基于SOPC的mp3播放器设计

本论文主要从音频播放和SOPC技术的交叉点出发，提出了运用SOPC技术在Altera的CyelonⅡ EP2C35FPGA上构建mp3播放器的设计方案。本设计运用IP复用、软硬件协同、硬件加速等方法，结合实验平台资源特点，构建了基于NiosⅡ软核处理器的mp3播放系统。实现了MPEGⅠ layerⅢ音频解码的流畅播放。该系统具有体积小，设计灵活，开发周期短等优点。

Mp3 Player Design Based on SOPC

This paper mainly from the audio playback and the intersection of SOPC technology, this paper proposes the use of technology in Altera＇s SOPC CyelonlI EP2C35 FPGA mp3 player built on the design.The use of IP design reuse,collaboration software and hardware,hardware acceleration and other methods,combined with the experimental characteristics of platform resources to build a soil-core processor based on NiosⅡ mp3 player system. Achieve MPEGⅠ layerⅢ smooth playback audio decoding.The system has a small size,design flexibility, short development cycle and so on.
