摘要： Methods and systems are provided for analyzing parallelism of program code. According to a method, the sequential execution of the program code is simulated so as to trace the execution procedure of the program code, and parallelism of the program code is analyzed based on the result of the trace to the execution procedure of the program code. Execution information of the program code is collected by simulating the sequential execution of the program code, and parallelism of the program code is analyzed based on the collected execution information, so as to allow programmers to perform parallel task partitioning of the program code with respect to a multi-core architecture more effectively, thus increasing the efficiency of parallel software development.

摘要： Disclosed is a method of recognizing a process in a full-system Instruction Set Architecture (ISA) emulator, comprising the steps of: recognizing a process based on a base address of a page table thereof, recognizing the switch between the processes when said base address of the page table has changed, recognizing the termination of a recorded process when the base address of the page table of the process which tries to modify the page table is not equal to the base address of the page table of the recorded process in the page table. With the recognized process, the binary translation results indexed based on content can be saved into a corresponding process repository, thereby achieving the permanent saving of the translation results and the reuse of translation and optimization on the basis of a previously executed program. Consequently, the overall performance of the full-system Industry Standard Architecture emulator is enhanced.
