A DMA control system for controlling the data transfer in the numerical controller and the like. A DMA control circuit (12) reads address data from a DMA address memory (14) storing address data, carries out the calculation, and transfers the calculated address data as a transfer address to execute the DMA control. Therefore, the DMA control is carried out even when the arrangement of the data in the sending portion and that of the data in the receiving portion are not in sequential correspondence. |
