Processing capabilities
Matrox RadientPro CL features an on-board real-time processing FPGA device,
which can be configured to offload and even accelerate the most
compute-intensive part of typical image processing applications, without
generating additional data traffic within the host computer (Host).
Processing FPGA The Processing FPGA on Matrox RadientPro CL is a highly customizable Altera
Stratix V FPGA. The operations performed on-board are controlled using the
Matrox Imaging Library (MIL) application development software. Using MIL,
the processing units (PUs) of an FPGA configuration can be rearranged to perform
the operations in the required sequence, without having to necessarily generate a
new FPGA configuration. When the need arises, Matroxs FPGA design services
can be employed to generate an application-specific FPGA configuration.
Before the Processing FPGA can process grabbed images, they must be stor
ed in
main on-board
memory. If images stored in Host memory are required, they can
be streamed directly to the Processing FPGA for processing. Images resulting from
Processing FPGA processing can be stored in main on-board memory or streamed
to the Host.
On-board acquisition and processing memory
Matrox RadientPro CL has two types of on-board memory: main on-board
memory and dedicated Processing FPGA memory (optional).
Main on-board memory is used to store acquired images, and images for or
resulting from processing. As main on-boar
d memory, Matrox RadientPro CL is
equipped with 2 Gbytes of DDR3 SDRAM. Main on-board memory is accessed
through the memory controller of the Processing FPGA. The memory controller
has multiple input ports and a data transfer rate of up to 12.8 Gbytes/sec.
Matrox RadientPro CL can optionally feature dedicated Processing FPGA
memory to store
intermediate data while the Processing FPGA performs
operation. As Processing FPGA memory, Matrox RadientPro CL uses 4 banks of
QDR-II SRAM that total 16 or 32 Mbytes of memory and have a total transfer
rate of up to 4.0 Gbytes/sec in each direction.
Matrox RadientPro CL 11
Additional functionality
In addition to the core video capture and processing capabilities,
Matrox Radient Pro incorporates a variety of features to simplify overall system
integration. These
features include:
LVDS-compatible serial interfaces. Each interface is mapped as a
COM port so
that it can be accessed through the Microsoft Windows API. The serial interface
can both receive and transmit signals, in full-duplex (bidirectional) mode.
Color space converter and pixel formatter. These can convert captured or
processed data as it is being transferred to the Host. They can convert 8- or 16-bit
monochrome or 24- or 48-bit packed BGR data to monochrome, packed BGR,
packed BGRa, planar RGB, or YUV (YUYV) format. In addition, they can flip,
crop, or subsample data sent to the Host.
Bayer decoder. This can convert Bayer-encoded data to RGB. The following Bayer
patterns are supported: GRBG, GBRG, BGGR, and RGGB.
Auxiliary, multi-purpose signals. These are non-video signals that can support
one or more functionalities depending on the auxiliary signal (for example, trigger
input or timer output). Matrox RadientPro CL has eight auxiliary signals: 3 TTL
auxiliary I/O signals, 2 LVDS auxiliary input signals, 1 LVDS auxiliary output
signal and 2 opto-isolated auxiliary input signals. Installing the optional adapter
bracket will allow you to access an additional eight of these auxiliary signals.
Integrated rotary decoders. These can decode quadrature input received from a
rotary encoder.
Data transfer
Under optimum conditions, Matrox RadientPro CL can exchange data with the
Host at a peak transfer rate of up to 3.2 Gbytes/sec. Optimum conditions include
using the board in a PCIe 2.x slot with 8 active lanes, using a 256-byte payload.
DMA read and write per
formances are chipset and computer dependent, and are
slightly affected by the image size and alignment in Host memory (frame start
address and line pitch).
12 Chapter 1: Introduction
Software
To operate Matrox RadientPro CL, you can use one or more Matrox Imaging
software products that supports the board. These are the Matrox Imaging Library
(MIL) and its derivatives (for example, MIL-Lite and Matrox Intellicam). All
Matrox software is supported under Windows; MIL is also supported under Linux
when using Matrox RadientPro CL. Consult your software manual for supported
versions of these operating systems.
MIL MIL is a high-level programming library with an extensive set of optimized
functions for image capture, processing, analysis, transfer, compression, display,
and archiving. Image processing operations include point-to-point, statistical,
spatial filtering, morphological, geometric transformation, and FFT operations.
Analysis operations support camera calibration, are performed with sub-pixel
accuracy, and include pattern recognition (normalized grayscale correlation and
Geometric Model Finder), blob analysis, edge extraction and analysis,
measurement, image registration, metrology, character recognition
(template-based and feature-based), code recognition and verification (1D, 2D,
and composite code types), bead inspection, 3D reconstruction and analysis, and
color analysis.
MIL applications are easily ported to new Matrox hardware platforms and can be
designed to take advantage of multi-processing and multi-threading
envir
onments.
MIL-Lite MIL-Lite is a subset of MIL. It includes all the MIL functions for image
acquisition, transfer, display control, and archiving. It also allows you to perform
processing operations that are typically useful to pre-process grabbed images.
Matrox Intellicam Matrox Intellicam is an interactive Windows program that allows for fast video
source interfacing and provides interactive access to all the acquisition features of
your Matrox board. Matrox Intellicam also has the ability to create custom digitizer
configuration format (DCF) files, which MIL and its derivatives use to interface
to specific non-standard video sources. Matrox Intellicam is included with all
Matrox Imaging software products.

This chapter explains how to install your
Matrox RadientPro CL board in your computer.
18 Chapter 2: Hardware installation
Installing your Matrox RadientPro CL board
Before you install your Matrox RadientPro CL board, some precautionary
measures must be taken. Turn off the power to your computer and its peripherals,
and drain static electricity from your body (by touching a metal part of the
computer chassis).
Important Note that your
board should be installed before you install your software.
Proceed with the following steps to install your board:
1. Remove the cover from your computer; refer to your computers documentation
for instructions.
2. Check that you have an empty x8 (or x16) PCIe 1.x or 2.x slot in which to install
your Matrox RadientPro CL
*
. Note that a PCIe 2.x slot will ensure the fastest
possible transfer of data to the Host.
*. Note that you can also install Matrox RadientPro CL in a x4 PCIe slot that has a
mechanical x8 connector; however, the maximum transfer rate between
Matrox RadientPro CL and the Host is reduced by 50%.

Installing your Matrox RadientPro CL board 19
Matrox RadientPro CL might drop frames if there are not at least 8 active lanes
on the PCIe connector to the Host (for example, if the board is connected to a x8
PCIe connector that has only four active lanes
*
). Verify with your motherboard
manufacturer to find out whether your motherboard works efficiently with a x8
PCIe boar
d, such as Matrox RadientPro CL.
If you need to install the cable adapter bracket of your Matrox RadientPro CL
board, you need an additional slot. This
slot need not be adjacent to the Matrox
RadientPro CL board. In addition, the cable adapter bracket does not plug into
the slot’s connector; it attaches only to the back of the computer’s chassis.
Note that the external auxiliary I/O connectors on the cable adapter bracket
are panel mount connectors. So if you dont want to occupy an entire slot to
access the two connectors, you can punch out two holes in the computer chassis
for these connectors, and then screw the connectors in the holes.
3. If there is a metal plate at the back of the selected slots, remove them. Keep the
screw from the top of the plates to anchor your board and cable adapter bracket
once they are installed.
4. Position your Matrox RadientPro CL board in the selected slot(s), and then press
the board firmly but carefully into the connector of the slot.
*. After installing the board, you can verify in software the number of PCIe lanes that are
currently active using the MIL-Lite function MsysInquire() with
M_PCIE_NUMBER_OF_LANES.
20 Chapter 2: Hardware installation
Important When installing your Matrox RadientPro CL board in a x16 PCIe slot, special
care must be taken to avoid damaging the board. Some x16 PCIe slots have a
connector with a retainer. Matrox RadientPro CL must not come into contact
with the latch of this retainer.
The PCIe specification does not define appropriate keep-out regions for the latch
to provide any tolerance to tilting or rotation when inserting or removing add-in
boards in these connectors. Therefore, do not tilt the Matrox RadientPro CL board
backwards or rotate it when installing it; otherwise, the board might touch the
latch and get damaged. Note that the same is true when removing the board.
Alternatively, you can remove the latch from the retainer.
