Memory copies in hardware
That whole thing reminds me of the 82258 ADMA controller I worked with 15
years ago. It was only 16 bit at that time but it did exactly what the
article describes. It could also do transformations and scatter-gather
and all that stuff. I just put the parameters into some of it's registers
and let it go and it signalled the completion with an interrupt. Seems
like someone discovered that chip and thought that it would be a good
idea.
