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

GRSCRUB: FPGA Configuration Supervisor

The GRSCRUB is an external Field Programmable Gate Array (FPGA) configuration supervisor developed by Cobham Gaisler as an Intellectual Property (IP) core. The GRSCRUB IP features different capabilities, such as programming and scrubbing, which prevents the accumulation of errors in the configuration memory of SRAM-based FPGAs.

Enhancing Ethernet Security with MACsec

Ethernet was originally designed for high-speed data transfer and interoperability between devices. However, traditional Ethernet does not provide built-in mechanisms for securing data traffic, such as encryption or authenticity protection. This is where MACsec comes into the picture.

What Makes Ethernet IP Truly Automotive-Grade

This blog examines what separates truly automotive-grade Ethernet IP from generic implementations across functional safety, time-sensitive networking, security, observability, lifecycle management, and the integration disciplines that only become visible once a program is deep into development.
