ABSTRACT:
A data processor comprises a plurality of registers 1 (registers a to d), a plurality of data saving stack memory devices 2 coupled to the registers 1 for exclusive use thereof, respectively, and an instruction decoder for decoding instructions for controlling the registers 1 and the data saving stack memory devices 2 in accordance with the result of the instruction decoding. In response to an instruction "PUSH", the contents of the registers 1 (registers a to d) are selectively saved to the data saving stack memory device 2. In response to a instruction "POP", the contents of the data saving stack memory devices 2 are selectively restored to the registers 1 (registers a to d). Each of the instructions "PUSH" and "POP" has a field for indicating need or needlessness of the saving and restoration for each of the registers 1 and each of the data saving memories 2.
