![]() ![]() The application is configured to provide a single Talker and Listener stream of 8 audio channels at up to192kHz sampling rate. It showshow to interface with a high performance audio codec via the I2S library. 1 XM009951ġ00Mbit Ethernet AVB endpoint exampleusing I2S masterThis application note demonstrates an Ethernet AVB endpoint that streams uncompressed audio over anEthernet AVB network with guaranteed Quality of Service, low latency and time synchronization. The example uses various libraries, full details of the functionality of a library can be found in its user guide 2.For descriptions of XMOS related terms found in this document please see the XMOS Glossary 1.Documentation related to these aspects which are not specific to this application note are linked to in the references appendix. This document assumes familiarity with the XMOS xCORE architecture, the IEEE AVB/TSN stan- dards, the XMOS tool chain and the xC language.The firmware was interoperability tested with a Early 2011 MacBook Pro running OS X version 10.10.5. The firmware can be modified to run on any xCORE-200 series device with the required external hardware. The described hardware setup is used for example purposes only. XMOS Audio-pll Slice (XA-SK-AUDIO-PLL - 1v0).XMOS Ethernet Slice (XA-SK-E100 - 1V1).XMOS xCORE-General purpose SliceKit (XP-SKC-XL216 - 1v1).lib_i2s (>=2.0.1) Required hardware The application note is designed to run on the following hardware :.The application depends on the following libraries: The example also shows plug-and-play multichannel recording and playback with Apple Mac hardware running OS X 10.10.5 Required tools and libraries The code in this application note is known to work on version 14.1.1 of the xTIMEcomposer tools suite, it may work on other versions. The application is configured to provide a single Talker and Listener stream of 8 audio channels at up to 192kHz sampling rate. It shows how to interface with a high performance audio codec via the I2S library.
