摘要
在国产神威服务器上实现了一种采用直译方法的动态二进制翻译系统,能将x86体系结构下的机器码直接翻译为申威处理器架构下对应的机器码,实现x86程序在异构的神威服务器上的系统级仿真;采用静态预先译码的方法提高译码效率;提出了一种适用于RISC处理器的翻译框架,方便移植,有利于翻译生成的目标机器码进一步优化。
A dynamic binary translation system using direct translation method has been implemented on the domestic ShenWei server. It can directly translate x86 machine code into ShenWei code and realize the system-level simulation of x86 program on the heterogeneous ShenWei server. A static pre-decode method is used to improve the efficiency of decoding. We propose a translation frame-work for RISC processor which is easy to be transplanted , and conducive to further optimization of the target machine code.
