Overview

The 10Gbps 32-bit Ethernet IP solution offers a fully integrated IEEE802.3-2008 (802.3ae) compliant package for NIC (Network Interface Card) and Ethernet switching applications. This extremely low latency solution is specifically targeted for demanding financial, high frequency trading and HPC applications.

Key features

  • Implements the full 802.3 specification with preamble/SFD generation, frame padding generation, CRC generation and checking on transmit and receive respectively.
  • Implements 802.3bd specification with ability to generate and recognize PFC pause frames.
  • Implements reconciliation sublayer functionality with start and terminate control characters alignment, error control character and fault sequence insertion and detection.
  • Multiple user interface options for the MAC data path; AXI-4 streaming or Avalon Streaming; 32-bit data path 312.5MHz or 64-bit data path 156.25MHz
  • PCS layer XGMII interface implemented as 64-bit (single data rate) SDR interface at 156.25MHz for direct interface to 10GBase-R, XAUI and RXUAI cores
  • Deficit Idle Count (DIC) mechanism to ensure data rates of 10Gbps at the transmit interface.
  • Optional padding of frames if the size of frame is less than 64 bytes.
  • Implements fully automated XON and XOFF Pause Frame (802.3 Annex 31A) generation and termination providing flow control without user application intervention. Non PFC Mode only.
  • Pause frame generation additionally controllable by user application offering flexible traffic flow control.
  • Support for VLAN tagged frames according to IEEE 802.1Q.
  • Support any type of Ethernet Frames such as SNAP / LLC, Ethernet II/DIX or IP traffic.
  • Discards frames with mismatching destination address on receive (except Broadcast and Multicast frames).
  • Programmable Promiscuous mode support to omit MAC destination address checking on receive path.
  • Optional multicast address filtering with 64-bit HASH Filtering table providing imperfect filtering to reduce load on higher layers.
  • CRC-32 generation and checking at high speed using Galois field multipliers and alternate polynomials.
  • Programmable frame maximum length providing support for any standard or proprietary frame length (e.g. 9K-Bytes Jumbo Frames).
  • Optional internal XGMII Loop-back.

Benefits

  • low logic utilization
  • Extremely low latency Tx=41.6ns; Rx=76.8ns

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.
