Such a cpu is tiny compare to the reste of the GPU in terme of space. It offer great flexibility and provide means to correct some hardware bug and adding some feature that could be very complexe and slow in pure hardware.
I'm thinking about returning to the nanocontroller idea for VGA (and saying so-what to the massive latency for VGA reads). Some VGA stuff could possibly require specialized assist hardware, but the majority of it could be done in software. This controller could run double-duty for a number of other purposes. We would give this processor access to graphics memory and some user I/O signals, at least. VGA accesses would cause interrupts. We could also give it access to the GPU and the DMA contoller. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
