Abstract
PURPOSE: To make it easy to multiply subroutines by storing return addresses of subroutines in a scratch memory which can be addressed corresponding to the processing level of a microprogram.
CONSTITUTION: Microprogram processing level control circuit 100 and microprogram executing circuit 102 are connected together via processing level indication line 1001. control circuit 100 and scratch pad memory address register 104 are also connected via signal line 1002. Memory 101 is connected to register 104 via address line 1003 and further to register 105 via data line 1004. Register 105 is connected to register 106, memory 103 is connected to registers 105 and 106, and register 107 is connected to program executing circuit 102; and return addresses of subroutines are stored in a scratch pad memory which can be addressed corresponding to the processing level of a microprogram, so that subroutine can be multiplied.
