Abstract
PURPOSE: To give a check to the contents written into the control memory, by having a comparison instruction of the contents between the main memory and the control memory in case the microprogram is controlled by the rewriting enable control memory.
CONSTITUTION: The comparison step for the data contents between the main memory 1 and the rewriting enable control memory 2 is started by storing the designated address of the necessary data within the memory 1 and the designated address of the necessary data within the control memory 2 into the register 10 and the counter 4 each and then storing the data of the main memory into the reading register 13. The data of the register 13 is stored in the register file 17 in the route passing through the gates 15, 9 and 18 each, and the data of the memory 2 is applied to the comparator 14 through the gate 8. Then the data stored into the file 17 is applied to the comparator 14. Thus a comparison is given to the contents between the both data.
