摘要
为了实现对高清视频图像的实时处理,提出了一种以HDMI高清图像为目标基于FPGA实现高清视频流的图像处理系统的设计。系统设计过程包括配置processing_system处理器、视频输入HDMI接口输出VGA接口的IP核设计、图像处理IP核的设计和应用程序设计4部分。以processing_system处理器为处理核心,通过片内添加外设接口和设计HDMI接口输入和VGA接口输出的IP核在ZYBO开发板上搭建嵌入式硬件平台,在硬件平台中设计图像处理的硬件IP核。实验结果显示,在系统工作频率为650 MHz时,能以58帧/s的处理速度处理图像,并通过VGA接口将处理后的图像输出到显示器。
In order to realize the real-time processing of HD video,this paper presents a design of image processing system for high-definition video stream based on FPGA. The system targets HDMI HD images. System design consists of4 parts： configuration of processing system processor,IP core design of HDMI interface for video input and VGA interface for output,IP core design of image processing,and application design. By taking the processing system processor as processing core,the embedded hardware platform in the ZYBO development board is constructed by adding on-chip peripherals interface and designing an IP core of HDMI interface for input and VGA interface for output. Based on the platform,the hardware IP core is designed to realize the real-time processing of HD video finally. The experimental results show that,the system can process the image with a processing speed of 58 frames per second,and output the image to display through VGA interface when the working frequency is 650 MHz.
