【摘要】:對于指令級并行處理器(ILP,instruction level parallelism),在執(zhí)行不同應(yīng)用程式時,硬件資源的需求量差異很大,甚至在同一支程式中也是如此,某些空閑的硬件資源會產(chǎn)生額外的靜態(tài)能量,提出重新設(shè)置應(yīng)用程式中不同區(qū)塊的執(zhí)行并行度,把空閑的硬件資源關(guān)斷來降低靜態(tài)能量的方案,利用Core Mark Pro的標(biāo)準(zhǔn)測試集中的應(yīng)用程式進(jìn)行測試,靜態(tài)能量降低超過40%且執(zhí)行時間增加少于10%.
[Abstract]:For instruction-level parallel processors (ILP,instruction level parallelism), requires a lot of hardware resources when running different applications, even in the same program, some idle hardware resources generate additional static energy. This paper proposes a scheme to reset the execution parallelism of different blocks in the application, turn off the idle hardware resources to reduce the static energy, and use the application program in the standard test set of Core Mark Pro to test. The static energy is reduced by more than 40% and the execution time is increased by less than 10%.
