An Audio Interface for the Zedboard

Overview

This VHDL interface connects the ADAU1761 audio codec on the Zedboard to the Zynq PL. Audio signals can be received in stereo from the line in jack and/or transmitted to the headphone out jack. The design has originally been developed by Mike Field (alias hamster). In his design it is part of a system for filtering audio signals with the Zedboard (http://hamsterworks.co.nz/mediawiki/index.php/Zedboard_Audio). We have extracted, modified and extended the audio interface part to provide an easy to use standalone IP core for using the audio capabilities on the Zedboard.

Features

• ready to use, standalone IP block
• interface synchronized to 100 MHz system clock
• compatible to Vivado
• testbench to test line in and headphone out
• documentation and "how-to-use" guidance
• ready-to-use bitstreams for quick evaluation
