基于ARM920T的入式音频接口系统设计.docVIP

【摘要】 自从电子技术发展起来之后,ARM因其体积小、低功耗、低成本、高性能的优势,正以惊人的速度向前发展，在工业控制、消费类电子产品和成像安全产品、无线网络与通讯等领域得到了广泛应用，极大地改进了这些行业的生产效率，提高了生产力。除此以外，ARM微处理器及技术还应用到许多不同的领域，并会在将来取得更加广泛的应用,ARM技术在许多不同领域的地位日益巩固。 本文主要是通过对ARM9系列工作原理的描述，继而利用ADS开发软件，在CodeWarrior IDE集成开发环境下编写程序，最后利用编写I2S主函数实现串口设置和初始化，中断，录/放音功能，并通过JTAG仿真，最终在超级终端中查看结果。 【关键词】：ARM, 程序编写,录/放功能 ABSTRACT Develops after the electronic technology, because ARM its volume small, low power loss, low cost, high performance superiority, is developing forward by the astonishing speed, in the industrial control, the expense class electronic products and image formation domains and so on security product, wireless network and communication obtained the widespread application, improved these profession production efficiency enormously, enhanced the productive forces. Except for this, the ARM microprocessor and the technology also apply to many different domains, and will obtain the more widespread application ARM technology in the future to be day by day consolidated in many different domain statuses. This article is mainly through to the ARM9 series principle of work description, subsequently using the ADS development software, in CodeWarrior under the IDE integrated development environment the write program, finally uses compiles the I2S main function to realize the serial port establishment and the initialization, the interrupt, records/the playback function, and through the JTAG simulation, examines the result finally in the super terminal. 【KEY WORD】:ARM, Programming , records/the playback function 目 录 一、引言 1页 二、ARM体系结构介绍 2页 （一）ARM920T硬件平台简介 2页 （二）ARM ADS软件介绍 2页 三、I2S音频接口的设计原 3页 （一）数字音频基础 3页 （二）I2S音频接口 4页 （三）WAV声音格式 5页 （四）I2S调用
