DE1-SoC开发平台上的图像采集系统设计

Image Acquisition System Based on DE1-SoC Platform

本文详细介绍了基于Altera片上系统FPGA的嵌入式系统的设计方法,包括基于Qsys的系统硬件设计和基于片上系统EDS嵌入式软件设计。该设计采用Altera公司提供的soc_training image镜像内核文件,写入外存SD卡中,进行启动Linux操作系统,在QSYS中构建所需的硬件模块,在EDS开发套件平台上编写应用软件程序,最后通过板级验证实现系统功能。该系统通过FPGA的Video-in接口,实现了图像的捕捉功能,并存入到外设SD卡。

In the paper,the embedded system design method based on Altera＇s SoC FPGA is introduced,including the system hardware design based on Qsys and embedded software design based on SoC EDS development suite. The soc training image kernel image file is used to write to the external SD card, then the Linux operating system is started. The required hardware module is, added in Qsys and the application software is added in EDS development kit platform. Finally, the system function is realized through the board level verifica- tion. The system realizes the function of image capture by FPGA Video-in interface, and deposited it in the SD card.
