DesignWare Ethernet Quality-of-Service Controller IP

The DesignWare Ethernet QoS Controller IP is designed to support high-performance applications requiring audio video bridging including the new Time Sensitive Networking (TSN) standards, data center bridging, and advanced segmentation offloading features such as automotive In-Vehicle Infotainment (IVI)/Advanced Driver Assistance Systems (ADAS) chips, set-top box chips, and network routers. This offloading is accomplished by removing any latency associated with configurable IP.

Typical design of configurable IP results in multiple layers that are bridged during configuration. Using multiple layers results in many unnecessary latencies due to double buffering of data as it crosses from one layer to another. The coreConsultant configuration tool removes the latencies at configuration time, thus providing high-performance IP.

The DesignWare Ethernet IP solutions consist of configurable controllers and silicon-proven PHYs supporting speeds of up to 100G, verification IP, IP Prototyping Kits, Software Development Kits and Interface IP Subsystems.
