Matrox Imaging has introduced a CoaXPress (CXP) frame grabber developed from the Matrox Radient family. According to the company, the Matrox Radient eV-CXP is a dependable high-performance image capture solution that combines a field proven design with the new CXP interface.

The Matrox Radient eV-CXP provides four independent CXP links through the required BNC connectors. This allows for simultaneous capture from up to four cameras each running at different CXP speeds. For high-bandwidth applications, the frame grabber can also capture from a single camera transmitting image data at up to 25Gbit/s using link aggregation.

To handle high data rates, the Matrox Radient eV-CXP has a PCIe 2.0 x8 host interfacewith a peak transfer rate of up to 4GB/scombined with up to 4GB SDRAM of on-board buffering. This ensures reliable capture to host memory. In cases with extremely high video frame rates (i.e., thousands of frames per second), users have the option of relying on the Matrox Radient eV-CXP's on-board MicroBlaze soft processor to offload image acquisition management from the host CPU. The frame grabber can also offload the host CPU from having to perform image pre-processing (i.e. Bayer interpolation, color space conversion and LUT mapping) tasks.

Beyond host offloading, the Matrox Radient eV-CXP simplifies overall system integration by providing camera power, trigger and control over each CXP link, as well as four independent sets of auxiliary I/O for interfacing with rotary encoders, photoelectric sensors and strobe controllers, noted Matrox. By having the primary set of auxiliary I/Os on the same bracket as the BNC connections, the Matrox Radient eV-CXP offers a true single PCIe slot solution for single camera applications, added the company.

The Matrox Radient eV-CXP is fully supported by the Matrox Imaging Library (MIL) toolkit on 32bit and 64bit Windows 7 and Linux. The solution will be available in 1Q12.
