摘　　要：为了满足小型通用飞机对飞行显示器性能、功耗、体积、成本等多方面的要求,实现了一种基于双处理器的飞行显示器数据处理单元。首先介绍了小型通用飞机对飞行显示器的设计需求,其次详细描述了飞行显示器的系统结构和数据处理单元的软硬件实现,最后通过典型主飞行显示界面的实现,验证了数据处理单元的功能。验证结果表明,该数据处理单元具有处理能力强、集成度高、功耗低和扩展性强的特点,具有广泛的应用前景。In order to fulfill the requirements of flight display＇s performance, power dissipation, volume, cost etc in the small general aircraft, a data processing unit of flight display based on double processors is realized. First, the paper introduces the de- sign requirements of flight display in the small general aircraft. Then it describes the system architecture of flight display and the realization of software and hardware in data processing unit in detail. At last, the function of data processing unit is validated through the realization of typical primary flight display interface. The experiment indicates that the data processing unit has the characteristics of high data processing capability, high integration, low power dissipation and high extending capability, which has broad application prospects.
