Abstract: Aiming at the coexistence of several address space in system-level binary translation, this paper presents 2 code Cache index methods using virtual-address index and physical-address index. Physical-address index helps to share translated code Cache between processes. Experimental results show that physical-address index achieves better performance than virtual-address index in multi-process environment.

Key words: system-level binary translation, physical-address index, virtual-address index

摘要： 针对系统级二进制翻译中多地址空间共存的情况，提出2种使用虚拟地址和物理地址对代码Cache进行索引的方法。物理地址索引方法有助于各个进程共享已被翻译的代码Cache。测试结果表明，在多进程环境下，物理地址索引的性能高于虚拟地址索引。
