Abstract :
An energy-saving system for SOCs using multiple threshold voltage CMOS was developed. It equips process sensors and process-voltage conversion table generated from static timing analysis results, and adjusts. The supply voltage according to die-to-die process variation. We applied this system to an embedded dual-core microprocessor using 90nm triple Threshold voltage CMOS technology. When the microprocessor executes video stream decoding program, 17% power reduction was measured with dies of typical process condition
