HIGH ENERGY EFFICIENCY PROCESSOR USING DYNAMIC VOLTAGE SCALING

摘要

A high energy efficiency processor applying DVS is provided to maximize energy efficiency represented as 'performance/total power consumption' by using a simple structure, support a parallel processing architecture by using a plurality of processors, and realize a parallel processor including the plurality of processing elements performing parallel processing. A function unit block(200) performs operation according to an instruction received from an instruction register(110). Each parallel unit block(400) communicates data with an external device. An instruction interpreter(120) interprets the received instruction, and determines an operation mode of the function and parallel unit block required for executing the interpreted instruction. A function unit block operator(300) applies a different voltage level from the operation mode of the function unit block. A parallel unit block operator(500) applies the different voltage level from the operation mode of the parallel unit block. The function unit block includes more than two function units and more than two function unit operators for applying the different voltage level by control of the instruction interpreter.
