QoS controller for streaming AV
01 June 2010
Synopsys has unveiled their latest Ethernet Controller IP with Audio Video Bridging (AVB) features.
The DesignWare Ethernet IP solution supports the new IEEE 802.1AS and 802.1-Qav version D6.0 specifications. These specifications enable efficient networking of streaming audio video (AV) applications through IEEE 802.1 networks found in consumer electronics, automotive AV and professional sound system products. Synopsys' DesignWare Ethernet Quality-of-Service (QoS) Controller, which supports 10/100/1G data transfer speeds, allows designers to develop system-on-chips (SoCs) that deliver time-synchronised, low-latency audio and video over Ethernet networks with exceptional quality-of-service while retaining compatibility with legacy networks.
The configurable DesignWare Ethernet QoS Controller provides:
• Low power consumption by supporting the IEEE 802.1az (Energy Efficient Ethernet) specification
• Improved network performance by easing server bottlenecks through multiple TCP/IP offload functions
• A programmable PHY interface, which enables easy connection to all industry-standard Ethernet PHYs
• Ease of integration by supporting multiple system interfaces such as ARM AMBA 2.0, AHB and AMBA 3 AXI interconnect, allowing designers to easily add Ethernet connectivity to their SoCs
"The DesignWare Ethernet QoS Controller IP enables designers to efficiently support streaming audio video applications such as set-top boxes and network storage," said John Koeter, Vice President of Marketing for the Solutions Group at Synopsys. "As streaming audio video applications become more prevalent in today's devices, the availability of high-quality Ethernet IP supporting the quality-of-service specifications helps designers deliver a more enhanced and reliable user experience."
