座舱显示系统内核渲染器研究与实现

随着近几年综合航电系统的迅速发展,作为航电系统中重要组成部分的座舱显示系统也向着开放式构架发展,为适应这种发展趋势,ARINC661协议应运而生。协议将用户应用(UA)的逻辑功能与座舱显示系统(CDS)的画面生成功能相隔离,并为两者提供了标准化的接口。基于ARINC661协议的CDS可解释定义文件(DF)及动态运行指令,通过调用内核渲染器,完成对画面的实时渲染。要实现CDS中画面的成功显示,渲染器的设计非常重要。通过对ARINC661协议的分析,重点研究了窗体部件的渲染技术,设计了基于ARINC661协议的内核渲染器,为国内航电显示设备的研究提供了帮助。

Research and Implementation of Kernel Renderer of Cockpit Display System

In recent years the integrated avionics system is developing rapidly.Cockpit display system is an important part of aviation system to open architecture development,and ARINC661 regulate is appeared in this development tendency.This regulate separates the logical functionality of UA and the display functionality of CDS,and provides a standardized set of interfaces.The CDS,based on ARINC661 regulate,can explain DF and dynamic operation instructions.Then it does real-time rendering by calling the kernel renderer.For displaying the picture successfully,the design of the renderer is very important.The technique of kernel Renderer is studied by analyzing the principle of ARINC 661 Specification.On this basis,a kernel Renderer is designed,and it is useful for the research of avionic display devices in our country.
