本文讨论了可重组结构计算机体系中的一个重要问题——系统资源间相互通信问题.文中,首先指出了冯.诺依曼型计算机结构中指令按严格顺序执行和对数据不加区分使高速并行计算受到的障碍,接着分析了计算机体系固定结构的局限性,从而引出了可重组结构计算机体系的概念;然后着重对所推荐的体系中的64个功能单元,利用16个总线单元进行相互通信的四个具体方案作了详细的讨论,并对它们的优缺点作了扼要的比较.
This article discusses one of the most important problems in reconfigurable architecture computer systems-the problem of system resources communicating with each other. In this paper, we first point out that the commands in von Neumann-type computer architecture are executed in strict order and indistinguishable from the data, Then the paper analyzes the limitations of the fixed structure of the computer system and leads to the concept of a reconfigurable computer system. Then, we focus on the 64 functional units in the proposed system and use 16 bus units to communicate with each other Four specific programs were discussed in detail, and their advantages and disadvantages were briefly compared.
