Abstract

PURPOSE:To prevent the device from malfunctioning, by providing it with a means which makes the micro instruction start address, which is designated once by the advance control device, ineffective and instructs to set the address again, in the pipleline type information processing device. CONSTITUTION:Advance control device 1 reads out instructions and operands from memory device 3 and transmits micro mu instruction address ICSA to operating device 2 through signal lines 13-15 for the purpose of operating mu program PR required for the operation. Device 2 has control storage CS where muPR is stored, and the operand from device 1 is set to a prescribed work register of device 2. Device 2 executes a prescribed processing on a basis of ICSA and sends end signal EOP to device 1 at the processing end time. In case of the advanced control of the branch instruction in device 1, if the failure of advanced forecasting is detected, this detection signal is received to make the mu instruction start address, which is designated once, ineffective, and ICSA is set again, and the retransmission instruction of ICSA is generated on signal line 13.
