Geyser-1是MIPS R3000原型CPU,在执行阶段为主要计算组件提供细粒度运行时PG。功能单元,如CLU,移位器,乘法器和分法器,在运行时进行电源门控和控制,以便只有要使用的功能单元通电,以尽量减少泄漏功率。在实际芯片上的评测结果表明,该细粒运行PG机构工作无电气问题。在25℃时降低泄漏功率7%,在80℃时降低24%。使用基准程序的评估结果表明,功耗在25°C时可降低3%,在80°C时可降低30%。
Geyser-1, a prototype MIPS R3000 CPU with fine grain runtime PG for major computational components in the execution stage is available. Function units such as CLU, shifter, multiplier and divider are power-gated and controlled at runtime such that only the function unit to be used is powered-on to minimize the leakage power. The evaluation results on the real chip reveals that the fine grain runtime PG mechanism works without electric problems. It reduces the leakage power 7% at 25 °C and 24% at 80°C. The evaluation results using benchmark programs show that the power consumption can be reduced from 3% at 25 °C and 30% at 80°C.
