<p>PROBLEM TO BE SOLVED: To store respective unit data constituting retrieval data in respective blocks of a register, and when the storing order of unit data in the blocks is different in each retrieval data, to quickly retrieve data to be retrieved from a retrieving table based on the stored retrieval data. SOLUTION: The retrieving circuit is provided with selectors 31 to 34 for inputting respective unit data in respective blocks of a register 11 in common, a selection circuit 35 for controlling a selector so that respective unit data inputted to respective selectors 31 to 34 corresponding to respective blocks in the retrieving table 12 and a register 36 for storing the specified information of respective blocks of the register 11 in relation with inputted retrieval data. The selection circuit 35 inputs the specified information stored in the register 36 in each storage of retrieval data in each block of the register 11, controls the switching of respective selectors and allows each block of the register 11 to correspond to each block of the retrieving table 12 at the rate of one to one.</p> |
