摘要
利用高性能嵌入式MXT0106微处理器设计了移动多媒体系统。该系统采用Uclinux操作系统进行音频解码,CS4334立体声D/A数字音频转换,LM4755功率放大,TFT-LCD触摸屏彩色显示;利用M65831和LM324的结合,实现了较好的音视频效果。该系统具有文本阅读、图片浏览、MP3播放、MP4播放、移动存储等功能,亦可作为卡拉ok系统使用。
A mobile multimedia system using MXT0106 embedded microprocessor was designed in this paper.In the system,we use uclinux operating system software for Audio Decoding.Besides,CS4334 stereo D/A converter for Digital Audio,LM4755 power amplifier,TFT-LCD,M65831 and LM324 are also used to achieve an excellent audio and video effect.This system can be used as text reading,photo browsing,MP3 player,MP4 player or mobile storage.It can also be ok as a karaoke system.
