Im sorry i was meaning to say crossbar switch. I was thinking more along the lines of an alternative pc architecture. I was reading a few weeks ago about macintosh design stories and i was suprised by how simple the designs of the early macs were and was even more surprised why it was so expensive. I thought maybe the same design principles and design tradeoffs could be applied to current technology. Instead of a bus there could be a crossbar switch.Maybe 4 or more ddr sockets, 2 processor sockets of some sort, low speed serial bus like ADB, a graphics card, an ethernet and a few high speed busses like serial scsi connected to it. Maybe it can fit all fit in a few fpga's or cpld's. -- www.smsglobal.net SMS Global Ltd Short Message Service For Seafarers _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
