Research And Implementation Of Advertising Media Player Based On AMD's Embed Processor

The Advertising Media Player is a kind of equipment used for Advertising. It displays the objects to audience with video and audio frequency.This paper makes researches about an Advertising Media Player design project and the implementation of the project. Firstly, the meaning of Advertising Media Player product is put forward, and then the main processor is chosen by projects compare. Secondly, as background knowledge, video compression and video compression coding technology are introduced, especially the MPEG-1/2 and MPEG-4 video compression standard. Thirdly, the characteristics about video, audio frequency, memory, clock, power and interface of the processor are described detailedly. Following that, macroscopical design projects for both hardware and software are given. Fourthly, combining the DDR2 SDRAM, Low Voltage Differential Signal and power management technology, the paper concretely deals with the design of periphery unit circuit including the memory unit, audio CODEC unit, LCD displayer unit, Ethernet unit, interface unit, clock unit and power unit. Finally, makes sum-up of the paper and indexes the way to improve the project.
