二进制翻译中代码Cache的分级双粒度管理策略

New Code Cache Management Scheme in Binary Translation

提出一种二进制翻译中代码Cache管理的LRC(Level-Region-Chunk)策略。其兼具全清空策略、FIFO策略和多级Cache的优点,并且考虑了程序的时间空间局部性、执行特性和替换开销,具有较好的性能,实现了代码Cache的高效管理。

It is an important issue that manage the code cache efficiently in the binary translation technology. This paper presented LRC（Level-Region-Chunk） scheme that was a new code cache management scheme. It integrated the merit of the full flush scheme, FIFO scheme and multi-level cache, and took the temporal and spatial locality and code replacing overhead into account. It has good performance and efficientlv manages the code cache.
