Visual debugging for a pyramidal machine

This paper proposes a novel approach to program development for highly parallel architectures, primarily as far as debugging is concerned. The visual nature of the debugging stage, when dealing with image-processing algorithms, is heavily supported so that all the relevant information, which is generally either hidden or presented without its logical structures, is made available to programmers. The authors present the modular and portable software system built, in Pavia University, for the PAPIA2 machine
