摘要： 作为一种有效提高指令级并行度的方法,超长指令字(VLIW)体系结构被看做RISC技术的自然延伸VLIW。体系结构通过编译器静态调度发掘程序中潜在的并行性,从而有效地降低了硬件复杂度。该文结合Intel公司的IA-64体系结构与Transmeta公司的Crusoe芯片介绍VLIW技术的一些最新发展,并通过IBM的Tree-VLIW结构探讨VLIW处理器目标代码的兼容性问题。

Abstract: In this paper we present the Intel IA-64 architecture and crusoe chip from transmeta corp. Such architecture or chip is based on VLIW architecture to further exploit the ILP. Also, we discuss some problems of object-code compatibility encounted by VLIW processors.This paper aims at providing a general view on VLIW structure and raises a discussion on its virtues as well as its pitfalls.
