AGP is a DDR version of 66MHz PCI yes.
But the Cirrus Logic GD5446 has a PCI interface. So it's PCI unless I figure out how an FPGA can read the ram direct to bypass the PCI bus.
I should probably not actually refer to it as Picasso IV, but people know what it is.
Alpine is the name of the chip series... so mabe AlpineIV?
Getting a little off the A2630 topic though
