摘要:
飞机飞行过程中的视频记录对飞行训练评估、战时调查分析以及新型飞机的研制和试飞具有十分重要的意义。目前市场上的多路视频记录仪多采用DSP或核心编码电路加外围电路的方式实现,系统复杂度较高,灵活性差。文中针对现有实现方式的不足及多路音视频记录仪的系统需求,提出了一种基于SoPC的多路音视频记录仪的系统架构,重点阐述了该记录仪的系统组成、外围接口电路、SoPC逻辑及SoPC软件的设计与实现。测试结果表明,该多路音视频记录仪功能、性能完全满足系统应用需求。
Abstract:
The flying Audio and Video ( AV) information recorded in real time is very important in evaluating flight quality and researc-hing in wartime,which is available for the development of a new type of avion at the same time. Currently on the market multi-channel digital AV recorder uses DSP or CODEC circuit and peripheral circuit to implement,system complexity is higher,and the flexibility is poor. In view of the shortage of the existing implementation way and the system requirements,propose a system architecture of multi-channel digital AV recorder based on SoPC. Then expound the composition of the AV recorder system,the peripheral interface circuit,the design and implementation of SoPC logic and SoPC software. The test shows that the function and performance of multi-channel digital AV recorder completely meets the system requirements.
