Abstract

PURPOSE: To secure a quick tracing for the program progress with reduced amount of the hardware for the microprogram control type information processor by discontinuing or continuing the order execution with every execution of the microorder.
CONSTITUTION: Microprogram storage circuit 1 stores the microprogram; address selection circuit 7 generates the address of circuit 1; and output register 2 stores the microorder read out from circuit 1. In addition, branch microorder detection circuit 8 detects that the microorder stored in register 2 is the branch order. Besides these circuits and register, arithmetic circuit 3 is provided to calculate the branch conditions when the microorder stored in register 2 is the branch order, along with branch condition decision circuit 4 which decides whether the branching is given from branch control field 23 of register 2 with every operation at circuit 3. Thus, branch address field 22 of register 2 is selected when the branch conditions are satisfied, and the output of address register 6 is selected when the conditions are not satisfied respectively.
