PURPOSE:To save I/O operating time and processing time and also to save storing areas, by reading a divisor table and a divident table only once so as to perform the division and weighted division of a related data base. CONSTITUTION:A table type data base stored in an external storage is inputted to a controller 51 through an input line 50 and the divisor and divident tables are stored in associative memories 9, 10 respectively through a data input line 1. These associative memories 9, 10 are associatively accessed, and when corresponding data are made coincie with each other, weighting calculation is performed by a processor 12 by an indication from a bit map memory 11 and the weighted result is stored in a random access memory 13. By the pipeline processing of the stored data, the related data base is retrieved. |
