- Looks ok there, although there would be a lot of situations where the
- 68030 will run out of cache memory and will stall waiting for the DMA
- to finish. I guess that someone has to do actual performance benchmarks.
-
- Also what we need to determine how likely will the 68030 stall is
- how many cycles it takes for the DMA stuff to take place for bytes moved
- to RAM.
