Abstract: A digital signal processor includes a byte direct memory access (DMA) controller and an external memory controller, both of which are coupled to each other. The external memory controller is coupled to a byte memory and other external memories through a common data bus. The byte DMA controller performs a byte DMA operation to the byte memory through the common data bus by controlling the external memory, thereby avoiding an additional data bus. As a result, the digital signal processor according to the present invention has less connecting terminals and achieves a size reduction.
