Design and Implementation of Display Platform Based on PowerPC7447 Processor

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.
