ABSTRACT:
A direct memory access controller (8, FIG. 1) is provided which can service a number of input/output controllers (24, 26) concurrently on a time-division multiplexed basis. The direct memory access controller 8 (DMAC) is capable of interconnecting more than one input/output device (64, 66, 69, 74, 76) with more than one system memory (2, 20). The DMAC 8 can also transfer data from one system memory (2) to a second system memory (20), or within one system memory.
