DATA STORAGE DEVICE, DATA STORAGE CONTROL DEVICE, DATA STORAGE CONTROL METHOD AND DATA STORAGE CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To perform simultaneous read of a plurality of desired data by storing all data in a memory composed of a plurality of memory banks without applying a load to hardware.;SOLUTION: This device comprises a memory control means including a data storage control part 20, a data read control part 30 and a data transfer control part 40. The memory control means determines, at the time of successively sorting and storing all data in a plurality of memory banks constituting the memory, whether or not the data to be stored are data of a position corresponding to an access pattern, based on the access pattern showing a plurality of desired data to be simultaneously read, skips the memory bank to store the data by incrementing the bank address, in case that they are the data in the position corresponding to the access pattern, and stores the data of the position corresponding to the access pattern in a memory bank with the incremented bank address, whereby all the data of the position corresponding to the access pattern are sorted and stored in different bank memories, and a control for simultaneously reading a plurality of desired data from the memory 10 is performed.;COPYRIGHT: (C)2005,JPO&NCIPI
