基于SOPC的电子音乐相册 摘要：嵌入式系统是当今IT界最热门的概念之一。随着ARM技术的不断推广，如今人们的日常生活中，嵌入式系统的应用早已渗入了其中。可以说嵌入式系统现在已经广泛应用于军事、工业、商业、医疗、个人家庭等的方方面面，并且正在高速发展着。尤其是电子数码产品，其更新换代迅速，从最初的分立元件到现在的集成芯片，产品的体积越来越小，而所展现出来的功能却是越来越强大。本设计采用DE2开发板作为主板，提出了一种基于Nios II的数码音乐相册。主要实现了通过对SD卡存放的音频和图片文件的读取操作，经过构建的Nios处理器控制，将音频信息传送至音频模块播放，将图片信息传送至TFT液晶显示，同时全程使用触摸操作的功能。硬件部分主要负责完成对Nios处理器的构建，音频模块和液晶部分的焊接。软件部分主要负责SD卡、TFT液晶、触摸芯片和音频模块的底层驱动程序以及整个应用程序的编写。通过完成软、硬件的工作，最终实现基于SOPC电子音乐相册的设计。 关键词：SOPC；Nios II；SD卡；TFT液晶；触摸芯片；VS1003音频模块 Smart Home Energy Monitor Abstract：Embedded system is one of the most popular the concept of IT. With the continuous promotion of ARM technology, and now peoples daily life, the application of embedded systems which have already infiltrated. Can be said that embedded systems are now widely used in military, industrial, commercial, medical, personal and family aspects, and it is fast developing. Especially the electronic digital products, and its replacement quickly, which from the initial discrete components to the current integrated chip, and the product is smaller and smaller, but exhibited by the function is more powerful. This design uses DE2 development board as the main board, and presented digital music albums which based on the Nios II. Mainly realized on the SD card through the audio and image files stored in a read operation, after controlling the construction of the Nios processor, the audio information is transmitted to the audio module player, the picture information transmitted to the TFT LCD display, while using the touch operation of the whole Function. Hardware is mainly responsible for the construction completion of the Nios processor, the audio module and the LCD part of the welding. Software component is mainly responsible for SD card, TFT LCD, touch the bottom of the chip, the audio module drivers and write the entire application. Through the completion of hardware and software, finally completed design that the album of electronic music which based on the SOPC. Key words：SOPC, Nios
