机载图像处理引擎实时仿真平台

Real-time Simulation Platform for Airborne Image Processing Engine

针对航空电子系统中图像处理模块数字化设计的趋势,建立了一个完整的机载图像处理实时仿真平台。该平台以电子系统级设计(ESL)方法为基础,利用Handel-C语言将视频处理系统中关键算法模块抽象为知识产权核(intellectual property core),同时进行系统级仿真与验证,并通过FPGA实现。解决了单纯用软件实现算法实时性差、难以协同设计验证的问题。座舱综合显示和视景增强子系统被用来作为案例在该平台上实现,验证了平台仿真的实时性。

Coped with the trend of digital design of the image processing module in avionics system,a complete real-time simulation platform for airborne image processing was established.Based on ESL design methodology,the platform abstracted key algorithm module in video processing system as IP core using Handel-C language,made simulation and validation at system level,and realized via FPGA.The difficulty of poor real-time capability,co-design and verification was addressed,which could not be handled only by software algorithm implementation.As case study,integrated cockpit display and enhanced vision subsystems were implemented on the platform to verify real-time feature.
