series, SGI has introduced a highly dense, scalable technology designed for strong sustained performance on very demanding HPC applications.”
