The processor stops what it was doing and calls the code at a specific location, determined by the type of interrupt. Tami Meredith, Ph.D.. CSCI 3431. Why?. Devices need CPU access. E.g., NIC has a full buffer it needs to empty. These device needs are often asynchronous and unrelated to the currently executing process. Design of Microprocessor-Based Systems. Mark . Brehob.
