摘要

为了缓解嵌入式系统内存资源有限的问题,人们提出了代码压缩技术。随着技术的发展,降低片上总线的能耗对嵌入式系统设计者来说变得越来越重要。本文提出了一种串扰感知的高效码压缩方案,在不牺牲压缩比的前提下,降低线间耦合转换引起的指令总线能耗。实验结果表明,在TMS320C6x基准测试中,仅由于线间耦合转换导致的总线功耗降低了42-68%,总总线功耗降低了55-71%。

Crosstalk-Aware Energy Efficient Encoding for Instruction Bus through Code Compression
Code compression techniques have been proposed to mitigate the problem of limited memory resources in embedded systems. As technology scales, reducing on-chip bus energy consumption is becoming important for embedded system designers. In this paper, we propose a crosstalk-aware energy-efficient code compression scheme, which can reduce inter-wire coupling transition induced instruction bus energy consumption, without sacrificing compression ratio. The experimental results show that the bus power consumption due to inter-wire coupling transition alone is reduced by 42-68% and the total bus power consumption is reduced by 55-71% for TMS320C6x benchmarks.
