DMA control device controlling sequential storage of data

Year	Description
1994	Invention patented by Takashi Yamasaki on September 5th, 1994. Abstract: A DMA transfer of 8-bit units and 16-bit units can be performed regardless of the proceeding direction of the address and whether the first address to be accessed is even or odd. In a conventional DMA transfer, the DMA control device required a function for selecting 8-bit configuration or 16-bit configuration of transfer data when the proceeding directions of addresses at the transfer source and transfer destination were different. The present invention reverses a determined result and indicates whether the first address to be transferred is even or odd, when the proceeding direction of the address is "reverse" and the data has a 16-bit configuration.
