Ethernet TSN MAC 10G/25G
Overview
Comcores TSN MAC 10G/25G provides a complete IEEE 802.3 Ethernet Layer 2 solution with support for key TSN features including 802.1Qbu Preemption and 802.3br Interspersing Express Traffic. This enables the use of the MAC in high speed time-critical applications.
The MAC-core performs the Link function of the 10G/25G Ethernet Standard and is a low latency cut-through implementation, while keeping size at a minimum.
The core is fully configurable and interfaces easily to 10G/25G PCS, and can optionally include IEEE 1588 Timestamping Unit (TSU).
The Ethernet MAC Core, on the Client side, implements a 64-bit AXI-S interface for Express and Preemptable traffic respectively while having a standard 64-bit XGMII interface on the PHY side.

Daniel Dik Sep 14 2022, 5G provides a range of improvements compared to existing 4G LTE mobile networks in regards to capacity, speed, latency and security. One of the main improvements is in the 5G RAN; it is based on a virtualized architecture where functions can be centralized close to the 5G core for economy or distributed as close to the edge as possible for lower latency performance. The functional split options for the baseband station processing chain results in a separation between...
