Ethernet TSN Bridge
A complete integrated hardware and software subsystem that combines a TSN capable Ethernet switch, DMA engine and IEEE 802.1AS time synchronisation.
Overview
A bridge connects multiple TSN enabled network segments while ensuring deterministic,low-latency communication.
Like a traditional Ethernet switch it forwards frames between ports based on MAC addresses, but it also adds TSN scheduling, filtering, and traffic management for reliable, time-critical communication. Comcores offers a versatile Bridge subsystem IP tailored to a range of performance levels and TSN feature sets which is suited for demanding applications in automotive, industrial, avionics, and defence.
The Bridge subsystem IP integrates hardware and software in one subsystem, connecting to embedded processors through an AXI Memory-Mapped interface for frame exchange and an AXI4-Lite interface for management and configuration.

Omni500 – Configurable evaluation and prototyping platform
The Omni500 is a configurable evaluation and prototyping platform for deterministic Ethernet systems from 10 Mb/s to 1 Gb/s. It combines TSN networking, multi-speed Ethernet interfaces, and field buses into one compact platform for validation, development, and system integration.
Omni500 is built on combining an AMD Artix UltraScale+ FPGA, Linux-capable control processor, and a comprehensive set of interfaces.
Built for engineers who need deterministic results. The platform handles all real-time packet processing and timestamping in hardware, while the Linux control layer provides the flexibility of a full software stack — Web GUI, REST API, and SDK included.

What is TSN?
TSN, or Time-Sensitive Networking, is a technology based on the IEEE 802.1Q standard. It has evolved from the Ethernet technology currently used to carry all types of traffic, for which ethernet was not originally intended, such as multiple data flows with different...
