integrated circuit PIC A special-purpose integratedcircuit that functions as an overall manager in an
interrupt driven system. It accepts requests from the
peripheral equipment, determines which of the incoming
requests is of the highest priority, ascertains whether the
incoming request has a higher priority value than the level
currently being serviced, and issues an interrupt to the CPU
based on this determination.
