| Abstract: | 16 bits DMA transferring is a unique function of the IBM-PC/AT. If large quantities of data are to be acquired at high speed, it will make the most of AT's potentiality when its DMA channel is better utilized. This paper deals with the realization of the data transferring function of 16 bits DMA channel by programming and interface circuit layout. |
