摘要：

为了实现快速映射间接分支目标地址,提出地址索引映射表法,使用地址数组按源地址顺序保存所有对应的目的地址,索引数组存储源地址在地址数组中的索引位置,只需要几条指令就可以完成源地址到目的地址的映射,提高了执行速度.为了加快函数的调用处理,提出将本地栈作为影子栈、与本地库函数封装相结合的方法.本地栈模拟参数传递和返回,加速函数调用.结合封装接口处理参数和返回值,实现间接调用本地库函数,提高了函数处理能力.基于上述方法和QEMU,设计并实现了静态二进制翻译系统SQEMU.基于SPEC2006和nbench测试集,从x86平台翻译到Alpha平台的实验表明,SQEMU相对QEMU平均加速比分别达2.09倍和6.39倍.
Abstract:

Address indexed mapping table (AMT) was presented to efficiently handle indirect branches. An address array was used to store all target addresses, and an index array was used to contain the index values of all source addresses in address array. Using index, only several instructions were used to map a source address to the corresponding target address, and the speed of execution was improved. An approach combining shadow stack and native library jacketing was presented to efficiently handle function call. The speed of function call was improved by passing parameters and returning value in native stack. Native function can be indirectly called by handling parameters and return value of native library function through jacketing interface. Static QEMU (SQEMU) was designed and implemented based on these approaches and QEMU. For x86 codes to Alpha platforms, SQEMU gains factors of 2.09 and 6.39 times speedup over QEMU for the SPEC2006 and nbench benchmarks respectively．
