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

The goal of this project is to design a MPEG Layer III (MP3) player using a FPGA board. The FPGA will read MP3 source files, decode them into a 16-bit Pulse Code Modulated (PCM) output, and play the audio files through an external speaker.
