An autonomous decentralized low-power system with adaptive-universal control for a chip multi-processor

A technique for adaptive-universal control of clock frequency, supply voltage, and body bias optimizes the performance-to-power ratio of chip multi-processors. The technique is based on a compound built-in self-test and self-instructed look-up table scheme for an autonomous and decentralized system. Applied to a 32b ALU, power is reduced by seventy times.
