毕业设计 基于Android的嵌入式音频系统 摘要 Android一词的本义指“机器人”，同时也是Google于2007年11月5日宣布的基于Linux平台的开源手机操作系统的名称，该平台由操作系统、中间件、用户界面和应用软件组成，号称是首个为移动终端打造的真正开放和完整的移动软件。系统硬件平台采用飞凌OK6410开发板，软件平台采用操作系统。论文对嵌入式系统进行了较详细的介绍，阐述了OK6410开发板的结构和特性，分析了操作系统的原理，研究了的应用开发过程，描述了开发环境建立方法，并设计实现了音频采集、存储、处理、播放和传输的功能。 关键词：、嵌入式系统、音频系统、飞凌OK6410 Abstract The word Android meaning refers to the robot, Also Google announced on November 5, 2007 that the Linux platform based on open source mobile phone operating system name, the platform by the operating system, middleware, user interface and application software, which is the first for the mobile terminal to create a truly open and complete mobile software. The subject of a design based on the Android embedded audio system. The system is mainly to achieve the audio collection, storage, and broadcast transmission. Acquisition by the SD card with voice or Android built-in microphone sound collection; processing is in the audio during acquisition of audio collected voice coding rules; storage is on acquisition and processing complete audio preservation; play is to realize the audio play, pause, continue, the replay, stop function; transmission is the audio playing position is passed to the player for playing; transmission refers to the development board audio file transfer between PC and. The system hardware platform by filling the OK6410 development board, software platform based on the Android operating system. Research on embedded system in detail, describes the OK6410development board structure and characteristics, analysis of the Android operating system principle, studies the audio system development process, described in the Android development environment to establish methods, design and realize the audio collection, storage, processing, and broadcast transmission function. 分享到 翻译结果重试 抱歉，系统响应超时，请稍后再试 支持中英、中日在线互译 支持网页翻译，在输入框输入网页地址即可 提供一键清空、复制功能、支持双语对照查看，使您体验更加流畅 Key Words:android、Embedded system、Audio system、ForlinxOK6410 1.绪论 3 1.1当前市场需求分析 3 1.2 android操作系统简介 3
