Abstract
PURPOSE:To reduce the processing value of a central controller by making this controller set only an address pointer register, a comparison data register and a search counter register. CONSTITUTION:A central controller CC2 writes an address into an address pointer register 3 to instruct a specific address where the retrieval of data is started. Then the CC2 writes the data into a comparison data register 5 to instruct the number of existing circuits and then the data into a search counter register 7 to instruct the number of retrieving actions. Then a retrieval failure report register 10 or a retrieval success report register 9 is looked in periodically to wait for the turn-on state of either one of both registers 9 and 10. Thus the processing value of the CC2 is reduced and therefore the short of the processing capacity of the CC2 is never caused.
