Abstract

PURPOSE: To make it unnecessary to provide the starting program to the memory in the computer and then to increase the memory capacity for the program, by realizing the device to execute the order through the fixed address, i.e., the starting device for the initial program loader.
CONSTITUTION: To srart the initial program loader, signal IPL is produced by the keyboard operation, and AND circuit 71 is turned on by signal IPL and operation signal CK to deliver the start order signal. In other words, the order signal gnerator is constituted with the IPL key and AND71. OR circuit 73 resets program counter PC64 via power making detection signal ON. At the same time, AND76 supplies the output signal of PC64 to reset FF75, and FF78 is reset by operation signal R and AND72 to deliver the NOP signal. The count value of PC64 resets FF75 in the fetch cycle of the order, and then the different order is set to register 61. Thus, the initial program loader is started
