Invention: DMA controller having a plurality of DMA channels each having multiple register sets storing different information controlling respective data transfer

Year	Description
1994	Invention patented by Michael J. Bowes and Brian A. Childers on January 27th, 1994. Abstract: A direct memory access (DMA) controller is connected with the CPU bus of a computer system through a bus interface and also to an I/O bus, which is connectable to one or more I/O controllers. The DMA controller contains multiple channels, each corresponding to a particular I/O controller, which are coupled to both the bus interface and the I/O bus. Each of the channels contains at least one register set storing information for the transfer and a data buffer holding the data during a transfer between the I/O bus and the CPU bus.
