Abstract

The increasing demand for wearable medical devices, coupled with their short battery life, has led to a renewed interest in low power processors. A significant proportion of the total power consumed by these medical device processors, occur in the memory systems, and therefore the focus of sour work. In this paper, we propose a technique that reduces the static power consumption in caches with no side effect on processor perforemance. Our proposed architecture achieves this power saving by deterministically lowering the power state of cache lines that are guaranteed not to be accessed in immediate future cycles. We simulated our architecture across different cache configurations, using widely known CAD tools, and observed up to 92% reduction in static power consumption on SPEC2006 benchmarks with no performance penalties and minimal hardware overhead.
使用记忆小睡控制器降低可穿戴医疗设备的泄漏功率
对可穿戴医疗设备的需求不断增加,加上电池寿命短,导致人们对低功耗处理器重新产生了兴趣。这些医疗设备处理器所消耗的总功率的很大一部分发生在存储系统中,因此是酸工作的重点。在本文中,我们提出了一种技术,可以减少缓存中的静态功耗,而不会对处理器性能产生副作用。我们提出的架构通过确定性地降低缓存线的电源状态来实现这种节能,这些缓存线保证在未来的周期内不会被访问。我们使用广为人知的CAD工具在不同的缓存配置中模拟了我们的架构,在SPEC2006基准测试中观察到静态功耗降低了92%,没有性能损失,硬件开销最小。
