MICROPROCESSOR SYSTEM

摘要

PURPOSE: A microprocessor system is provided to efficiently manage the energy/power consumption performance in a mobile environment and a ubiquitous environment by calculating an optimized DVFS level. CONSTITUTION: A microprocessor system includes an operating system(20) and a microprocessor(10). The operating system calculates a DVFS level, and the microprocessor controls an operating frequency or voltage according to the calculated DVFS level. The DVFS level calculation module(210) calculates the EDP or ED2P of the application program among the preset DVFS levels. The DVFS level calculation module selects the DVFS level of the minimum value.
