PURPOSE:To classify and store a data when transferring it to a storage device, by dividing a data into groups by executing association processing by a data value, and storing the data by each group, when storing the data in the storage device. CONSTITUTION:From a secondary storage device 5, transfer of a data train 4 to be classified is started, and a data inputted to a classifying storage device 10 is latched by a data part of a data latching circuit 9. At the same time, it is inputted to a separating circuit 7, is converted to a separating code, is decoded by an address controlling circuit 8, and a pointer value of a group corresponding to a classifying code is latched by a pointer part of the low rank of the data latching circuit 9. Subsequently, contents of an address register are inputted to a storage device 2 as an address input, and contents of the data latch 9 are latched.In this way, classification of a data is executed when the data is transferred between the memories. |
