时钟共享多线程处理器通信机制的设计与实现

Design and implementation of communication mechanism for a shared-clock multithreading processor

多核多线程处理器^([1])是并行技术的一个发展方向,基于多核多线程处理器,提出了一种时钟共享多线程处理器。该处理器有近邻通信和线程间通信两种通信机制,近邻通信采用近邻共享FIFO来传递信息,线程间通信通过线程间共享存储来传递信息,这样可以提高处理器的资源利用率和并行执行能力。

Multicore and multithreaded processors is a development direction of parallel technology. This paper design a shared_clock multithreading processor for multicore and multithreaded processors. It has two communication mechanisms ： the neighbor communica-tion and the thread- thread communication. The neighbor communication conveys information by the neighbored shared FIFO and thread- thread communication conveys information by shared memory. This can improve resource utilization and parallel executing ca-pacity.
