基于i.MX21的视频电话设计与实现
摘要
本课题提供了一种视频电话的设计方案,可满足企业用户和个人用户对视频通话的需求。通过方案制定,芯片选型,原理图设计,PCB设计,操作系统移植等环节,设计并实现视频通话的基本功能。研发意义在于提供了单芯片实现网络视频电话的设计方案,以及可由此扩展的各类视频产品,如电子相框,实时监控设备,手持终端设备和其他消费类电子产品的设计和研发。
本文通过对市场上常见的各种多媒体控制芯片的综合比较,完成了以飞思卡尔半导体出品的i.MX21作为核心芯片的IP视频电话设计方案,包括完整的硬件系统设计。
论文大致分为三大部分七个章节,第一部分是第一二两章,为概述部分,介绍了本课题完成的主要工作,课题研究的背景,涉及的相关技术等。第二部分为本课题的详细设计部分,包括三四五章,从视频电话的设计方案选取介绍起,到硬件芯片的参数功能介绍,以及详细硬件设计,包括各个模块和接口的设计。最后一部分介绍了PCB设计和课题进行中遇到的难点及解决情况。
This topic gave a videophone design project which can feed the needs of both enterprise and personal use.The videophone was completed by project design, component choose, schematics and PCB design, OS transplant.This project gave a single-chip development solution, not only for videophone, also for other digital products like digital photo album, real-time supervisor, PMP and others.
Comparison of all the multimidea controllers in the market, the project used i.MX21 from freescale semiconductor as the core chip of the design.The porject includes the whole hardware design and the transplant of embeded operating system—Linux
This essay divided into three sections included seven chapters. The first part included two chapters, mainly introduct the major work on the subject, the background research and related technologies.The second part included the design selection, chip function introduction and the detailed hardware design of the videophone. The last section is a introduction of the disign of PCB and the problem met in this project.
