Binary translation method using intermediate command set

Abstract

The invention relates to a binary translation method which uses the intermediate instruction set; a set of intermediate instruction set is designed as an intermediate level which is used during translating one machinery directive into another machinery directive, and can effectively separate the source machine from the target machine; intermediate instruction set includes basic instructions matched with a mainstream machinery instruction set; the basic instructions is divided into mapping instructions of the register state, memory visit instructions, data moving instructions, computing instruction, as well as control, transfer and special instructions; when the machinery instructions needs translating to intermediate instruction, common instructions of the source machine can be directly mapped to a piece of intermediate instruction; while strange instructions can be translated into a plurality of intermediate instructions or can be simulated by C function; through adopting the intermediate instruction set, the invention can correctly shown the instructions of machine with various system structures, and can greatly reduce the complexity of the binary translation machine which can support multi-platform of source and target machines, thereby realizing the redirection of the binary translation machine, and playing a very important role of optimizing the system structure, as well as the system performance of the binary translation machine.

Description

technical field [0001] The invention relates to a binary translation method using an intermediate instruction set, which can translate one physical machine instruction into another physical machine instruction by using a set of intermediate instruction sets for binary translation. The invention belongs to the technical field of binary translation. Background technique [0002] Binary translation is a simulation technology that involves two machine platforms, "Source" and "Target", so the binary translator has a strong dependence on the machine platform, which poses a challenge to the portability of the basic platform. Higher requirements, redirectability is one of them. Redirectability refers to the support of the basic platform for multiple source machines and target machines, and can be easily transplanted to new machine platforms. The intermediate instructions effectively separate the source machine and the target machine, and are reconfigurable. The essential. In a bi...

Problems solved by technology

[0004] If you use an existing intermediate language in binary translation, you need to consider its adaptability to the new environment - including both the front-end language and the back-end language; you need to consider the cost of porting and reusing existing A trade-off between the overhead inherent in design and code; existing intermediate languages ​​are designed for compilers, where the source language is a high-level programming language and the target language is machine language, whereas in binary translation, the source and target The language is all machine language, so the intermediate language should be a machine-level language, so the existing intermediate language is not completely suitable for the application environment of binary translation
