摘要: An apparatus and method for prioritizing interrupt requests in a RISC processor. By utilizing hardware to prioritize the requests, processor time is reduced. The acknowledge signal from a priority resolve circuit selects the given service routine entry to branch instruction generating circuit. A lower priority service routine can be interrupted by a higher priority request.
