DornerWorks Audio-Video Bridging (AVB) and Time-Synchronized Networking (TSN) IP
Modern warfighters are informed and kept safer on the front lines of battle, industrial systems respond in real-time, and mission-critical sensor systems are connected together in aerospace applications thanks to capable products developed by innovative companies.
Those companies rely on engineering guidance from DornerWorks for the reliable and robust Audio-Video Bridging (AVB) and Time-Synchronized Networking (TSN) solutions to make their product ideas become reality.
DornerWorks AVB IP
By connecting sensors to the leading-edge technology that can make business-critical decisions in an instant, AVB systems developed by DornerWorks are helping manufacturers and other industrial companies adapt swiftly and with confidence.
The FPGA logic in DornerWorks AVB solution was developed for Xilinx FPGAs. As part of the AVB IP, it enables support for multiple types of heterogeneous traffic over a common network to reduce infrastructure costs.
This IP was developed for the most demanding AVB systems, including those requiring defense-class security, so you can be sure it’s right for yours.
1Gbs full-duplex MAC (IEEE 802.3)
IEEE 1722 Data encapsulation for Synchronous and Asynchronous hannels
Automatic gPTP (IEEE 802.1AS-REV; slave-only)
+/- 8 ns accuracy
Rapid time synchronization convergence
High precision packet prioritization and scheduling
RGMII and SGMII interfaces with COTS PHY with MDIO
User-configurable time-based triggers
One PPS output signal with configurable hold-up time
Supports 8 QoS priority levels / traffic classes, each with configurable strict-priority and credit-based scheduler (IEEE 802.1Q-2014)
IEEE 1722 Data encapsulators connect to 3 QOS priority levels, leaving 5 open for other traffic classes
Streaming IP with no packet buffering minimizes latency and maximizes determinism
Xilinx AMBA/AXI4 Lite and Stream interface
DornerWorks TSN IP
TSN standards extend AVB, improving performance and provided performance guarantees with time-scheduled traffic and frame-preemption.
TSN schedules transmissions by adding a timed gate schedule to each class of traffic. The strict priority schedulers only select a queue for transmission if its gate is open, though multiple gates can be open simultaneously.
This IP was developed for the most demanding systems, including those requiring defense-class security, so you can be sure it’s right for yours.
