Qsys平台的SoC图像传输控制器设计

介绍了用Altera公司的CylconeV系列SoC芯片来实现图像传输控制的方法.512×640像素点的图像数据存储于该芯片PL侧的ROM中,通过FIFO缓存和AXI总线实现PL部分和PS部分的图像数据的交互.整个SoC系统的搭建基于Qsys平台,HPS侧在Linux嵌入式系统基础上开发应用程序,以读取文件数据的形式将像素点的数据通过以太网发送给上位机.上位机通过Matlab软件实现原始图像的恢复.

Design of SoC Image Transmission Controller Based on Qsys Platform

In the paper,the method of using Altera's CylconeV series SoC chip to realize image transmission control is introduced.The image data of 512 × 640 pixels is stored in ROM on the SoC chip's PL side,and the interaction between the PL part and the PS part is realized through FIFO cache and AXI bus.The whole SoC system is built on the Qsys platform.The HPS side develops applications based on Linux embedded system.The HPS sends the pixel data to the upper machine in the form of reading file data.The restoration of the original image of the upper plane is realized by Matlab software.
