In this paper, we have proposed a design and implementation of an AMBA based advanced DMA controller. The DMAC has 6 channels which support hardware triggers, linking operation and channel chaining transfer and provides three dimensions transmission by parameter sets so as to perform data block moving, data sorting and sub-frame extraction of various data structures. Channel arbitration mechanism adopts hardware priority. Moreover the DMAC supports incrementing and wrapping addressing modes and completes data transfer which the data width of read and write is different by asymmetric asynchronous FIFO. And the DMAC could adopt buffer and non-buffer data transfer mode according to the speed of equipment. Experimental results show that the DMAC has better performance than traditional DMAC and DMA PL081.
