Abstract

PURPOSE: To enable to use the stack freely in the subsystem, by enabling to use the existing operating system, relating to the unit having the stack at a part of the main memory.
CONSTITUTION: In case the push stack, in the instruction, BP1 designates a given R1 in GR and BP2 does R2, the content (R1) of R1 enters WR via ALU and S bus, and BP1 is controlled for +1 to designate R1+1 and control is made with (R2) by BP2 and (R1) in WR and also (R1+1) by BP1. Further, in case of pop stack, another control is made. Thus, the stack function is realized, the existing computer program, OS are used as they are to use the stack function in the unit of sub- system freely, and the new provision of instructions by it can be as less as two.
