Real time comparison of integrated circuit operation

摘要: A pair of substantially identical integrated circuit elements, in the form microprocessors, are operated response to same instruction and data signals that accessed from a memory by one circuits. The signal supplied, via synchronous interface, second circuit, which operates thinking supplied were it address control signals. states two circuits applied comparator circuitry, both buffered paths. circuitry is produced first effect comparison on only those valid at any particular moment time. Clock-synchronizing included ensure predetermined state transitions clocks used operate occur within prescribed time period.
