Synopsys Inc. is rolling out the DesignWare Ethernet QoS controller IP that implements the new IEEE specifications for 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 QoS controller, which supports 10/100/1G data transfer speeds, allows designers to develop SoCs that deliver time-synchronized, low-latency audio and video over Ethernet networks with high QoS while retaining compatibility with legacy networks.

"Ambarella experienced great success using Synopsys' DesignWare Ethernet IP for our innovative hybrid camera SoC platform," said Chan Lee, VP of engineering at Ambarella. "The high-quality DesignWare Ethernet IP solution is clearly the best we have used, providing advanced features, high performance and the smallest silicon area. By providing the new Ethernet QoS Controller IP with support for the audio video bridging feature, Synopsys continues to demonstrate its technology leadership in this space."

The configurable DesignWare Ethernet QoS controller provides low power consumption by supporting the IEEE 802.1az (Energy Efficient Ethernet) specification and improved network performance by easing server bottlenecks through multiple TCP/IP offload functions. The controller IP also packs programmable PHY interface, which enables easy connection to all industry-standard Ethernet PHYs. In addition, it delivers 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.

"As a leader in Ethernet IP, Synopsys continues to develop features and products that support the latest IEEE specifications. 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, VP 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 QoS specifications helps designers deliver a more enhanced and reliable user experience."

The DesignWare Ethernet QoS controller supporting 10/100/1G data transfer rates is available. The DesignWare Ethernet 10/100/1G MAC, 10/100 MAC, 1G/2.5G/10G MAC, Ethernet PCS controllers and Ethernet Verification IP including SystemC models are also available.
