- If I have a look at A3000+ I fully agree...the job was almost done using the
- DMAC...a nice DSP-System with direct memory access...
-
- But if they move to PPCP the complete PPCP chipset is already available and
- such things might be a little more difficult to integrate.
- On the other side they could do a PCI AGA-Board with additional DSP...
- and would be able to offer it for other systems very easy.
