Based on Prospective Dynamic Frequency Scale Power Optimize Method for Multi-Cores Processor's I/O System

摘要

Power problem has been one of the most restricting development barriers of processor. I/O system power is an import part of the processor's power. The paper aims at I/O dynamic power of multi-cores processor, and put forwards a prospective dynamic frequency scale with clock gating power optimize method. The experimental results show that the method which we put forward can greatly reduce the dynamic power of I/O system.
