Abstract: Peripheral unit controller in a data processing system. The peripheral unit controller consists of two subprocessors (100a, 100d) whose outputs are matched. In addition, each duplicated subprocessor contains a pair of microprocessors (300, 307) whose outputs are also matched. The synchronization scheme allows each microprocessor (300, 307) to ran its own diagnostics independently, and to synchronize itself with the other microprocessor of the pair. After the synchronization occurs in both microprocessors in each of the sub-processors, the sub-processors are synchronized. Synchronization is achieved by using a real-time clock and the interrupt structure of each microprocessor.
