VLIW中指令级的并行处理分析

在研究超长指令 (VL IW,Very L ong Instruction Word)体系结构的基础上 ,总结了 VL IW体系结构的指令结构特征、处理器结构体征和执行特征 ,用VL IW的编译调度很好的提高了指令级的并行处理。提高指令级并行性是实现高性能中央处理器的主要手段 ,因而如何实现指令的动态调度和解决控制相关以及多指令流出 ,这就成为了开发一个指令级并行性能高的微处理器的关键所在。文中介绍了 VL IW的循环展开的指令处理技术 ,大大提高了指令的执行速度 ,从一个方面预示了 VL IW的发展前景。

Parallel Processing and Analysis in the VLIW Instruction Class

This paper summarize the character of the very long instruction word computer system architecture, and the character of the processing, and character of the execution. Using translate and edit of the VLIW can greatly increase the parallel disposal. The key method to improve the performance of CPU is to improve the velocity of parallel processing. So it becomes the most important key place to how to develop a high speed CPU. In the article, the technique of unfold circulation is introduced and speed the execution velocity of Instructions. It is open up vast vistas for VLIW in the future.
