PCIe interface

Matrox Morphis QxT allows the transfer of live video to Host memory. Matrox
Morphis QxT features an on-board 64-bit 133 MHz PCI-X bus master to reduce
CPU usage. The data is then transformed to PCIe before being transferred to the
Host over the Host PCIe bus. Matrox Morphis QxT has a x4 PCIe bus interface.
