Xilinx's Virtex-7 2000T FPGAs
Editor's Note
Intel has proclaimed this week the fortieth anniversary of the microprocessor. For a 40-year-old, it is holding up quite well, thank you, if other news this week is to be believed.
On the X86 front, Intel rolled out two 6-core Sandy Bridge CPUs and unveiled the 50-core X86 Knight's Corner coprocessor. Not to be outdone, AMD launched its 4- to 16-core Opteron 5670 and 6276 X86 processors. ARM, the X86's nemesis in the embedded market, also showed off its alternative architecture muscle by announcing an 8-way ARM graphics core, and Arm-licensee Nvidia is working on an ARM-based supercomputer for the Spanish. And TI showed its supercomputing capabilities with low power 160 to 512 GFLOPS performance on the Keystone x66 DSP architecture. Also, LSI and Fujitsu said they are working on a Sparc-based multicore processor for supercomputing.
In “Xilinx's Virtex-7 200T FPGAs ,” Jack Ganssle provides his impressions of the new FPGA architecture. Other recommended embedded commentary this week includes “Moving toward an open standard for M2M development,” by Susan Rambo, “What's worse: incorrect documentation or none?” by Bill Schweber, and “Interference – cost tradeoffs and cheating” by Doug Grant.
If you are a fan of good tech videos watch “New Microchip PIC32MX1-2 starter kit up close and personal , ” featuring Chris Ciufo, Director of Content (Embedded), and “Microchip CLC Demo at ESC Boston , ” in which he talks to Microchip's Fanie Duvenhage about the use on PIC MCUs of a new configurable logic cell (CLC) feature.

Understanding electromagnetic interference sources in touchscreens
Vadim Konradi of Silicon Labs reviews the various EMI problems associated with projected-capacitance touchscreens in today's portable devices. The author then outlines design and optimization techniques to deal with the interference coupling paths.
Use Smart Services to take advantage of M2M connectivity
In this Product How-To article, Kevin Rhoads of Kontron explains benefits of using the company's M2M Smart Services Developer Kit to accelerate the creation of wireless smart services applications and provide a pre-validated platform for M2M software.
Web services puts M2M in The Cloud
Web services are one way to connect devices and sensors to the extended Internet, where objects talk to other objects. Here's a primer on how Web services work for machine-to-machine applications.
Design capacitive touch systems for robustness and manufacturability
In this Product How-To design article, Jean Viljoen of Azoteq, details the EMI and other challenges of designing capacitive touch user interfaces and how to use the company's ProxSense auto tuning technology to negate the need for calibration.
Understanding the security framework behind RSA SecurID
This article takes you through the two-factor authentication-base RSA SecurID security protocol – not to be confused with the RSA public key cryptographic mechanism – and how to use it for providing secure remote access for a user to a network resource as well as some potential vulnerabilities to guard against.
Add graphics without using a dedicated graphics controller
The author describes the various means by which integrated peripherals on a microcontroller along with graphics libraries enable embedded designers to push down costs by driving an LCD display without a graphics controller.
Combine power feed and data link via cable for remote peripherals
It is possible to combine power distribution and high-speed data transmission by sharing a shielded twisted pair cable. A power feed network is necessary at both ends for power injection and extraction. By properly designing this network, and managing power supply switching noise, performance degradation is minimized.
Energy harvesting and renewable energy sources
Energy harvesting is hot, and the Power Solutions: Smart Energy Technologies and Techniques Virtual Event by EETimes will address major issues associated with the design and integration of solar- and wind-harvesting systems.
How to know if your SSD will go the distance
Increased adoption of data-intensive applications is driving a move to high-performance SSDs in enterprise data centers. But the focus on speed has overshadowed concerns about SSD endurance. Emerging technology enhancements can mitigate these issues.
