摘要：A RISC type microprocessor for implementing multi-stage pipeline processing.The RISC type microprocessor includes mode allocating means, interrupt controllingmeans and a jump instruction table. The mode allocating means is used for allocating a

first mode for cyclically executing processes corresponding to a plurality of interrupts atpredetermined intervals or a second mode for successively executing the processescorresponding to the interrupts. The interrupt controlling means is used for controllingthe interrupts corresponding to the mode allocated by the mode allocating means, andis operable to save particular information to a stack upon occurrence of an interrupt andto fetch the particular information from the stack upon completion of the interruptprocess. The jump instruction table is used in processing interrupts without stopping themulti-stage pipeline processing.
