PCI bandwidth requirements
Sustained PCI-transfers to memory require the use of a high
performance PCI core-logic chipset, such as the Intel 430TX or
440LX. If a high performance chipset is used, you should not
have any PCI bandwidth problems grabbing two full-sized
images simultaneously from two Matrox Meteor boards in real
time. However, grabbing more than two images
simultaneously might result in PCI bandwidth problems.
For example, grabbing one full-sized NTSC or PAL image in
real time will require a PCI bandwidth of 35 MBytes/sec. or 42
MBytes/sec., respectively.
When grabbing from three or more Matrox Meteors
simultaneously, you will have to reduce the image size to avoid
reaching the upper limits of the overall available bandwidth.
