ABSTRACT:
A fault tolerant data processing system includes a pair of processors for simultaneously executing commands for processing data, a memory, and a data transmission bus between the processors and the memory voer which the processors may fetch data from and write data to the memory. A comparison circuit is included between the processors for comparing the data fetched and written by the processors. A rollback module is responsive to the comparison circuit for rolling back the operation of the processors to the beginning of a presently executing command in the event of a miscomparison by the comparison circuit.
