The Design And Realization Of Embedded Audio On Demand System

Embedded audio on-demand system by the widespread concern in recent years. The system is designed for five-star hotels, VIP clubs, high-end residential design, customers can be in each room to hear high-quality, high-fidelity stereo music, and each room can be independent, intelligent, personalized control and operation, an independent regulator such as bass and high volume, select audio and music player mode, set the timer switch machine different time, different selection of tracks, when the corresponding telephone access to the room automatically reduces the volume and so on, and each family according to their actual choose the ideal home based music, the enjoyment of modern technology can bring high-quality of life in harmony.This article first briefly introduce the embedded audio on-demand system for the status quo, the sources and research issues of major significance, followed by analysis of the applications of the system, compared with the advantages of existing products, further defined the system of the embedded audio on demand the functional requirements. According to the function of the specific needs of the system to study the overall design of the system, including aspects of both software and hardware.The next chapter, chapter two discusses in detail the hardware design and software design. Hardware design details of the host system and the extension system theory, system architecture and circuit blocks, software design program detailed information on the host system and the extension of the software system-level structure, the transplanting process flow and application software implementation.Finally, the system functionality and performance testing and assessment, the basic functions of the system, performance is relatively stable, reaching the desired results.
