Abstract

How to effectively utilize the rich transistor resources provided by multi-core to accelerate the execution of serial programs is currently a hot issue in research. Thread-level speculation(TLS) technology aims at making full use of multi-core resources and maximizing the potentially parallelism in serial code. At present, TLS technology has been effectively utilized to parallelize several serial applications. However, speculative thread level parallelism in embedded applications has not yet been explored thoroughly. Therefore, this paper analyzed eight selected representative embedded applications from their potential parallelism and runtime characteristics(data dependency, thread granularity and parallel coverage) in loop-level speculation. The experimental results show that for embedded applications, the speculative thread level parallelism is better than that in instruction level parallel technology, and the maximum speed up in experiment achieves 13.29. In the field of embedded applications, the technology can effectively utilize resources of 4 to 8 core computing.
