开拓数据驱动计算的高度并行度,要求程序工作者充分分析一维表达形式的程序段中的数据相关,进而将其转换成易于并行执行的二维形式的数据流程序图;要求系统结构工作者,要设计出能保证执行这种二维程序图的计算机系统,包括能提供高度并行执行程序图的操作执行机构和适应异步操作特点的包通信机构。本文,从数据流计算机的互连结构的角度出发,研究了当前的数据流计算机的系统组织原理:论述了适合于数据驱动操作特点的包通信机构;分析了目前数据流计算机中几种包开关互连结构在此基础上,评价并初步探讨了用于数据流计算机中的各种可能的互连网络,
To develop highly parallel data-driven computing requires programmers to fully analyze the one-dimensional representation of the data in the program segment, and then convert it to a two-dimensional form of easy-to-parallel execution of the data flow diagram; require system structure workers , To design a computer system that will ensure the implementation of such a two-dimensional program graph, including an actuator that provides a high degree of parallelism in the execution of program diagrams and a packet communication mechanism that adapts to asynchronous operation. This paper, from the point of view of the interconnection structure of data flow computer, studies the system organization principle of the current data flow computer: discusses the packet communication mechanism suitable for the characteristics of data-driven operation; analyzes several packet switches On this basis, the interconnection structure is evaluated and preliminary probed into the various possible interconnection networks used in data flow computers,
