I was (somewhat) following a dicussion about high speed communications handled over the PCI bus, and there's a company that makes T1/T3-level serial cards for PC's, and from what they were saying, there's no way to reach even a full T3 worth of bandwidth on a PCI bus,
PCI is 33mhz at 32bits = about a gigabit per second. Fast PCI is 66mhz, and a fast 64bit PCI standard is coming, which yields 4Gbps across the bus. Now, admittedly, you can't get that fully -- but if you claim you can't get a mere 45mbps across the bus per second you are doing something desperately wrong and stupid, like making the main CPU deal with *way* too much of the work. Of course, most serial communications companies ARE doing things desperately wrong and stupid, but that another story... Perry
