Abstract:
Dynamic binary translator (DBT) is typically used for software migration or binary code optimization. In this paper, we describe the design and implementation of a multi-sources and multi-targets DBT–CrossBit, which aims at fast migrating existing executable source code from one platform to another alien target platform with lower cost. In order to support code translation among multi-sources and multi-targets better, a new intermediate instruction set– VInst, which is independent of any specific machine instructions, has been introduced. Unlike many other existing DBTs which directly translate the binary code of one instruction set architecture (ISA) to another ISA, CrossBit first converts source binary code to VInst specifications, and then transforms them into target platform code, using a granularity of a basic block (BB) as the unit of translation. Additionally, to address the performance issue, we adopt several generic optimization methods to optimize the translated code. Finally, our experimental result indicates that, for the SPECint2000 benchmarks, CrossBit’s performance is pleasant and can meet the design requirement.
