基于AMBE-1000的数字化语音存放系统的设计
|
摘要
随着社会上多媒体信息的急剧增长，对信息进行处理和有效存储逐渐成为必须的手段。语音信号作为最常用的信息载体之一，它的处理与存储，也变得越来越重要。数字化语音记录方式以其使用寿命长，存储可靠性高，利用空间有效性高和检索方便等优点，已经取代了传统的模拟方式成为一种趋势，并应用到众多领域和场合。本论文分析了当前几种数字化语音系统解决方案的各自特点，并对目前国内外数字化语音系统的同类产品作了对比，针对一些国内产品系统复杂度高、缺乏适用性、信息存储量不大的缺陷和不足，设计了一种可靠适用的数字化语音存放系统。
设计采用了比较先进的基于AMBE算法的专用语音压缩编／解码芯片AMBE-1000，语音质量好，压缩率高，可以将数字语音信号码率压缩至2.4KB／S，而且编码速率可通过修改控制程序选择。存储芯片选用了大容量FLASH闪速存储器，可以实现语音数据的海量存储。
系统的硬件部分首先分析了整个数字化语音存放系统的组成结构和工作原理，并对所使用的主芯片的工作原理和模式作了必要介绍，在此基础上进行模块化的电路设计，主要分为单片机控制单元、语音编码解码单元、音频数据采集单元、片外存储扩展单元以及其它一些硬件电路。
系统的软件部分主要介绍了下位机的控制程序设计，其中的关键部分是数据发送和数据接收的编程设计。论文中详细讲解了控制程序设计的方案，指出了数据发送程序和数据接收程序设计中的重点和一些需要注意的问题，并给出了程序流程图。
完成了硬件和软件的设计后，进行PCB制板，制成电路板后对其进行硬件调试和系统性能测试，结果显示，系统能够实现较好的语音质量和长时间的语音信息存储，达到设计预期的效果，具有一定的应用价值。
论文在最后总结了所完成的工作，并介绍了本设计的主要特色，同时还分析了整个系统的不足之处，指出了今后努力的方向。
With the rapidly growth of multimedia information in society, it has gradually become a necessary mean to deal with and store the information effectively. Being one of most used information carriers, the voice signal memorization also becomes more and more important. Compared with the traditional simulation ways, the digital voice recording way has omitted the mechanical structure which is easily damaged. It has long life, the high reliability of storage, the high effectiveness of the using space the convenient access and so on. Therefore, the application of the digital voice recording system has become a trend. The thesis analyzes the current several kinds of solution plan of the voice recording system, and compares the present digital voice system products in domestic and overseas. In view of some domestic product flaws, author proposes a reliable and suitable design idea of the digital voice system.
The system adopts an advanced specific speech compression chip based on AMBE algorithm. It can achieve good voice quality and high compression rate at 2.4 Kb/s. The memory chip selected large capacity Flash memory to realize mass memory of the voice data.
The hardware part of the digital voice system firstly analyzes the composition structure and the principle of work, introduces the main chip AMBE-1000 characteristic. In this foundation carries on the modular circuit design, mainly divided into control unit, voice code and decoding unit, audio data acquisition unit, the chip external storage expansion unit and so on.
The software part of the digital voice system mainly introduces the design of control programming, the key is data transmission and receive. The thesis explains the control procedure design mentality in detail, points out some key of the software design and some question to which need to pay attention, and gives the program flow diagrams.
After the hardware and the software design, the thesis introduces the PCB design, then carries on the hardware debugging and the system performance testing after making the electric circuit board, finally draws the conclusion: the system can realize the good voice quality and the long time voice information storage, achieves the design anticipated effect, and has certain market application value.
The thesis finally summarizes the completed work, and introduces the main characteristic, meanwhile analyzes the system deficiency, points out the diligently direction.
