Cover Story: Design Tips Cut FPGA Power Use
July 24, 2008 12:10 pm | Articles | CommentsOverall, the latest generations of FPGAs provide the performance engineers need for new designs. And FPGA vendors complement performance with power-saving techniques. In many cases, FPGA design tools consistently aim to implement low-power circuits, but engineers can select performance vs. power tradeoffs as well. Most of those low-power changes occur within the design tools and do not cause engineers to rework their code. But before anyone tries to reduce power, they must understand where the power gets burned. It makes no sense to reduce power consumption in an area that doesn’t burn that much power to begin with.
