一种具有高性能价格比的产品计算机辅助设计与仿真平台

摘要

This paper presents a high performance of CAD&CS platform system,which makes use of mainstream PC(Personal Computer)、high-speed PCI bus and tight-coupled multiprocessors structure.It has high-speed computation,fast communication,high data throughput ability and high performance-price ratio.We analyze the hardware architecture,major characteristics of the system.Also a performance evaluation and simulation is done to the system,the results demonstrate that the system has a high performance-price ratio,and can meet the needs of the most CAD&CS applications.%该文提出了一种利用主流微机(PC机)、采用机间高速PCI总线和紧耦合多微处理机结构组成的、具有高速计算能力、高吞吐率和高通信能力的计算机辅助设计与仿真(CAD&CS)平台系统。文章分析了该系统的硬件体系结构、主要特点并对其性能进行了仿真评估。仿真结果表明,该系统能满足大多数CAD&CS应用的要求具有较高的性能价格比。
