The glitch that stole the FPGA's energy efficiency - Low-Power Design: The glitch that stole the FPGA's energy e...

Field-programmable gate arrays (FPGAs) are notorious for high power consumption. They are hard to power down in the same way as custom logic - so they have considerable static power consumption - and they use a lot more gates to achieve the same job with their greater flexibility. However, a good proportion of an FPGA's power consumption is avoidable. A 2007 study carried out by researchers at the University of British Columbia and published in IEEE Transactions on VLSI Systems found that up to three quarters of the dynamic power consumption could be ascribed to glitches rather than actual functional state transitions for some types of circuit. The heart of the problem lies with timing: early-arriving signals can drive outputs to the wrong state before the situation is 'corrected' by later signals and before the final state is ready for sampling at the next clock transitio...
