Family of singal processing cores for video enhancement

November 19, 2012 // By Nick Flaherty
UK signal processing experts RFEL is extending its military designs into the industrial market with a new family of Video Processing IP cores.

High quality video processing have always been in demand for military and security surveillance and targeting systems. Such systems require high resolutions, high frame-rates, ultra-low latency and mission-flexibility through provision of live re-programmability. For example, video must be enhanced, rotated or similarly corrected in real-time; In software based solutions, this can often take a lot of power and, crucially, time. Conversely, a wholly custom hardware solution lacks adaptability and intelligence. RFEL has proven that FPGAs are a perfect platform to create solutions that meet the user's demanding requirements with RFEL's flexible and deterministic FPGA IP core building blocks. The IP FPGA cores can be supplied with standard software interface frameworks to simplify their deployment and RFEL can modify the cores if required to meet the requirements of constrained resources or legacy platforms.

"For the past 12 years, we have built our expertise in Digital Signal Processing and created award-winning solutions for RF on FPGAs," said Dr Alex Kuhrt, RFEL's CEO. "We have found that there is a lot of common ground with processing video and so we have been able to leverage our libraries of proven IP cores to rapidly create a new family of Video Processing cores. These are available now, either as standalone cores or as part of a system solution created by our Design Services team to meet a customer's requirements, which we find are increasingly for a complete product."

A Digital Rotation core supersedes mechanical rotation hardware with state of the art digital processing. Many of the digital rotation IP core features can be configured while the system is still running, so that the user is always fully in control. Reliable, maintenance-free and targeted to low-cost FPGA devices, the digital rotation IP core is a highly efficient, arbitrary sub-degree angle, real-time, 360 degree rotation engine.

The Digital Re-sizing and Digital Zoom (DZ) core far exceeds the efficiency and reliability of software-based, image magnification solutions, manipulating images
