Silicon carbide ready for prime time Product News 2/25/2008 2 comments NASA thinks silicon carbide is ready to replace silicon in circuitry that must withstand ultrahot temperatures--as high as 1,000 degrees F--or deliver ultrahigh power.
Researchers measure force to move a single atom News & Analysis 2/22/2008 Post a comment Researchers at the University of Regensburg in Germany and IBM's Almaden Research Labs in California have calculated for the first time exactly how much effort is needed to drag a single atom of cobalt across the surface of different metals.
Analog's answer to FPGA opens field to masses News & Analysis 2/21/2008 Post a comment By making analog circuits easier to design and simulate, researchers at the Georgia Institute of Technology hope to further the cause of analog while enabling engineers to incorporate lower-power circuitry into their products. In the same way that field- programmable gate arrays have spawned advances in digital signal processing, the Georgia Tech researchers believe their large-scale field-programmable analog array (FPAA) has the potential to seed growth in analog.
Lego Mindstorm gymnastic robot is flipping great News & Analysis 2/20/2008 Post a comment Students in Taipei used Lego MindStorm NXT to build a two-link gymnastic robot which can perform giant loops on a horizontal bar. The hand-and-bar link is a free-running passive joint. Two NXT motors are used to drive the robot-shoulder link. The students were seeking the factors to make repeatable and predictable loops although there is a suspicion of non-linear chaotic behavior in the two-motor system.

Under the Hood: When is a chip not a chip? Teardown 2/14/2008 1 comment There are many reasons why a semiconductor component might be branded with markings that differ from those of its actual manufacturer. A case in point is the Apple iPhone, which includes multiple devices from large companies (such as Broadcom, Philips, Samsung and Texas Instruments); all the devices carry Apple package markings.
Xilinx Virtex-5 User-Guide Lite Design How-To 2/13/2008 5 comments As opposed to wading through more than 1,000 pages of Virtex-5 User-Guide documentation, this "User Guide Lite " boils all the key details down into a few easily-digestible pages.
Pickled onions that bite back Programmable Logic DesignLine Blog 2/12/2008 Post a comment I recently received an email from someone who had tried one of my recipes with some success, so I thought I'd share this little scamp...
Blog Doing Math in FPGAs Tom Burke 24 comments For a recent project, I explored doing "real" (that is, non-integer) math on a Spartan 3 FPGA. FPGAs, by their nature, do integer math. That is, there's no floating-point ...
