摘　　要：为了充分利用多核CPU来实现动态二进制翻译的并行化,研究了用多线程将翻译阶段和执行阶段并行优化的方法,提供了并行化系统的程序流程。并根据翻译与执行的时序及相关性,设计实现了一种超前翻译算法,它能够有效预测程序的执行路径,为翻译过程提供导向作用。实验结果表明,该优化方法提高了翻译缓存中基本块的命中率,使执行阶段尽量不被中断,进而提升了执行效率。To make full use of the multiple cores CPU, which is helpful to dynamic binary translation, a method of the parallel multiple thread dynamic binary translation is discussed and the procedure of the system is provided. According to the relativity on translation and execution, forward translation algorithm which can calculate the execution path is designed. Finally, the final experimental result show that the parallel method produces higher chance for translated blocks in the translation cache, and improve the execution efficiency.
