ABSTRACT:
A fail-safe multiprocessor system comprises processors connected through a switching unit which forms a data transfer channel between the processors. This switching unit comprises mechanical switches that can selectively connect peripheral units (e.g., display units) with one of the processors. The transfer device constitutes, from the standpoint of each of the connected processors, a normal peripheral unit. The switches are set either manually or automatically under program control by each of the processors. In the case of an error or failure, the data processing system is reconfigured such that the high priority tasks together with their associated peripheral units are transferred from the failed processor to a processor which is still intact.
