Running state power saving via reduced instructions per clock operation

摘要: A microprocessor includes functional units and control registers writeable to cause the institute actions that reduce instructions-per-clock rate of power consumption when is operating in its lowest performance running state. Examples include in-order vs. out-of-order execution, serial parallel cache access single multiple instruction issue, retire, translation and/or formatting per clock cycle. The may be instituted only if additional conditions exist, such as residing state for a minimum time, not higher more than maximum user did disable feature, supports states system states.
