Why not DMA
Just wondering why Intel and AMD do not use DMA. It would increase performance. Cheers Lon |

He must've come off his isolated island after something like a 20-year
stranding. DMA has been in every PC starting back in the original PC dating back to 1981 (http://www.infran.ru/TechInfo/BSD/handbook257.html). Maybe "DMA" means something to Lonald other than Direct Memory Access. Since Lonald mentions Intel and AMD instead of system manufacturers, like IBM, Dell, Gateway, Aopen, and so on, maybe he is asking why CPU chip makers haven't moved the external chipset onto the die for the CPU and made all functionality integrated into one package. Maybe .... ah, forget it. A short question like this leaves way too much for interpretation. -- __________________________________________________ _____ ** Share with others.
