This project features a full-hardware sound compressor using the well known algorithm: IMA ADPCM. The core acts as a slave WISHBONE device. The output is perfectly compatible with any sound player with the IMA ADPCM codec (included by defau

ALTERA Nios II Embedded Evaluation Kit开发板制造商(terasic)提供的多媒体显示板（Terasic Multimedia Touch Panel Daughter Board (MTDB)）扩展开发包。 里为有两个开源的例子 1.MTDB_SD_Card_Audio,从SD卡中读取WAV文件然后通过DA播放，这个对不SD Card的初学者非常的有用，可以知道使用FPGA SPI来读写SD CARD。 2.MTDB_Systhesiz

实现wav解码，用VHDL编写，在quarters下运行，用于FPGA，CPLD稍作修改也可用-Wav decoder implementation using VHDL written to run in the quarters for the FPGA, CPLD some slight modifications can also be used
