摘　　要：PCIe总线不仅硬件接口简单,软件和PCI总线完全兼容,而且传输速度数十倍于PCI总线。针对载机任务系统实时视频采集记录的需求,设计了一种基于PCIe总线的航空视频采集记录系统,利用现场可编程逻辑器件(FPGA)实现了视频数据流的编解码和PCIe桥接口的设计,简化了硬件接口设计,提高了系统的工作效率。系统在某型数字化对抗训练系统中的实际应用表明该设计实用可行。The PCIe bus has not only simple hardware interface, but also has full compatibility between software and PCI bus, and decades of higher speed than that of PCI bus. Aiming at the demand of real-time video data acquisition and record for airborne mission system, an aerial video acquisition and record system based on PCIe bus is designed. The system realizes video data streamline code-decode and PCIe bridge interface through FPGA, which simplifies the design of hardware interface and improves the work efficiency of the system. Its successful implementation and application in one digital counterwork training system proves that the design is feasible and practical.
