New Study Calls for World-Wide Reduction in Energy Consumption
July 3, 2008 8:42 am | by Jason Lomberg | Blogs | CommentsA Swiss Academic Study, “The 2000 Watt Society,” is gaining a lot of traction in the environmental movement. First developed by researchers at the Swiss Federal Institute of Technology, the latest treatise ("Smarter Living") was coordinated by Novatlantis, and is an urgent call to action. In short, it proposes an overall reduction in energy consumption to the world-wide average of 2,000 watts per capita by the year 2050. Naturally, the US bears the brunt of the scorn.

SMH: Wringing the Power Consumption Out of That FPGA
July 2, 2008 11:24 am | Articles | CommentsComputationally intensive DSP functions often require hardware acceleration. Increasingly, designers are implementing their DSP algorithms in FPGAs because they offer better performance than DSP processors. Benchmarks show that FPGAs execute turbocoding, GPS correlation, H264 and other DSP functions much more quickly than DSPs.
