摘　　要：根据航空电子系统对显示技术的需求,针对机载环境的应用特点,提出了基于PowerPC7447处理器的显示平台的设计方案,并对该平台的构成及功能实现进行了设计。显示平台通过集中控制和综合显示,能及时响应和集中处理飞行员的各种命令。同时,显示平台强大的图形处理和数据处理能力对在三维地图显示基础上叠加导航、战术和飞行参数等技术提供了支持。通过综合测试和应用表明,本显示平台具有通用性强、可扩展性强、数据吞吐量大和动态图形处理效率高等特点,对于提升座舱显示效果具有重要意义。According to the requirements of the aviation electronics system on display technology, and aiming at the application characteristics of airborne environment, this paper proposes a design scheme of the display platform based on PowerPC7447 processor, and designs the constitution and function implementation of the platform. The display platform can timely response and centrally process various orders from pilot through the centralized control and integrated display. Moreover, the powerful graphics processing and data processing ability of the display platform provides a technical support to the technology of stacking navigation, tactics and flight parameters on the basis of 3D map. Comprehensive testing and applications shows that the display platform has strong universality, strong expansibility, high throughput and higher efficiency of dynamic graphics processing, which has important significance to the improvement of cockpit display.
