A distinguishing attribute to the Chumby is its very open hardware/software environment. By making details available on all the inner workings, Chumby Industries actively encourages users to hack the device and develop new uses for the platform. While many electronic devices have their own supporting software development kit (SDK) environment for third parties, few are as open as the Chumby's, which provides access to everything from the hardware schematics to an open-source Linux-based software client.

Many soft&#45switching techniques have been introduced for higher efficiency by reducing power losses during the on/off transition of power switches. For an example, a LLC resonant topology is now a mainstream topology for flat panel TV power supplies, and telecom power supplies and even for high&#45end game console power supplies. For the secondary&#45side of switch&#45mode power supplies, a synchronous rectifier becomes an essential building block for greater efficiency and higher power density. It replaces rectifiers in terms of providing better efficiency. Power losses can be lowered when the product of MOSFET's on resistance and drain current is less than the diode forward voltage drop. It is very popular in applications ranging from high&#45end servers to laptop adapters. This synchronous rectification is even used in desktop PC power supplies that never have been considered as high&#45end” applications. These applications are often referred to as 'silverbox' application because their outer housing is made of silver colored steel, and a cost is everything to them. But, things are changing after the 80 PLUS guideline has introduced. This guideline suggests over 80% of efficiency at 20%, 50%, and 100% load conditions. The synchronous rectifier was not considered though because it increases not only efficiency, but cost. Now, the guideline is moving towards a higher level. With new 85 PLUS guideline or higher, both soft&#45switching topology and synchronous rectification are required to make the switch&#45mode power supplies meet this target efficiency level. This stringent guideline also forces silverbox design to be changed to single 12V output with local DC&#45DC converters for 5V and 3.3V outputs.

The Spartan-6 FPGA architecture builds on the success of the Virtex-5 family, but emphasizes lower cost and lower power consumption, using a mature 45-nm process.

Editor's note: Over the past year and a half, Programmable Logic DesignLine has published several lite” user guides detailing the use of products from Xilinx Inc. and Altera Corp. These have been extremely popular. That should come as no surprise when you consider their purpose (which by now you probably know by heart): to provide users with significantly more details about the devices' functionality than can be found in a product datasheet without delving into the minutia provided by the full, comprehensive product user guides.
