基于Zynq的机载液晶显示器显控系统设计

Design of Display and Control System of Airborne LCD Monitor Based on Zynq

设计了一套基于Zynq平台的机载液晶显示器显控系统,集成了背光调节、按键处理、温度采集、低温加热、串口通讯、仪表界面绘制、显示驱动等功能,采用软硬件协同设计的方法,对各项功能进行软硬件的设计划分,充分利用了Zynq平台中可编程逻辑部分强大的并行数据处理能力和处理器部分灵活高效的嵌入式编程模式。经试验验证,该系统运行良好,各项功能满足设计要求,具有一定的工程应用价值。

A display and control system of airborne LCD monitor based on Zynq platform was designed.This system synthesized various functions,such as backlight,key handling,temperature acquisition,low temperature heating,serial communication,instrumental interface display,display driver,etc.It adopted the hardware and software co-design to partition these functions,and took full advantages of the ability of parallel data processing of FPGA in Zynq platform and the flexible and efficient embedded programming model of ARM.Finally,the experiment results demonstrated that the designed system could operate well and all the functions could satisfy the predesigned requirements,which implied the potential engineering value.
