跳转链接技术在动态二进制翻译中的应用

Chaining Technology Used in Dynamic Binary Translation

动态二进制翻译中,翻译和执行的基本单元是基本块。一个基本块执行完毕,程序的控制权必须回到执行引擎,开始下一个基本块的查询,这导致频繁的控制权切换。对基本块应用跳转链接技术能够减少这种频繁的控制权切换。该文总结了二进制翻译器中一些常用的跳转链接方法,包括翻译块链接、路径线性化、分支预测等,并通过实验数据证实了跳转链接技术的有效性。

For Binary Translation,the unit of translation and execution is a basic block.After a basic block is executed,the control of the program must return to the execution engine,and start a new enquiry to the next basic block,which led to control switching frequently.Translation chaining technology can be used to reduce this switching.This paper summarizes some chaining technology commonly used in binary translators,such as Translation Linking, Trace Linearization,Software indirect jump prediction,etc.In addition,we test the effectiveness of the chaining technology in CrossBit.
