Abstract
A multiprocessing system has a plurality of processors each having a unique interrupt. An executive processor issues interrupt requests over a global bus having a plurality of interrupt lines. A plurality of bus interface systems are each connected to a different interrupt line in the global bus and to a cell bus. A master cell processor and a plurality of slave cell processors are connected to different interrupt lines in the cell bus. All interrupt requests to a cell go first to the master cell processor and then to a slave processor as appropriate.
