MP3解码程序在Openrisc开发系统上的实现

Implementation of MP3 Decoder in Openrisc Developing System

介绍了MP3解码器在Openrisc开发系统上实现的过程。Openrisc是源代码公开的32位RISC内核,使用之前经过了严格的仿真、测试。项目中,针对Openrisc系统环境对MP3的解码算法也作了很多优化,最终在下载有Openrisc内核的FPGA上得到验证,放出悦耳圆润的音乐。

This paper introduces the implementation of MP3 decoder in Openrisc developing platform. Openrisc is an open-source and free RISC IP core. So strict testing and simulating are needed before being used. Also, great optimization is done on the decoding algorithm. Finally, the decoding system works well on the FPGA board and can hear smooth music.
