ABSTRACT:
In a multiprocessor system, at least one processor is acting as a master processor and another processor is acting as the slave or shadow processor that checks operation of the first processor. Periodically, a controller switches operating mode of a master or main processor to slave or shadow mode, and at the same time switches operation of a slave or shadow processor to main or master processing mode. The first processor is then used as a slave or shadow processor to check operation of the second processor.
