Visual data-parallel programming for signal processing applications
Matrix manipulation programs are easily developed using a visual language. For signal processing, a graph of tasks operates on arrays. Each task iterates the same code on different patterns tilling these arrays. In this case visual specifications of dependencies between the pattern elements are enough to define an application. From the ARRAY-OL language developed by Thomson Marconi Sonar, we propose a graphical environment, GASPARD, dedicated to the data-parallel paradigm. Only elementary SPMD tasks are textual. A full environment has been implemented; it includes a graphical editor, a code transformer and a code generator for SMP computers.
