Abstract
A DMA system includes at lease one read bus, at least one write bus, at least one buffer memory bus, and a DMA controller. The DMA controller comprises a plurality of channels and a bus arbiter. The channels are electrically connected to the read bus, the write bus, and the buffer memory bus. A source address and a destination address of data for each channel are assigned by a control table. The bus arbiter performs bus arbitration and prioritizes data access among the read bus, the write bus, and the buffer memory bus.
