Overview
TGES is a multi-port, multi-rate managed Ethernet switch with Time-Sensitive Networking (TSN) capabilities.
TGES has a rich set of configurable parameters, both at synthesis time & during runtime, in order to optimize the logic resources footprint attending to the specific user needs. These generics can be configured graphically through the Vivado GUI as well.
The internal micro-architecture includes disruptive enhancements in order to ensure a reliable operation of the switch even in critical use-cases.
All these characteristics enable a wide number of applications/sectors where the use of TGES IP Core is key. Automotive, Marine, Aerospace, Defence or Electric are examples of markets where our customers are already applying this technology.
Key Features
