摘要

对于实时系统，我们需要时间可预测的处理器。本文提出了一种方法缓存作为指令缓存的时间可预测解决方案。方法缓存缓存整个方法(或函数)并简化最坏情况下的执行时间分析。我们在时间可预测处理器Patmos中集成了方法缓存。我们使用大量的嵌入式基准来评估方法缓存。大多数基准测试显示，方法缓存大小在4到16 KB之间时命中率较高。

A Method Cache for Patmos

For real-time systems we need time-predictable processors. This paper presents a method cache as a time-predictable solution for instruction caching. The method cache caches whole methods (or functions) and simplifies worst-case execution time analysis. We have integrated the method cache in the time-predictable processor Patmos. We evaluate the method cache with a large set of embedded benchmarks. Most benchmarks show a good hit rate for a method cache size in the range between 4 and 16 KB.
