In a real-time process control environment, it is common for a processor to spend a sizable amount of time servicing interrupts. It is reasonable, then, to search for methods to decrease this time. One such technique involves the implementation of the routine at the microprogram level.This paper relates to the comparison of a microprogrammed and machine-level programmed interrupt service routine. It is shown that a reduction in time spent in the routine is achievable using microprogramming.
