Hello to everybody.
We are testing some hardware that performs some calculations in hardware.
The hardware is a PCI board plugged on an ordinary PCI slot.
Although the hardware does a reasonable work in terms of speed at performing the pure calculation, we have realized that the PCI Bus maximum speed is a huge bottleneck when streaming data and from the PCI board.
My question is simple: which is the best approach to deal with a PCI board in order to support the maximum data transfer speed. Note that we are open to use any PCI board (even PCI-X boards,…).
Any suggestion is welcome.

Long burst cycles. One of my cards can transfer more than 80 megabytes/sec
without any problem. The max is about 100 megabytes/sec if using 64 cycle
burst. (32bit, 33MHz PCI)
