摘　　要：片上多线程处理器是在一个芯片上集成多个多线程处理器核的高性能处理器系统。线程以CMP、SMT两种方式并行执行,显著提高了处理器性能。然而,从单核到多核,不仅仅是处理器核心的数量的增多,同时对处理器体系架构、存储系统、操作系统等相关领域提出巨大的挑战。对现有CMT系统研究现状进行了充分的研究和分析,在此基础上提出了静态任务层次分配策略和动态线程协同调度策略。Chip Multi-Threading is a high performance processor system by integrating several SMT processors on one chip.Multi-threads are processed concurrently in the way of CMP and SMT.The performance is significantly increased.However,from single processor to multi processors,not only the number of processors increases,but also encounters many new challenges in processor architecture,storage,operating system and so on.This paper analyses the research actuality of CMT system,over which the research on scheduling strategy is carried out
