KZNerd, regarding "muxing" data over narrow interfaces: Did you know that Intel is already going in this direction? How would you explain HubLink, the interface between the north and south bridges of Intel's 800-series of chipsets? It's only 8 bits wide, but it runs at 266 MHz for a maximum bandwidth of 266 MB/sec. No longer is the PCI bus in between the north and south bridges; it's now hanging off the south bridge. So if you trace traffic from PCI to memory, you'll find data first moving over a 32-bit PCI bus, then squeezed into an 8-bit HubLink port, then expanded out to the 16-bit Rambus interface, and finally expanded to 16 bytes inside the RDRAM device. Sounds insane, doesn't it? Tenchusatsu
