Abstract
PURPOSE: To facilitate both the development of program and its storage into the main memory, by performing these actions via the program control memory including the machine word and the microorder.
CONSTITUTION: The machine word 12 is designated by the memory address register MAR16 of the main memory 11 to be stored in the memory data register MDR20 through the AND circuit 18 and then executed to set the FF17. With this action, the circuit 18 and the AND circuit 19 become nonconductive and conductive each. When the MAR 16 designates the next address, the microorder 14 read next is stored in the intermediate register 21 via the circuit 19 and then stored in the storage data register 22 to be executed. After this several microorders are executed through the control memory, and then the final microorder 15 is executed. Thus the circuits 18 and 19 are turned conductive and nonconductive respectively to secure a reset to the original state. As a result, both the development of program and its storage into the main memory can be facilitated.
