We propose three methods for reducing power consumption in high-performance FPGAs (field programmable gate arrays). We show that by using continuous hierarchy memory, lightweight checks, and lower chip voltage for near-threshold voltage computation, we can both reduce power consumption and increase reliability without a decrease in throughput. We have implemented these techniques in two different, realistic wide-area motion imagery algorithms on FPGAs. We demonstrated greatly improved performance/efficiency compared to two flight-tested platforms, getting up to a 250X reduction in power use (measured in giga operations per second per watt). This paper summarizes these two case studies.
