The invention provides a method for dynamically monitoring an execution flow of a binary translator by using a monitoring thread, which comprises the following steps that: firstly, a new program monitoring thread MT is created for the prior dynamic binary translation system; and secondly, a stub code is inserted in each translation-generating basic block, wherein when executed, each basic block write the entry address thereof into a queue, and queue overflow is prevented by interthread wait; thirdly, the monitoring thread MT is responsible for taking the entry addresses out sequentially, searching for corresponding intermediate instruction basic blocks, updating corresponding data structure according to the termination types of the basic blocks and completing the program monitoring; and finally, referring to part of collected information, the monitoring thread, as a decision maker, completes the optimization of the establishment of a heat path. Compared with the prior program monitoring ...

The invention relates to a program execution optimization method on basis of copying codes for forming superblock in the computer technical field. The method comprises the following steps: programs are divided, the detection command is inserted to construct an intermediate language superblock, then the balance mechanism parameter of the intermediate language superblock is set and generated, screening guide treatment is performed; and the intermediate language superblock is translated to a target superblock, and the target superblock is executed by a binary translator. The invention is used to generate the superblock by copying the codes of basic blocks, thus the length of basic blocks is increased, the number of basic blocks is reduced, the quality of the superblock is improved, and the portability is good.
