ABSTRACT:
A high speed priority interrupt system which permits a microcomputer to service a plurality of peripheral units on a priority basis is provided. Interrupt address jump vectors corresponding to the routines for servicing the peripheral devices are stored in a read only memory and are selectively transferred to a program counter in accordance with a predetermined priority basis to allow the microcomputer to interrupt its program and service one or more peripheral devices requesting access to the microcomputer. The interrupt system minimizes the time required by the microcomputer for interruption of the current program, servicing of the peripheral units, and resumption of the interrupted program.
