Abstract
PURPOSE: To increase the capacity of the control memory by maintaining a new instruction on the main memory and writing it sutomatically on the control memroy as occasion demands.
CONSTITUTION: In case the memory 2 is addressed, and the field which selects the format of the read word is "1", the field addresses the memory 4 which maintains the instruction code. The instruction code and the code of the register 3 storing the instruction code register are compared with the comparator 5, in case they do not conform, the main memory 9 is accessed by the main memory access circuit 8, the main memory information is read, the micro-program which is maintained is written in the control memory 16. Thus the control memory can be rewriteen automatically and can be utilized effectively by judging if the program by the instruction is in the control memory or not at that moment, and controlling the device.
