PROBLEM TO BE SOLVED: To provide a technology of reducing latency of data transfer between a plurality of processing systems, when applications cooperate with each other in the processing systems.SOLUTION: A processing system 700 includes: a GPU 724 for generating a video; a memory 726 for storing data; a GPU data bus 718 for connecting the GPU 724 and the memory 726 to each other; a DMA controller 716 connecting to the GPU data bus 718; an input/output bridge 722 connecting to the GPU data bus 718, and connecting also to an external bus for transmitting/receiving data to/from an external processing system 700 which cooperates with the processing system 700; and a CPU 710 which shares data stored in a memory 726, with the GPU 724. The GPU 724 issues an instruction to the DMA controller 716 to transfer data stored in the memory 726, without using the CPU 710. |
