Dynamic Translation Based on Decoding Guidance Optimization Techniques of DBT

Dynamic translation of instruction optimization technique based on decoding guidance identifies the information of source instruction in the decode stage. Optimizing operations include flag processing, register allocation and anomaly detection etc. The technique dynamically generates optimized target binary code at guiding translation stage, thus improving the efficiency of the dynamic binary translation system. This paper analyzes and achieves this optimization technique, and obtains improvement in performance provided by this optimization technique.
