Overview

The GRETH is a 10/100 Mbit/s Ethernet MAC controller IP with AMBA host interface

The GRETH core implements a 10/100 Mbit/s Ethernet Media Access Controller (MAC) with AMBA host interface. The core implements the 802.3-2002 Ethernet standard. Receive and transmit data is autonomously transferred between the Ethernet MAC and the AMBA AHB bus using DMA transfers.

Key features

  • Full implementation of IEEE 802.3-2002
  • 10/100 Mbit operation
  • AMBA AHB host interface with DMA
  • Low CPU overhead
  • Low area: 1,500 LUT or 10,000 gates
  • Optional PHY control (MII)
  • Optional fault-tolerance for aerospace app.
  • Standalone AHB or GRLIB plug&play interface
  • Drivers for eCos, RTEMS and Linux
  • Free VHDL source code under GNU GPL license
  • Low-cost license for commercial applications

Three Ethernet Design Challenges in Industrial Automation

As factories, process plants, and robotics platforms become increasingly intelligent and interconnected, the demand for stable, low-latency data links has pushed Ethernet deeper into embedded systems. However, since designing Ethernet connectivity into industrial chips comes with its technical and logistical hurdles, engineers may face challenges when implementing Ethernet in industrial designs.

Powering Scale Up and Scale Out with 224G SerDes for UALink and Ultra Ethernet

At the recent ECOC 2025 conference in Copenhagen, Cadence showcased its key role in enabling the future of AI infrastructure with live silicon demonstrations of several essential IP technologies for emerging 800G and 1.6T networks. Powered by Cadence's 224G SerDes IP, Cadence's Ultra Accelerator Link (UALink 1.0) scale-up and Ultra Ethernet scale-out networking solutions deliver the performance, flexibility, and interoperability needed for next-generation AI factories and hyperscale data centers.

Ultra Ethernet Security: Protecting AI/HPC at Scale

As artificial intelligence and high-performance computing (AI/HPC) reshape industries, the need for robust, scalable, and secure connectivity has never been greater. Built from tightly integrated CPUs, GPUs, and SmartNICs, today’s compute clusters demand high-throughput, low-latency networks that can scale from die-to-die to multi-rack deployments.
