ABSTRACT:
An auxiliary interrupt control circuit is for use in a computer system including at least one peripheral for generating interrupt requests, an interrupt pending register for storing the interrupt requests, a microprocessor for processing interrupts, and an interrupt control circuit associated with the microprocessor. The auxiliary control circuit may include an auxiliary register coupled to the priority interrupt register for storing a copy of the interrupt requests. It may further include an encoder coupled to the auxiliary register and the microprocessor for generating a bit string identifying an active bit stored in the auxiliary register corresponding to a highest priority interrupt request to be processed, and for providing the bit string to the microprocessor.
