General Acquisition Features; Acquisition Memory; Additional Functionality - Matrox Radient eV-CXP Installation And Hardware Reference

Matrox Radient eV-CXP features four independent CoaXPress links (acquisition
paths). This makes it possible to perform simultaneous image capture from up to
four video sources that transmit data at different CoaXPress speeds (up to
6.25 Gbits/sec). Alternatively, using link aggregation, the frame grabber can
receive image data at up to 25 Gbits/sec from a single video source. Matrox
Radient eV-CXP provides up to 13 W of power per CoaXPress link to any device
that supports power-over-CoaXPress (PoCXP).

General acquisition features

Matrox Radient eV-CXP supports frame and line-scan monochrome and color
video sources. The color video sources can be RGB video sources or video sources
with a Bayer color filter. Matrox Radient eV-CXP can decode Bayer color-encoded
images and perform color space conversions on-board.

Acquisition memory

Matrox Radient eV-CXP is equipped with 1, 2, or 4 Gbytes of DDR3 SDRAM
acquisition memory, which is used to store acquired images. This memory is
accessed through the memory interface. The memory interface has multiple input
ports and a data transfer rate of up to 8.5 Gbytes/sec.

Additional functionality

In addition to the core video capture capabilities, Matrox Radient eV-CXP
incorporates a variety of features to simplify overall system integration. These
features include:
• Color space converter and image formatter. This can convert data as it is being
transferred to the Host. It 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, it can flip 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 can be configured as user-defined signals,
or to some other functionality depending on the auxiliary signal (for example, as
trigger input or exposure output signals). Matrox Radient eV-CXP features 32
auxiliary signals that are independent of the acquisition path, accessible via four
DBHD-15 connectors. Each DBHD-15 connector has 3 TTL configurable
auxiliary inputs/outputs, 2 LVDS auxiliary inputs, 1 LVDS auxiliary output, and
2 opto-isolated auxiliary inputs.
