Matrox Rapixo CXP board 11
Before the Processing FPGA can process grabbed images, they must be stored in
on-board memory. If images stored in Host memory are required, they can be
streamed directly to the Processing FPGA for processing. Images and other data
resulting from processing can be stored in on-board memory or streamed to the
Host.
Additional functionality
In addition to the core video capture capabilities, Matrox Rapixo 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 using an average
demosaicing algorithm. The following Bayer patterns are supported: GRBG,
GBRG, BGGR, and RGGB.
• Auxiliary, multi-purpose signals (32 with the cable adapter bracket installed).
These are non-video signals that can support one or more functionalities (for
example, trigger input, rotary/linear encoder input, or timer output), depending
on the auxiliary signal.
• Integrated quadrature decoders. These can decode input received from a rotary
or linear encoder with quadrature output.
• Programmable lookup tables (LUTs). These allow Matrox Rapixo CXP to map
data to precalculated values, before it is stored in memory.
• Matrox Rapixo CXP can provide up to 13 W of power per CoaXPress connection
to any device that supports power-over-CoaXPress (PoCXP), at a nominal voltage
of 24 V. The internal auxiliary 12 V power connector must be connected to the
computer’s power supply cable that has a 6-pin, compatible, mating 12 V
connector.
