摘要： 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。

Abstract: 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.
