Single- to quad-input CoaXPress 2.0 frame grabbers with optional data forwarding and FPGA-based image processing offload

Matrox® Rapixo CXP is a new generation of frame grabbers, supporting version 2.0 of the CoaXPress® digital interface standard for machine vision applications. The Matrox Rapixo CXP series supports data rates of either up to 6.25 Gbps (CXP-6) or up to 12.5 Gbps (CXP-12) per connection. The PCIe® host interface comfortably matches the maximum input bandwidth from the CoaXPress links. The CoaXPress links are accessed through high-density BNC connectors allowing for a homogenous interconnection with new cameras. Power-over-CoaXPress (PoCXP) support on each connection simplifies system configurations, combining the camera’s power interface with its command- and data-interface onto the same coaxial cable.

The Matrox Rapixo CXP series of frame grabbers feature one, two, or four connections for interfacing to independent cameras. Matrox Rapixo CXP Dual and Quad models can also handle higher data rates through connection aggregation. The Matrox Rapixo CXP series possesses sufficient onboard memory to buffer incoming image data in situations where the host computer is temporarily unable to accept data. The fanless design for select models ensures extended use without maintenance.

    FPGA-based image processing offload

    FPGA-based image processing offload
    The Matrox Rapixo CXP Pro makes use of an FPGA device from the Xilinx Kintex® UltraScale™ family for not only integrating the controlling, formatting, and streaming logic of the various interfaces, but also allowing developers to incorporate Matrox Imaging- or user-developed custom image pre-processing operations to offload from the host computer. A variety of FPGA sizes are available for the Matrox Rapixo CXP Pro, providing a range of solutions tailored to a given application. Operations performed on-board are controlled through MIL X application-development software. Within MIL X, an existing FPGA configuration can be rearranged to perform a required sequence of operations without necessarily having to generate a new FPGA configuration. Using the Matrox FDK, developers generate their own FPGA configurations with custom operations written in C/C++.

    Data forwarding for distributed processing

    Data forwarding for distributed processing
    The Matrox Rapixo CXP series also offers the possibility of distributing image processing across multiple computers using the data forwarding option. This feature enables the relaying of images to another computer using four output connections running at 12.5 Gbps. The data forwarding is accomplished without host computer involvement as image data is re-transmitted prior to also being stored in onboard memory thus minimizing latency. Images can be retransmitted to multiple computers in a daisy chain fashion by equipping each PC with Matrox Rapixo CXP with data forwarding option.
