Abstract: According to one embodiment of the present invention, a system (10) for data transfer is disclosed that comprises a transfer memory (24) having one or more buffers (40, 42, 44, 46, and 48). Accessing units comprising direct memory access units (20 and 22) are coupled to the transfer memory (24) and are operable to access the transfer memory (24). Pointers (50, 52, and 54) stored in the transfer memory (24) direct the accessing units (20 and 22) to selected ones of the buffers (44, 46, and 48) such that no two accessing units (20 and 22) are simultaneously accessing one buffer (44, 46, and 48). More specifically, the pointers (50, 52, and 54) may also direct a memory control unit (30) to a buffer that is not being accessed by an accessing units (20 and 22). According to one embodiment of the present invention, a method for data transfer is disclosed. First, a transfer memory (24) comprising one or more buffers (40, 42, 44, 46, and 48) is provided.
