Matrox Rapixo CXP base model. Matrox Rapixo CXP base model supports image capture from up to 4 high-resolution, high-speed video sources that use the CoaXPress (CXP) communication standard. There are two versions of the Matrox Rapixo CXP base model: Quad CXP-6 and Quad CXP-12.

Matrox Rapixo CXP Pro. Matrox Rapixo CXP Pro supports the same functionality as the base model, as well as FPGA-based processing offload capabilities (Processing FPGA). There is only one version of this model: Pro Quad CXP-12.
Matrox Rapixo CXP is a family of high-performance PCIe frame grabbers. There are two models:
Matrox Rapixo 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 Rapixo CXP can decode Bayer color-encoded images and perform color space conversions while transferring the images to the Host. In addition, it can vertically and horizontally flip them and perform subsampling.
Matrox Rapixo CXP can receive images from each video source at up to the maximum CXP-6 or CXP-12 speed (depending on the model of the board and camera). Using link aggregation, the bandwidth of a link can be increased to 4 times the maximum CXP-6 and CXP-12 speeds for a single video source. Matrox Rapixo CXP provides up to 13 W of power per CoaXPress connection to any device that supports power-over-CoaXPress (PoCXP).

Number of CoaXPress trigger signals (to camera only) |
1/digitizer |
|
Number of data latches |
1 Only for 8, 10, or 12-bit data (monochrome or color). When a link is receiving color data, all bands of the data use the same specified LUT mapping. In addition, as soon as one link is receiving 12-bit data, all links (CoaXPress connectors) share the same specified LUT mapping.
Note on nomenclature
This manual refers to all versions of the board as Matrox Rapixo CXP. When necessary, this manual distinguishes between the boards using their full names (for example, Matrox Rapixo CXP Quad CXP-6, Matrox Rapixo CXP Quad CXP-12, or Matrox Rapixo CXP Pro Quad CXP-12), or their abbreviated forms (Quad CXP-6, Quad CXP-12, and Pro Quad CXP-12).
