Research On Image Acquisition And Processing System Based On YHFT-QDSP+FPGA Architecture

With the wide application of image processing technology, high performance real-time image acquisition and processing systems has been paid more and more attention. The real-time image acquisition and processing hardware platform generally consists of four parts, respectively is the real-time image acquisition, processing, storage and display. The performance of hardware platform determines the image algorithm can be brought into full play. The hardware platform for a variety of image processing systems implementation architecture, including DSP + FPGA architecture image acquisition and processing platforms easily between system performance and development cycle to get the balance point, is currently the most practical way to achieve based. Taking into account the effect of DSP on image processing algorithms, DSP chip Defense Systems School of Computer Science and Technology, University independently developed high-performance heterogeneous multicore YHFT-QDSP.Design of the whole system is based on YHFT-QDSP + FPGA architecture, with ADI’s video codec chip, the hardware platform to build real-time image acquisition and processing system. To select core chip(DSP and FPGA) design through functional systems needed, throughout the design process adhere to universal, portable, scalable principles. The main work in the following areas:1. DSP and FPGA chip analysis alone in the use of real-time image acquisition and processing system of the advantages and disadvantages, according to the technical route of this paper is designed based on YHFT-QDSP + FPGA architecture for image acquisition and processing system.2. Design of the system hardware circuit. On top of YHFT-QDSP, FPGA, image acquisition interface, image display important data interface module cir cuit between interfaces, image storage interfaces, YHFT-QDSP and FPGA to do a thorough research and analysis, to complete the circuit design of each module.3. On the basis of the framework on the system hardware, system software framework design; and software modules within the framework design, including communication between the image acquisition module, image storage module, an image display module, YHFT-QDSP and FPGA module.4. Upon completion of the system after the hardware and software design, build test platform to test the system as a whole, and to analyze the utilization and overall performance of the system resources.After testing to verify that the system can correct and reliable complete real-time image acquisition, image storage function, image display, image data is transferred to YHFT-QDSP accessible storage space for YHFT-QDSP algorithms for image processing. Testing showed that the system enables real-time image acquisition, storage,display and image processing functions for the next reservation.
