| Abstract(in English) | We have proposed a processor architecture, called SKY, which efficiently executes multiple threads in parallel for non-numeric programs with multiple processors. This paper shows comprehensive performance evaluation results and analysis of SKY. Our evaluation results show that SKY architecture achieves good performance improvements over a single superscalar processor, but a large difference of speedups is found among benchmark programs. We analyze what causes the difference by investigating instructions issued from the instruction window. We then found that the speedup significantly changes depending on existence of threads that can be executed in parallel and interference of multithreading execution with exploiting instruction-level parallelism. |
