摘　　要：数据流计算机作为新一代并行机迅速发展起来，但由于数据流模型本身的局限性，使得商用数据流机器的制造还难于普及．本文通过分析运算的操作字符与非操作字符，改进传统模型的点火规则、引入变量并拓广变量的概念，定义了粗粒度数据流模型ＣＤＦＭ（ＣｏａｒｓｅｇｒａｎｕｌａｒｉｔｙＤａｔａＦｌｏｗＭｏｄｅｌ）．As a new generation of parallel computer,data flow computer has developed very quickly, but because of its own deficiency,it is very difficult to build dataflow computers for commercial use. In this paper, by analysing the operating words and non-operating words of computation, modifying the firing rule of traditional dataflow model, introducing variables in the model, they will define a Coarse granularlty Data Flow Model CDFM.
