Abstract

PURPOSE:To realize the program control in a high speed for an information processor of microprogram system, by setting the branching address to a microprogram counter in case the signal showing the satisfaction of conditions is obtained. CONSTITUTION:An oscillating circuit 44 produces a clock pulse CP having a shorter period than that of the read clock that prescribes the machine cycle of device. In case the instruction of a microprogram shows a branch type, the pulse CP is applied to a microprogram counter 41 in place of the read clock. Based on this pulse CP, the branching address is set to the counter 41.
