Incorporating dual Ethernet ports, AVB-DC endpoints may be connected together in a line, reducing installation effort and infrastructure cost, whilst still maintaining the high QoS provided by the AVB standards. Powered by xCORE™ flexible multicore microcontrollers, the AVB-DC reference software is configurable. This allows you to choose the number of streams and audio channels, sample rate and interfaces to external devices. It is even possible to integrate DSP processing and housekeeping functions using spare logical processing cores, providing a compact yet complete solution for a wide range of audio applications. Thanks to the maturity and wide-spread adoption of the XMOS AVB solution and active participation in AVnu plugfests, our AVB-DC endpoint delivers the compromise-free audio networking promised by AVB. Backed up by our flexible hardware platform called sliceKIT, xSOFTip software IP blocks, comprehensive documentation and examples, the AVB-DC solution offers the easiest way to implement your AVB enabled audio product. AVB Audio Daisy-Chain Platform PRODUCT BRIEF ARCHITECTURE APPLICATIONS The AVB-DC design consists of a dual Ethernet MAC with packet forwarder, audio subsystem, network & media clock management and system control. XMOS AVB audio endpoint solutions allow flexible star and/or chain network topologies and are ideal for many applications, such as: All functions, including the network, clocking and audio interfaces, are implemented as software IP running on logical cores inside the xCORE device; allowing for system customisation using C.    Line array speakers Conference microphones Wireless base stations Talker Listener 8ch Talker 2 ch Listener 2 ch AVB Switch IP device Talker Listener 4ch IP device Talker Listener 4ch Talker Listener 16ch AVB Talker Listener 4ch Feature Benefit AVB standard compliant endpoint Plug-and-play operation AVnu plugfest proven interoperability with other vendors Multi-channel audio input and output Digital and analogue audio formats Ideally suited for networked audio applications, such as: professional audio, conferencing or automotive Powered by xCORE multicore microcontroller Flexible, deterministic and responsive processing power Single device multicore microcontroller – low system BoM Flexible hardware & software platform Predefined feature set reference software Easily customisable to meet specific product requirements Source code reference software Integrated development tools suite Rapid development and code reuse Royalty-free deployment.
