[comp.sys.ibm.pc] DMA on 386 Machines

aras@ecerl2.ncsu.edu (10/07/89)

We are working on an interfacing project which requires a very *fast*
interface to a 386 based machine. The application essentially down loads
x-y coordinates of points detected during a video scan.

Our camera system generates these points and puts them in a FIFO. From
there, we would like to down load to a 386 machine via DMA.

Most of the machines in the market seem to NOT have a DMA chip on board.
Does anyone have any info on 386 machines using a DMA chip , or even
better, any boards using the intel 82380 High speed DMA?

Any help is very much appreciated
