| Research Abstract |
This research developed a method of thread-level parallelization for the speculative multithreading, that enables both the enlargement of thread codes and the removal of the data communication between threads, by introducing a speculative multithread execution method based on the execution path of programs. A software proto-type system have been developed, while solving the three primal problems (1)development of the high-performance thread-level parallelization based on the execution path of programs,(2)development of the software accurate path profiling system at low cost,(3)realization of high-performance speculative multithreading only by software.
