Abstract

PURPOSE: To make it possible to execute a subroutine easily by a microprocessor with no stack pointer, by providing a work register stored with a subroutine parameter.
CONSTITUTION: Work register 8 or 9 is connected to logical operation circuit 2 via S bus 10. As for the execution of a subroutine, a parameter is written to work registers 8 or 9 to execute the subroutine and at the subroutine side, arithmetic is carried out on the basis of the contents of the work register and its result is stored in the register before resetting. Consequently, a stack pointer and its control hardware are unneeded and the need for the calculation through the subroutine as to the stack pointer can be eliminated.
