ABSTRACT:
A method and apparatus is provided for generating an interrupt signal in a data processing system, the interrupt signal being supplied to a control processor of the system to indicate the occurrence of any of a plurality of predetermined events in the system. The method and apparatus operate by: writing data to at least one memory location of a plurality of pairs of memory locations A,B of the system in dependence upon the event to be indicated, the pairs of memory locations A,B being predefined in the system for respective ones of the events; reading data from the pairs of memory locations A,B; processing the data read from each pair of memory locations A,B to generate interrupt data indicative of whether the associated event has occurred, and if so transmitting an interrupt signal to the control processor; and writing the interrupt data corresponding to the events to respective third memory locations C, the third memory locations C being predefined in the control processor for the events. On receipt of an interrupt signal, the control processor reads the interrupt data in the third memory locations C to determine the event indicated by the interrupt signal.
