Invention: DMA controller comprising bus switching means for connecting data bus signals with other data bus signals without process or intervention

Year	Description
1992	Invention patented by Takashi Miyamori on May 14th, 1992. Abstract: A DMA controller, has bus switching means for connecting certain data bus signals with other data bus signals by itself during the DMA bus cycle. Therefore, even if the data bus signals in which a memory is connected are different from the data bus signals in which an I/O device is connected, these data bus signals can be connected with each other through said bus switching means, without using an external bus switching device.
