30 Chapter 3: Using multiple Matrox Radient eCL boards
Installation of multiple boards
You can install and use multiple Matrox Radient eCL boards in one computer.
Install each additional Matrox Radient eCL board as you installed the first board
(refer to
Chapter 2: Hardware installation ). The number of Matrox Radient eCL
boards that you can install is primarily dependent on the number of physical slots
in your computer and your BIOS; your BIOS establishes how many PCI devices
can be mapped to the PCI memory space of your computer.
Using MIL-Lite, you have to allocate a MIL system for each board and allocate
the resources of each MIL system. For more information, see
MsysAlloc() with
M_SYSTEM_RADIENT in the MIL Reference.
Simultaneous image capture from different
boards
Besides simultaneously capturing images from multiple video sources attached to
a Matrox Radient eCL board (except eCL-SF), you can simultaneously capture
images from video sources attached to different Matrox Radient eCL boards.
However, the number of video sources from which you can simultaneously capture
images is computer-dependent.
The use of a high performance PCIe chipset is necessary to sustain PCIe transfers
to Host memory. The list of platforms that are known to be compatible with
Matrox Radient eCL are available on the Matrox web site, under the board’s
compatibility list.
To measure the effective, available bandwidth of the PCIe interface used by your
Matrox Radient eCL board, you can use the RadientBench tool integrated in the
MILConfig utility. As a reference point, capturing from a 2K x 2K, 8-bit,
60 frames/sec video source will require a minimum bandwidth of 240 Mbytes/sec,
plus an additional bandwidth margin of approximately 20%, for a bandwidth of
288 Mbytes/sec.
