Automatic Dynamic Binary Translator Generation from Instruction Set Description

Implementing a new target architecture in a full-system emulator is a labor consuming task. The most tedious part is to manually write a target machine code translator to emulator's internal representation. In this paper we describe an automated approach to this problem. In this approach a programmer writes a description of target instruction set encoding and instructions semantics. Our tools then generate a completely functional translator from these descriptions. The proposed tools were tested on Moxie architecture and have shown to be correct.
