AVnu Alliance and XMOS certify AVB Audio Endpoint Reference Platform

December 10, 2014 // By Graham Prophet
Fabless chip maker XMOS (designer of multicore, deterministic MCUs), and the AVnu Alliance, an industry consortium that aims to drive open standards-based deterministic networking through certification, have announced the first AVnu-certified Audio Video Bridging (AVB) audio endpoint reference platform.

The XMOS software-defined solution has passed all testing for certification and will now bear the AVnu-certified Logo. The XMOS AVB hardware and software reference platform is an affordable, scalable and production-ready solution that allows designers to build a wide range of AVB-enabled audio products, from single speakers and microphones to complex multichannel mixing desks and multi-port conferencing systems.

"AVnu certification reinforces XMOS's leading position in the audio market, adding AVB standards-based networked audio connectivity to our already established USB Audio 2.0 solutions," said Paul Neil, Vice President Product Management, at XMOS. "AVB standards have huge benefits for our customers; by selecting XMOS our customers can add the enhanced functionality that AVB provides and through software development quickly create a portfolio of AVB enabled products. We chose to pursue AVnu certification to provide our customers fast time-to-market with a proven, flexible, scalable networked audio connectivity solution."

Because the AVB functionality of the XMOS audio endpoint reference platform is defined in software, running on the company's family of multicore microcontroller semiconductor devices, engineers can create the exact feature set required for their products. Already in use by companies such as Revolabs and Pivitec, the reference platform enables transport of A/V streams across mixed-use networks with a very high quality of service. Its software-configurable nature also means that it can be used as the basis for multi-standard systems that carry a variety of data types, and interface with a variety of legacy systems, such as CANbus in the automotive and industrial markets.

AVnu Alliance has built testing requirements for products based on the market requirements. AVnu Certification is open for switches and professional audio products at its appointed testing house, University of New Hampshire InterOperability Lab (UNH-IOL). Any member may enter a product into certification testing.
