Description
Summary:This paper discusses the performance benefits and energy efficiency improvements from microprocessors that communicate with their power supply. The power supply's response to computing load changes can be vastly improved with information about expected transients. Supply voltages can be modified to decrease steady-state power losses. A microprocessor can also adjust its computational activity based on information provided by the power supply. Additional benefits such as cost reduction, size reduction, and improved reliability are expected. Experimental results demonstrate the benefits.
