PURPOSE:To increase the processing efficiency, by comparing the distance between data read out from the data of two or more dimensions and writing it in to the buffer memory only when it is less than the reference value. CONSTITUTION:Data a1-an are read out from the data(array data) A1-An of two or more dimensions in the main memory 3, and they are fed to the processor 1 and the buffer memory 2. Further, in writing it in the memory 2, the distances D1, D2, D3-, among the data a1-an are respectively compared with the predetermined reference value Ds, and only when these values are less than the reference value, the switch 16 is made to connected state and stored in the memory 2. Further, in case of the reference value or more, no write-in is made to the memory 2. Thus, in the data processing of two or more dimension, the usage efficiency of buffer memory can be increased and the processing efficiency can be increased. |
