Hardware Design And Implementation Of Airborne Video And Graphics Display System Based On FPGA

The airborne video graphics display technology is a key technology in avionic electronic technology, whose core content mainly includes processing and real-time generation of video graphics, low power design. This dissertation is dedicated to the design and implementation of hardware platform, The debugging work is accomplished.The main researches of this dissertation are summarized as follows:1) In accordance with low-power and modular design thought, the hardware platform is mainly divided into video input module, video output module, memory module and peripheral auxiliary module. The architectural design of the hardware platform, which is based on Kintex 7 FPGA, is presented in this dissertation.2) Based on the module partition, the detailed circuit designs of each module are presented in this dissertation. Among them, video input module completes digital signal acquisition of PAL analog video and high-speed DVI video. Video output module realizes two rails of 1.62 Gbps high-speed DVI video output. The high-speed cache module is based on dual DDR3 memory used for video and graphic sepearately, which simplifies the algorithm design. The design of periphery auxiliary module is presented in this dissertation, which mainly includes the optimization design of power distribution network, the design of clock distribution network and the design of PCI/PCI-E high-speed communication interface.3) The simulation analysis after wiring of DDR3 high-speed memory interface is accomplished through Hyperlynx. The simulation result shows that, the signal quality high-speed DDR3 menmory interface is good at the 1600 Mbps read and write rate.4) The comprehensive test on hardware platform is accomplished. The results of experiments show that, all the index requirements including power quality, clock stability, display quality, system power consumption and heat dissipation are met. With the software and hardware joint debugging, system supports real-time processing and output high resolution video. The system power consumption is only 12 W at the normal status, which is about 1/3 of data from literature...
