Trace Cache 1 前言 当今应用程序对处理器性能的需求不断增加,而改进指令提取的机制,使得处理器能以更短的时间读取更多的指令,能有效提高处理器的性能。Trace Cache正是一种可以加快指令提取的技术。相比于指令Cache存储静态代码块,Trace Cache存储的基本单元是动态的指令流,可以有效减少取错指令的情况。例如,在...

The objective of this paper is to improve the use of the hardware resources of the trace cache mechanism, reducing the implementation cost with no performance degradation. We achieve that by eliminating the replication of traces between the instruction cache and the trace cache. As we show, the...
Applying different supply voltages to each different region of the trace cache, we can reduce the dynamic power consumption. However, we can know that the region which is supplied with lowered voltage inevitably deteriorates the performance of the trace cache by 5.7%. 展开 关键词: DVFS Trace ...
