Ethernet Controller
A high-performance, feature-rich network interface solution — integrating DMA, MAC, timestamping, and a full software stack in one ASIC-proven IP core. 10M to 10G, across embedded and enterprise applications.
Overview
An ASIC-proven, feature-rich network interface solution for embedded and enterprise Ethernet connectivity.
The Ethernet Controller delivers reliable, low-latency Ethernet connectivity across a broad range of applications. Comcores offers controllers ranging from 10M to 10GbE, enabling seamless integration into systems requiring Ethernet connectivity at any scale. Designed for scalability, the controller is available with single or multi-port configurations and is fully compliant with IEEE Ethernet standards, ensuring interoperability and long-term product stability.
Optimised for low power and high throughput, the controller supports advanced networking features including IEEE 802.1AS time synchronisation, VLAN tagging, and optional MACsec encryption. With flexible host interface options — PCIe, RGMII, SPI, and integrated DMA engines — and sub-microsecond hardware timestamping, it ensures efficient packet processing for TSN, industrial automation, automotive Ethernet, and audio/video streaming applications.
A comprehensive software package is included: Linux, Windows, and RTOS driver packages with open-source and customisable reference drivers, plus support for TSN and AVB frameworks.

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.
