VLIW体系结构微处理器的控制流分析与其模拟软件设计

CONTROL FLOW ANALYSIS AND SIMULATOR DESIGN FOR VLIW ARCHITECTURE MICROPROCESSOR

本文在研究超长指令字 (VL IW)体系结构的基础上 ,总结了 VL IW体系结构的指令结构特征、处理器结构特征和执行特征 ,通过比较 VL IW体系结构微处理器模拟器的两种设计方案 ,选定以结构为基础设计模拟器的方案 ,并解决了模拟器的设计难点——串并行冲突的问题 .

Based on the analysis of VLIW(Very Long Instruction Word) architecture, this paper concludes VLIW architecture's characters in three aspects: instruction structure, microprocessor structure and execution, establishes the structure-based scheme by comparing the two schemes, and solves the problem in simulator designing---the conflict between the parallelism of hardware and sequence of software.
