> 中文摘要: 如何进行异构机之间可执行程序的高效移植是二进制翻译面对的难点问题.从寄存器映射的角度分析了这一问题,提出了分段映射和特殊寄存器功能剪裁相结合的方法,以trend系统为平台进行了实验和测试.NPB-serail测试包和SPEC2000测试包的测试结果显示:使用该方法,可以简化指令翻译,减少代码膨胀,有效提高翻译后代码的执行效率.
Abstract:How to migrate binary code between different ISA efficiently is a difficult problem in binary translation. This paper analyzes this problem at the aspect of register mapping and an innovative register mapping method combining segment mapping and function cutting out of special-purpose register has been presented in this paper. An implementation of the method has been done on trend, which is a dynamic binary translation system translating and executing binary code of PowerPC on Alpha. The testing results of NPB-serial and SPEC2000 show that the method can simplify instruction translation, decrease code expanding and improve the execution efficiency of binary code obtained after binary translation evidently.
