Abstract

PURPOSE:To reduce the consumption power for chip driving by causing a storage device to perform processings from the search processing for index pattern collation up to the read/write processing on the storage device while updating addresses autonomically. CONSTITUTION:Storage device 1 where index pattern data are stored at start adresses of plural word unit data is provided with collation circuit 9, coincidence reporting circuit 10, and address counting-up circuit 11, and contents of an address register are updated by address counting-up circuit 11 during the search processing; and when collation circuit 9 detects the agreement between contents of collating index pattern register 8 and read-out index pattern data, reading/writing is performed from contents of the address register at that time on a basis of address counting-up circuit 11 without waiting for the instruction from upper-level control unit 2.
