  • System and method for simulating a multiprocessor environment for testing a multiprocessing interrupt controller
    Patent number: 5862366
    Abstract: A multiprocessing system comprising a plurality of processors and a plurality of I/O devices. A central interrupt control unit functionally intercouples the plurality of processors and I/O devices. The central interrupt control unit is configured to receive interrupt signals from the I/O devices and is configured to distribute interrupt signals to the processors. One of the processors is configured as a master test processor to control a test mode for testing the central interrupt control unit. The master test processor is further configured to release the other processors and emulate a multiprocessing environment.

  • System and method for testing and debugging a multiprocessing interrupt controller
    Patent number: 5790871
    Abstract: A processing system comprising at least one processing unit, a plurality of I/O devices, and a central interrupt control unit intercoupling the processing unit and the plurality of I/O devices. The central interrupt control unit is configured to receive interrupt signals from the I/O devices and is configured to distribute said interrupt signals to the processing unit. The central interrupt control unit is further configured to provide a signal simulative of an interrupt signal to simplify the testing process.
