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,态势和飞行参数等技术提供了支持。通过综合测试和应用表明,该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 avionics system on display technology demand, according to the application characteristics of airborne environment, put forward the display design platform based on PowerPC7447 processor, and the constitution and function of the platform were designed,display platform through the centralized control and comprehensive display, timely response andconcentration of various orders, processing pilot at the same time, display graphics processing and data processing ability strong platform in three-dimensional map is displayed based on the superposition of navigation, situation and flight parameters and other technical support. Through the test and application shows that, the display platform has strong universality, expansibility, high throughput and dynamic characteristics of graphics processing higher efficiency, for the promotion of cockpit display significant effect.
