A synchronous or asynchronous event that occurs, requiring the attention of the CPU to take some action. A special program that is run in order to service a device, take care of some error condition, or respond to an unusual event. When an interrupt is accepted by a typical CPU, criti- cal processor status information is usually saved here. The highest priority interrupt in a system, one that will never be ignored by the CPU. A signal that causes the CPU to reinitialize itself and/ or its peripherals so that the system starts from a known state. The process of identifying the source of an interrupt and locating the service routine associated with it. When this occurs, the device in question places a num- ber on the bus that is read by the processor in order to determine which handler should be executed. Another name for a software interrupt, this is a syn- chronous event occurring inside the CPU because of program activity. On some systems, the "blue screen of death" can result from this type of software-related exception. These are mapped in a system's I/O address space; they allow data and/or control information to be trans- ferred between the system bus and an I/O device. A technique that features a single, common address space for both I/O devices and main memory.
