All high-resolution video frame rate (HD) Security Control processing system processing devices have become increasingly demanding, single-chip DSP processing can no longer fit, multi-chip, multi-core or CPU + DSP approach although in some cases to meet the demand, but its cost in the PCB, the system resource consumption and system stability problems still exist. FPGA load characteristics using a flexible video processing engine, the new system architecture is cause for concern.

Cost and performance challenges Xilinx Asia, said a senior systems architect Jiang Yungui, intelligent surveillance video analysis system Market Size in 2012 will reach 800 million U.S. dollars. For video surveillance cameras and DVR and other network equipment designers and providers, subject to the processing performance, cost and Power supply And other constraints, commercial or single-chip solution is technically feasible. The use of their Spartan-3ADSPFPGA programmable and cost advantages to meet the camera, the virtual obstacle, object statistics, the number of lag and various monitoring functions, and form a single chip integrated into the camera.

FPGA to achieve this requires a powerful video processing engine to support the Eutecus Berkeley, California Company Developed a cellular visual technology (CVT), which is the next generation of very high-speed image flow capture and processing technologies, integrating a large number of independent parallel processing architecture and algorithms. Eutecus said President and Chief CEOStephenD.Hester, CVT technology by the human eye's processing architecture inspired by the technology they can use for intelligent video surveillance and security market for FPGA and other devices to provide image processing IP. "We are in the development of multicore video analytics engine (MVE) encountered a problem," Hester said, "Our first generation Product Based on TI's DaVinci SoC. But in the second generation, we need more processing power and system integration. Multiple DSP devices or programs in terms of cost effectiveness at the system level is not high. We need an easily transplanted to the previous generation, and we can provide more features second-generation MVE single-chip solution. "

Spartan-3A-based processing architecture After some research, Eutecus found Xilinx's Spartan-3ADSP3400A. The device in the 126 XtremeDSPDSP48A logic chip can provide up to 30GMAC of DSP performance, so full video analysis applications to meet the demanding cost and performance requirements. MVE can be achieved under the processing in the video frame rate HD resolution, and power less than 1W. It is easy to configure, compact processing architecture can be configured in an integrated building blocks inherent in multi-core parallel processing architecture, embedded complex video analysis algorithms, thus simplifying the hardware design and programming. MVE full implementation of multiple simultaneous events Detect And the parallel classification algorithm.

Move from one platform to another platform architecture, portability is an important factor to consider. Xilinx's EDK Embedded Development Kit allows the embedded processor based on XilinxMicroBlaze dual-processor hardware architecture and the TI DaVinci platform companies like dual-processor architecture. Thus, Eutecus transplantation in the design without any concerns.

"MVE is embedded in the Xilinx Spartan-3ADSPFPGA in, can make intelligent camera or other network devices such as the DVR in a single chip to achieve complex video analysis capabilities." Jiang Yungui said, "Using FPGA to add more according to customer demand Video analysis of functions and events related to test cases. can use the same hardware platform to create a wide variety of derivative products. Eutecus VHDL design using a variety of accelerator engine, and these special cores integrated into C-MVA coprocessor. This methods allow engineers to re-use of dual MicroBlaze embedded system to create a different FPGA programming file, thus constitute a highly scalable solution that can be easily adjusted to adapt to a wide range of video analysis applications.
