Based on the result of the wcet ( worst case execution time ) analysis, assisted with software such as the operating system or the compiler, real-time dynamic voltage scaling makes use of the dynamic variability of the execution time of a program, and effectively reduces the power consumption of real-time system 基于wcet(worstcaseexecutiontime)分析的結(jié)果,在操作系統(tǒng)或者編譯器等軟件的輔助下,實時動態(tài)電壓調(diào)節(jié)利用程序運行時間的動態(tài)變化,有效地節(jié)省了實時系統(tǒng)的能量消耗。
