ABSTRACT
Five solutions to the precise interrupt problem in pipelined processors are described and evaluated. An interrupt is precise if the saved process state corresponds to a sequential model of program execution in which one instruction completes before the next begins. In a pipelined processor, precise interrupts are difficult to implement because an instruction may be initiated before its predeces
