Using improved data flow diagrams for hardware description
Ming Su, Hongxi Xue, Qingsheng Wang · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1996
The data flow diagram has been widely used in software engineering. However, previous definitions of the data flow diagram have not provided a comprehensive way to represent the behavior and structure of hardware. This paper describes an improved data flow diagram which provides notations, syntactic rules and semantic interpretations for hardware description. It is a kind of visual language and supports mixed-level and hierarchical description, module configuration, attribute specification, multilevel timing specification.
