#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
