摘要: A data processing system (10) has an interrupt controller (14) which provides request (30) along with a corresponding identifier (31) and vector (32) to processor (20). If the (20) accepts interrupt, returns same value by way of (34), acknowledge (33), (14). An taken/not taken indicator (35) may also be provided. The communications interface (60, 40, 70) used coordinate between asynchronous.
