Abstract

This article suggests that a selector be added to interrupt-handling hardware in order to permit a microprocessor to directly generate pseudo interrupt signals. By allowing the processor to directly generate pseudo interrupt signals, the interrupt logic can be tested without the need for routines which would ordinarily have to be run repeatedly to generate different combinations of interrupt requests.
