With rapid growth in the adoption of audio video bridging for audio transport, audio endpoint solutions must be low cost and production ready. To answer this demand, XMOS and Attero Tech have jointly developed a solution that consists of a flexible XMOS software-only implementation of AVB audio and a low-cost board that supports up to 8 duplex channels of audio. The low-cost XCore® XS1-L2 dual-core processor is at the heart of the new, commercial-grade reference design and reduces the cost for AVB endpoints by over 50 percent compared to alternative solutions.
XMOS event-driven processors® bring together the capabilities of processors, DSPs, and FPGAs, yet are programmed via unified design flow in C, XC, and C++. The deterministic architecture of XMOS devices is a perfect match for the low latency, time synchronized nature of AVB. XMOS devices also provide the ability to integrate digital audio interfacing, control functionality using TCP/IP and DSP processing, often required in AVB endpoints such as speakers. The software framework is free of charge with source code available under a royalty free license from XMOS. Additional design services for AVB and audio systems are available from Attero Tech.
