Abstract

PURPOSE: To reduce the number of the control circuit, the address comparator and other peripheral circuits with use of one buffer memory by dividing the inside of the buffer memory by addresses and controlling the divided parts according to each using purpose, and thus to ensure the effective use of the memory element.
CONSTITUTION: In the information processor which possesses the buffer memory accompained to the processor to hold the partial copy of the data memorized in the main memory, address register 200 to decide the character or the type of the memory access is provided along with address comparator 203 and 204 plus directory part 206 which uses the output of circuit 204 as the input. Thus, the output of part 206 is compared through comparators 207-1W207-4 at the access of the buffer memory. According to the comparison result, the address of the buffer memory is altered at data part 209. Thus, one buffer memory is used as plural units of buffer memories for different purposes.
