Graphic oriented signal processing language-GOSPL

In an effort to produce more efficient means of transforming new algorithm concepts into working models, this paper describes the development of a digital signal processing workstation accepting input entirely in graphic form. This Graphic Oriented Signal Processing Language (GOSPL) accepts flow graph information in block diagram form using a mouse input device. The researcher uses the mouse to describe graph connections and create function blocks in the flow graph by selecting them from a menu. The system executes a broad class of flow graphs and provides virtual instruments to monitor signals throughout the graph during real-time execution.
