Scheduling of concurrent processors in a real-time image processing system on FPGA (Field programmable gate array) hardware is a not a trivial task. We propose a number of graphical representations for scheduling which were evaluated for use in a visual language for image processing on FPGAs. The proposed representations are illustrated and their strengths and weakness discussed and the reasons for adoption of the state chart notation are given.
