Interesting...
64bit PCI * 66Mhz = 4,429,185,024 bit/S = 4,244 Mbit/S
= 528MB/S ...burst rate. Sustained rate is about half that,
so the ballpark is: 2,122 Mbit/S = 264 MB/S.
Assuming "400Mb" is "400Mbit", you will be at most able to
process a total of 5 channels worth of data simultaneously.
If that's "400MB", well, expect to get only 2/3 of a single
channel, or burst, up to 1 1/3 channels...
