Design And Implementation Of Embedded Linux Video Collection System

With the development of video signal processor,embedded video monitoring system was used more and more widely,and the demand for intelligent video surveillance has become increasingly high.After studying the latest Davinci technology of Texas Instrument(TI),this thesis,aiming at the family environment,designs an intelligent video monitoring system.The thesis related to Davinci technology hardware architecture,software architecture and linux application design.This thesis uses davinci technology dual-core processor TMS320DM6446 as the main processor;the hardware system design involves video input and output interface design,DDR2 dynamic memory interface design,Flash Memory Interface Design,ATA hard disk interface, serial memory interface design,audio interface design,Ethernet interface,USB interface,UART interface,the external control interface design and power supply system design.In this paper,the various components of the hardware system's functions and features are also introduced in detail. The algorithm parts of Davinci software framework are highly modularized;greatly enhances the independence of the algorithm and application procedures.The software is developed under Davinci software framework which can be applied to kinds of embedded operating systems.In the end,the task of this paper is summarized.Meanwhile the paper also brings forth the improvement and perfect work in the next step.And all the research work has established a foundation for the further research and development of Embedded Linux Video Collection System,and it has practical reference value.
