Definition of architectures capable of fault tolerance and reconfiguration, suitable for very large scale integration (VLSI) implementation, is an important problem with regard to both production yield and run-time availability of VLSI devices. The case considered in the present paper concerns regular arrays of processing elements, such as the ones found in(More)
In 1981 a national research program for the design, simulation and construction of a multiprocessor image processing system was started. After a first phase devoted to the comparison of suggested and existing systems and to the definition of a set of benchmarks and to the evaluation of the performances of the major classes of machines, a new system has been(More)
