Abstract
A computing system includes (1) a primary processor executing executable instructions and generating first instruction data associated with the executable instructions, (2) a secondary processor executing the executable instructions one or more clock cycles behind the primary processor and generating secondary instruction data associated with the executable instructions, (3) a first first-in first-out (FIFO) buffer for the primary processor, (4) a second FIFO buffer for the secondary processor, (5) circuitry storing at least some of the first instruction data in the first FIFO buffer and at least some of the second instruction data in the second FIFO buffer, (6) compare circuitry comparing a first portion of first instruction data and a second portion of second instruction data that are associated with a given clock cycle, and (7) control circuitry halting the primary and secondary processors responsive to a mismatch between the first portion and the second portion.
