  • Abstract
    This work presents the design and the silicon implementation of an on-line energy optimizer unit, which is capable of dynamically adjusting power supply voltages and operating frequencies of multiple processing elements. The optimized voltage/frequency assignments are tailored to the instantaneous workload information and fully adaptive to variations in process and temperature. The optimizer unit has a fast response time of 50 mus, occupies a silicon area of 0.021mm2 / task and dissipates 2 mW/task
