PROBLEM TO BE SOLVED: To obtain a DSP card that executes efficient data transfer without impairing signal processing performance of each DSP and the entire DSPs, and further to obtain a data transfer method.SOLUTION: First of all, a DSP card collectively sets a plurality of pieces of transfer control information serving as transfer conditions of data to a register inside a DMAC correspondingly to each of a plurality of DSPs of a transfer destination when dividing the large-scale and large-amount data of a processing object temporarily stored in an external storage device provided outside the DSPs for performing processing thereof by the plurality of DSPs and performing DMA transfer of the data to an internal memory of each of the plurality of DSPs. Further, the DSP card executes predetermined signal processing by each of the DSPs after completion of sequentially consecutive data transfer while sequentially and consecutively executing the data transfer by subsequent transfer control information specified by subsequent transfer command information provided in each of the plurality of pieces of transfer control information when the data transfer is started and the data transfer to one DSP is completed. |
