Abstract

PURPOSE:To handle the first control memory section and the second control memory section in the same level, by commonly making the address control to the 1st control memory section consisting of a fixed memory unit and the 2nd control memory section consisting of erasable memories. CONSTITUTION:Taking that the extended user instruction designating the microprogram in the 2nd control memory section 9 is read out from the main memory 1. This extended user instruction is stored in the instruction register 2. The data of instruction code of the extended user instruction stored in the instruction register 2 is given to the 1st control memory section 8 at the micro address via the gate 3, multiplexer 5 and driver 6 in order. Similarly, the data in the instruction code is given to the 2nd control memory section 9 via the gate 3, multiplexers 5, 15 and driver 7 in order. Micro instruction is read out with the micro address.
