Description: 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 default in every Windows). Includes a testbench that takes an uncompressed PCM 16 bits Mono WAV file and outputs an IMA ADPCM compressed WAV file.
Compression ratio is fixed for IMA-ADPCM, being 4:1.

Description: 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_Systhesizer,使用FPGA来做电子琴，要用FPGA来做合成器的看这个。
国内部分地区的网络对TERASIC封杀，原因不明，这个包是使用代理下载的，非常不容易。-ALTERA Nios II Embedded Evaluation Kit development board manufacturers (terasic) to provide multi-media display boards (Terasic Multimedia Touch Panel Daughter Board (MTDB)) the expansion of the development package. Where for example there are two open source 1.MTDB_SD_Card_Audio, from the SD card and then read the WAV file to play through the DA, the SD Card for the beginner is not very useful, we can see that the use of FPGA SPI read and write to SD CARD. 2.MTDB_Systhesizer, the use of FPGA as organ, synthesizer use FPGA to do the look at this. Internal parts of the network to block TERASIC for reasons unknown, the package is downloaded using a proxy, is not easy.
