The DesignWare® Ethernet Quality-of-Service (QoS) Controller IP implements the link layer of an OSI Ethernet system. The silicon-proven core is configurable and scalable to meet multiple Ethernet application requirements. Synopsys offers a high-quality IP solution that is in volume production and has been successfully implemented in a wide range of applications.
The DesignWare Ethernet QoS Controller IP is designed to support high-performance applications requiring Audio Video Bridging features such as set-top box chips and network routers. This is accomplished by removing any latency associated with configurable IP. Typical design of configurable IP results in multiple layers that are bridged during configuration. This results in many unnecessary latencies due to double buffering of data as it crosses from one layer to another. The coreConsultant configuration tool removes such latencies at configuration time, thus providing high-performance IP. DesignWare Ethernet Quality-of-Service Datasheet
