Simultaneous image capture from different boards 47
The use of a high performance PCIe/PCI/PCI-X core-logic chipset is necessary
to sustain PCIe/PCI/PCI-X transfers to Host memory. If a high performance
chipset and a 133 MHz 64-bit PCI-X slot is used with Matrox Solios XCL and
XA, you should not have a problem with dropped frames. The list of platforms
that are known to be compatible with Matrox Solios are available on the Matrox
web site, under the board’s compatibility list.
To measure the available bandwidth of the PCIe/PCI/PCI-X segment used by
your Matrox Solios board, you can use the SoliosBench tool integrated in the
MILConfig utility. As a reference point, capturing from a 1K x 1K, 8-bit,
60 frames/sec video source will require a minimum bandwidth of 63 Mbytes/sec,
plus an additional bandwidth margin of approximately 20%, for a bandwidth of
75 Mbytes/sec.
