<p>A direct memory access system consists of a direct memory access controller (116) establishing a direct memory access data channel and including a first interface for coupling to a memory. A second interface is for coupling to a plurality of nodes. And a processor (106) is coupled to the direct memory access controller (116) and coupled to the second interface, wherein the processor configures the direct memory access data channel to transfer data between a programmably selectable respective one or more of the plurality of nodes and the memory (104 or 108). In some embodiments, the plurality of nodes are a digital signal processor memory and a host processor memory of a multi-media processor platform (100) to be implemented in a wireless multi-media handheld telephone.</p> |
