  • Decoupling apparatus for verification of a processor independent from an associated data processing system
    Patent number: 4553201
    Abstract: In a data processing system having a plurality of CPUs, each CPU is operatively connected to other portions of the data processing system through a system interface unit. The CPU includes a cache memory, an execution unit, and a control unit. Further, each CPU includes an apparatus for verifying the operability of the CPU independent from the operation of the data processing system, which comprises a switch element, interposed between a first port of the CPU and the system interface unit, for decoupling the CPU from said system interface unit in response to a decoupling control signal. A detecting element, detects whether the CPU and the system interface unit are operatively connected to generate a configuration signal indicating the status of the operative connection. A maintenance panel is connected to the switch element and to the detecting element via a second CPU port.
