PROBLEM TO BE SOLVED: To increase the information processing efficiency of a multiprocessor system. SOLUTION: An information processing device 1000 comprises a main processor 200 for centrally controlling the entire device, a graphics processor 100 for performing image processing computations, and a main memory 50. The information processing device 1000 further comprises a DMA controller 28 for controlling simultaneous transfer of m (m is an m>1 integer) data, the main memory 50 where data for specific processing is expanded first, and buffers 12 in a set of n (n is an n>m integer) for storing the data transferred from the main memory 50. In the simultaneous transfer of a plurality of data, a first buffer of the set of buffers 12 is set as one data destination and a second buffer is set as the other data destination.
