摘　　要：SOPC是SOC技术和可编程逻辑技术结合的产物,是一种特殊的嵌入式系统。本文介绍了运用SOPC技术,快速构建合适的硬件系统,以Altera公司的NIOS Ⅱ软核和VS1003实现一个MP3播放器的方法。CF卡应用空间广阔,是一种成本低的存储设备,本系统以CF卡为存储介质。在CF上,设计和实现了FAT16文件系统,这一文件系统支持长文件名文件的读写操作,有效的解决了MP3播放器使用传统的8.3格式文件名所存在的问题。最后讨论了FPGA实现行列矩阵键盘驱动的方法。SOPC,a product of the combination of SOC technology and programmable logic technology , is a special kind of embedded systems. This paper introduces the use of Altera SOPC technology to the NIOS Ⅱ soft core and VS1003 achieve an MP3 player method. CF card applications is vast, and is a low-cost storage devices, the system for the CF card storage medium. We design and implement the FAT16 file system Based on Compaetflash Card. File system that supports long file names and an effective solution to problems in MP3 player by using the traditional 8.3 format. Finally, it discusses the realization of the ranks matrix keyboard-driven approach by FPGA.
