An energy-saving technique for SOCs using multiple threshold voltage CMOS was developed. It uses process sensors and process-voltage conversion tables generated from static timing analysis results to adjust the supply voltage according to process variation. A critical path replica circuit is conventionally used to determine a supply voltage. We enabled a supply voltage adjustment according to the process variation for SOCs using multiple threshold voltage CMOS by separating the path delay into a technology dependence part and a design dependence part. We applied this system to an embedded dual-core microprocessor using 90nm triple threshold voltage CMOS technology. When the microprocessor executes a video stream decoding program, 33% power reduction was measured with dies of fast process condition. |
