基于Zynq-7000的视频处理系统框架设计
Design of Video Processing System Framework with Zynq-7000
摘要
Abstract
With the continuous development of embedded machine vision technology,the requirement of video data bandwidth,processing speed and data accuracy has become higher and higher.Current embedded image processing system are mainly based on ARM with DSP framework.Such designs normally come with deficiencies as low acquisition speed and limited processing bandwidth.To address this problem,Zynq-7000 has been adopted to realize a video processing framework by synergy of FPGA as hardware and ARM as software.FPGA acts as an implementation of parallelized image preprocessing algorithm as well as ARM processing unit to control the program flow and to implement the complex image processing algorithms are integrated in this framework.A DDR buffer has been exploited to coordinate the hardware and software.Such synergy ensures the processing efficiency and bandwidth of system,while considering the flexibility of system simultaneously.The experimental results show that not only can the design provide a high speed color image acquisition and preprocessing,but also can implement a high performance image processing algorithm with video display of graphic results.关键词
