摘要

粗粒度的可重构体系结构旨在同时实现性能和灵活性。然而,功耗对于可重构架构作为嵌入式系统中具有竞争力的处理核心来说同样重要。在本文中,我们将展示在典型的粗粒度可重构体系结构中如何消耗功率。基于电源击穿数据,我们提出了一种功耗敏感的配置缓存结构和代码映射技术,在不降低性能的情况下降低了功耗。实验结果表明,在减小配置缓存大小的情况下,该方法可以节省大量的功耗

Power-Conscious Configuration Cache Structure and Code Mapping for Coarse-Grained Reconfigurable Architecture
Coarse-grained reconfigurable architecture aims to achieve both performance and flexibility. However, power consumption is no less important for the reconfigurable architecture to be used as a competitive processing core in embedded systems. In this paper, we show how power is consumed in a typical coarse-grained reconfigurable architecture. Based on the power breakdown data, we suggest a power-conscious configuration cache structure and code mapping technique, which reduce power consumption without performance degradation. Experimental results show that the proposed approach saves much power even with reduced configuration cache size
