摘要
本文提出了一种新的多线程处理器模型，它结合了前瞻性执行机制和多线程执行机制，既能从更大的指令窗口中开发出更多的ＩＬＰ，又能屏蔽各种长延迟操作，达到较高的资源利用率。本文深入讨论了ＳＭＡ模型及其特点，并进行了初步的性能分析。
A new multithreaded processor model is presented in this paper.It combines speculative execution and multithreaded execution mechanisms.It can not only develop more ILPs in larger instruction windows,but also mask various long latency operations in order to attain higher utilization of resources.This paper discusses the model and its features in detail and conduct a primary performance analysis.
