Abstract
PURPOSE: To simplify the constitution and to make the size small by selecting the buffer and introducing the application program of external memory to the main memory through the initial program introduced to the memory, in the computer having the volatile main memory.
CONSTITUTION: The decision circuit 15 determines the selection of either buffer of the buffer 13 linked to the address terminal of the main memory 3 or the bus buffer 14 linked to the address terminal of the initial program loader 6. On the other hand, the alteration circuit 16 changes the status of the circuit 15 with the address output to the loader 6 from the buffer 14. Further, at the application of power supply, the circuit 15 selects the buffer 14, introduces it to the memory 3, and when the introduction of the initial program is finished, the curcuit 16 is operated to change the status of the circuit 15, the buffer 13 is selected and the application program in the external memory 4 is introduced to the memory 3 with the initial program introduced to the memory 3. Thus, the initial program is automatically loaded to the memory 3 to simplify the constitution and to make the size small.
