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

内含AD9957的SPI配置程序，输出为单音。目前该程序仅给出三个寄存器的配置，如有需要，简单阅读程序，即可对程序进行修改，本人项目中使用的为该配置程序，能成功输出各种MPSK波形。-The AD9957 contains SPI configuration program, the output is mono. Currently, the program gives only three registers configuration, if necessary, a simple rea

可以实现通过串口对DDS进行配置，单音模式，输出频率为50M。已经调试过，直接可以使用-Can be achieved via a serial port configuration of DDS, mono mode, the output frequency is 50 m.Have been debugging, can use directly

The AGC is a smart programmable gain amplifier (PGA). The amplifier gain is adjusted based upon the input signal level so that the output is at a specified Target Gain. The AGC can be configured to be either a mono or stereo input / output componen
