计算机体系结构的设计思想在近四十年间发生了深刻的变化,而指令格式的设计是计算机体系结构设计的一个重要环节。该文首先介绍了一种典型RISC体系结构的指令格式,然后以IA-64为例对基于VLIW的指令格式进行了分析,并与RISC指令格式进行了比较,最后提出了一种新的基于VLIW的指令格式。
The design concept of computer architecture has undergone profound changes in recent forty years, and the design of instruction format is an important part of the computer architecture design. This paper first introduces the instruction format of a typical RISC architecture, then analyzes the instruction format based on VLIW using IA-64 as an example and compares it with the RISC instruction format. Finally, a new VLIW Instruction format.
