Matrox Radient - Camera-Link Framegrabber with FPGA-based image-processing offload

The Matrox Radient eCL frame grabber matches the highest level of performance offered by the Camera-Link-interface standard with support for the maximum transmission rate beyond the maximum number of ports. The acquisition of such massive amounts of data is usually accompanied by image processing operations that can overwhelm the most capable computer. The Matrox Radient eCL also features an on-board real-time processing FPGA device that can be configured to offload and even accelerate the most compute intensive part of typical image processing applications without generating additional data traffic within the host computer.

Offload and accelerate repetitive tasks from the host CPU
As image size continues to grow, frame rate steadily increases and applications are expected to do more, the demands for processing on the host system are escalating. Alleviating this pressure, the Matrox Radient eCL can offload repetitive CPU intensive tasks on the Altera Stratix III FPGA such as spatial and temporal filtering, gain and offset correction, dead pixel correction, optical and perspective distortion correction, Bayer color interpolation, color space conversions and frequency domain transformations, freeing valuable processing resources for the rest of the application and accelerating the application. The operations performed on-board are controlled through the Matrox Imaging Library (MIL) application development software. Through MIL, a FPGA configuration can be rearranged to perform a required sequence of operations without having to necessarily generate a new FPGA configuration. When the need arises, Matrox’s FPGA design services can be employed to generate an applicationspecific FPGA configuration.

Versatile Camera-Link Interface
For field-proven, low-latency and deterministic acquisition, Camera-Link provides a scalable solution conceived specifically for machine vision applications. From costsensitive low data rate applications, to mainstream applications including color and right up to maximum bandwidth applications, Camera-Link is an excellent fit. The introduction of the mini Camera-Link connector (HDR) has lead to higher density multi-camera systems by enabling two Base or one Full mode Camera-Link-interface with triggering and general purpose I/O in a single slot.

The Matrox Radient eCL-QB is capable of simultaneously capturing from up to four completely independent Base Camera-Link-cameras at up to 85 MHz. Fully supporting Power over Camera-Link (PoCL), the Matrox Radient eCL-(Q)B can reduce cabling complexity and eliminate the need for bulky and costly external camera power supplies. Alternatively the Matrox Radient eCL-DF, supporting up to two Medium/Full cameras with up to 10-taps at up to 85 MHz, can acquire and reconstruct images from the most advanced multi-tap highperformance area and line scan cameras.

High-performance host interface
A x8 PCIe host interface provides the throughput necessary to ensure the continuous flow of pixels from the Matrox Radient eCL to host memory. With a peak bandwidth of up to 2 GB/s, the Matrox Radient eCL’s host interface prevents pixels from inadvertently being discarded while the point-to-point connectivity of PCIe stops other add-in devices from taking away valuable bandwidth between the frame grabber and the host PC.

Lifecycle managed for consistent long term supply
Matrox Imaging not only carefully selected each component in the Matrox Radient eCL to ensure product availability in excess of five years, but also exercises strict change control to provide consistent supply. Longevity of stable supply lets OEMs achieve maximum return on the original investment without incurring the additional costs associated with the repeated validation due to constantly-changing products.

Application development with Matrox Imaging Library (MIL)
Complementing the Matrox Radient eCL is the Matrox Imaging Library (MIL) providing a comprehensive collection of software tools for developing industrial imaging applications. MIL features interactive software and programming functions for image capture, processing, analysis, annotation, display and archiving. These tools are designed to enhance productivity, thereby reducing the time and effort required to bring your solution to market. The MIL API is not only intuitive and straightforward to use but it is also portable. It allows applications to be easily moved from one supported video interface or operating system to another, which provides platform flexibility and protects the original development investment.
