摘要 针对当前信息处理教学平台存在相互独立、兼容性和开放性差等问题,设计了一种基于嵌入式Linux信息处理的开放性教学平台。该教学平台以imx6为核心处理器,设计有多个信息处理硬件接口,可同时接入多路图像、语音和其它信号。其借鉴Linux系统架构思想,应用层软件采用分层架构,便于功能裁剪和扩展,且平台代码完全开源,便于师生编写和添加信息处理代码。此外,该平台设计了基于视频信息的传输、解码和播放的教学案例,将其应用于电子信息工程专业课程设计教学过程中,教学效果表明其具有较好的开放性和兼容性。 Aiming at such problems as mutual independence,poor compatibility and openness existing in the current information processing teaching platforms,an open teaching platform based on embedded Linux has been designed.This teaching platform takes imx6 as the core processor,and has multiple information processing hardware interfaces,which can access multiple images,voice and other signals at the same time.Referring to the Linux system architecture,the application layer adopts a hierarchical architecture,which is convenient for function cutting and expansion.The platform code is completely open source,which is convenient for teachers and students to write and add information processing code.Furthermore,a teaching case of video information transmission,decoding and playing has been designed on the platform,and the case has been applied to the course design teaching of electronic information engineering.The teaching effect shows that the platform has good openness and compatibility.
