Abstract

PURPOSE:To prevent the annihilation of an interruption to a central processing equipment, by executing an error processing microprogram when an error of the control memory has been detected, in data processing equipment of a microprogram control system. CONSTITUTION:A control memory is accessed by the contents which have been sent out from the control part and have been set to an address register 1, and when an error exists in the read-out information, a parity checking circuit detects it, sets a prescribed value to the upper rank part of the address register 1, also controls a switching circuit, and an output information of an auxiliary control memroy 7 is selected, and is sent out to a memory register 5. A micro-instruction which has been set to the memory register 5 controls an operating circuit 6, and generates an interruption,etc. to the central processing a equipment or controls reloading of a microprogram from an external equipment.
