摘要
嵌入式开发对指令集模拟器模拟速度的要求越来越高。提出了一种新的细化的动态翻译技术,基本思路是指令集的每条指令被翻译成一条语义函数,通过特定的指针指向符合条件的语义函数,这样,即使执行条件发生改变时也能调用上次编译的结果,从而使模拟速度显著提高,MIPS64指令集模拟器的测试结果给以了验证。
The simulation speed of ISS（Instruction Set Simulator）is an important element in the development of embedded system.The paper gives a new special dynamic compiled simulation technique,basic mentality is that every instruction is decoded into a semantic function,and it adopts a particular pointer pointing a correspondent semantic function according with conditions.In this way,even if performance condition changes,ISS can also call the result compiled last time,so the simulation speed is improved obviously.The tests of MIPS64 ISS based on the technique show it.
