摘要: 针对二维SIMD结构,提出一种基于可以动态关闭空转部件的,且由结合编译器、指令集和体系结构支持的低功耗调度算法。,其中包括编译器优化二维SIMD指令,功耗指令发出部件开关信号,系统接收信号并执行。采用对不同功能计算单元和存储单元的分别调度,的方式和并且采用了部件局部化的方法。在模拟器上的实验结果表明此该方法可以节省整个系统约15%的能量消耗。

Abstract: For According to 2Dd SIMD architecture, this paper presents a low low-power schedule algorithm which combines compiler, instruction set and micro architecture’s support, and it can close idle components dynamically. This algorithm contains compiler optimizing 2D SIMD instructions., Power instructions sendinsg switch signals., The system receivinges and executes these signals and executing. It involves different methods for computing unit and memorydifferent function units separately and. It also involves localizepartition unit method. The result of eExperimentsal result on simulator shows that this algorithm will can save about 15% of the total system’s power consumption.
