Abstract
An information processing system has a plurality of processor circuits, each of the processor circuits including internal circuits and an internal processing result outputting circuit, the system having an internal data selection circuit connected to each of the processor circuits and at least one fault detection circuit. The internal processing result outputting circuit of each of the processor circuits outputs respective result data processed by respective ones of the internal circuits in the processor circuit. Each of the internal data selection circuit selects and outputs one selected result data output from the internal processing result outputting circuit of each of the processor circuits, at a predetermined timing. The fault detection circuit outputs a result of a comparison among the data selected by the respective internal data selection circuits of the processor circuits or among the data output at each predetermined timing by the processor circuits.
