基于EMIF的高速图像传输系统设计

Design of High-speed Image Transmission System Based on EMIF

摘要:

CCD图像具有分辨率高,数据量大等特点,因此实时采集和传输图像成为难点。在传统采集与传输系统中,首先将采集的图像数据存储到存储介质中,然后再将数据从存储介质中读出进行分析,这种事后的分析不利于现场分析与调试。针对这个缺点,提出一种新的平台,可实时完成数据采集,并将采集的数据通过EMIF接口以约320 MB/s的速度进行传输与显示,这种新的平台具有可靠性高,可移植性强,升级简单,易于工程实现的优点。可作为高速采集与传输系统的参考设计。

Abstract:

CCD images have a property of high-resolution with huge amount of data.In traditional image gathering and transmission methods,the images are first collected and stored into storage medium,then read out for analysis,which is inefficient in real-time diagnosis and debugging.For eliminating the disadvantages,a new platform of CCD image gathering and transmission system is proposed,from which,the gathered data can be transmitted and displayed with EMIF interface at 320 MB/s.Test results indicate that this plat...
