| 摘 要： | 复杂指令集计算机体系结构向精简指令集计算机体系结构的动态二进制翻译过程中经常出现地址不对界的问题。本文以I386到Alpha平台的动态二进制翻译为例,研究了内存映射时的不对界和数据存取时的不对界问题,提出了一种改进的内存映射方法以及在中间表示层处理不对界地址访存问题的方案,有效地解决了此类问题。经实验验证,该方法正确并有较高效率。

| Abstract: | The address of a piece of code is often misaligned when running the instructions of complex instruction set computer(CISC) architectures on reduced instruction set computer(RISC) architectures in binary translations. To deal with the misaligned address problems,this paper studies the memory mapping and the load/store instructions in intermediate representation based on the dynamic binary translation from I386 to Alpha,and presents a scheme which is able to solve these kinds of problems. The results of the tests prove that the scheme is effective. |
