Abstract
This paper describes the development of a programming environment supporting input in graphic form to improve the efficiency of transforming new algorithm concepts into a code set executable on a multiprocessor architecture. The user draws a signal flowgraph on the screen as if using a notepad. The system translates it into a form which can be executed on the Picot system, a multiprocessor system for processing video signals in real time. The new system, named PicPEn, consists mainly of a user-friendly graphics editor and an integrated compiler which breaks up the signal flowgraph, compensates for timing differences between processing nodes, and generates the machine code for each processor.
