Abstract
PURPOSE:To easily cope with a design change, etc. by controlling and realizing a loading operation of a micro-instruction to a first control memory, by using a microprogram held in a second control memory. CONSTITUTION:When a micro-instruction to be executed is not held on the first control memory 2, outputs of a comparator 4 are discordant and a start micro-logical address of a microprogram held in a second control memory 7 is supplied to a second register 6. When the second register 6 holds this start micro-logical address, the head micro-instruction of the microprogram is read out of the second control memory 7, and a series of micro-instructions are executed. In such a case, a loading circuit 9 is controlled by execution of the microprogram held in the second control memory 7, a real address on a main storage device 5 in which a micro-instruction corresponding to a micro-logical address held in a first register 1 is stored is derived, and by this address, the micro-instruction corresponding to the micro-logical address is read out, and written to a first control register 2.
