摘　　要：传统的片上多核结构存在着计算资源粒度固定的缺点,无法满足应用在不同阶段对计算资源的差异化需求.针对上述问题,本文设计了运行时逻辑核可调整的可重构众核流处理器及流程序映射方案,以期满足应用各个阶段对计算资源的需求,且不造成资源浪费.通过在时钟精确软件模拟器上评估不同类型应用的性能表现,分析了处理器主要设计参数对性能的影响.实验结果表明,与具有同样计算资源的固定粒度流处理器相比,本文设计的可重构众核流处理器能够获得10%-30%的性能提升.Traditional chip multiprocessors deploying fix architecture design can not satisfy the diverse demands for computational re- sources during different execution phases. To address the above issue, we propose a runtime-reconfigurable manycore stream proces- sor with multiple stream program mapping methods, to satisfy the requirements from different execution phases without wasting com- putational resources. We then use a clock accurate software simulator, to evaluate the performance of the stream processor we pro- posed, as well as exploring the design space of this stream processor. The experiment results show that, compared with those fix-de- sign stream processors which have same computational resources, our design can obtain significant speedup from 10% to 30%.
