Question: 1. An interrupt system must allow asynchronous events to interrupt an ongoing process." Give rive more hardware and software attributes of an interrupt system.
2. Design the hardware for an input interrupting device in a polled interrupt system. Assume an 8-bit switch register for data. a one-bit status register for an "I did it" big and a push-button switch to generate a wired-OR IRQ_1. signal. The status regis-ter and switch register are each to occupy an address in the 8-bit I/O address space. Assume separate I/O with control signals READ_L and WRITI_L.
