Fenglin-I: an open-source TSN chip for scenario-driven customization*

In most distributed hard real-time scenarios (e.g., industry, aerospace), customizing a Time-Sensitive Networking (TSN) chip is critical for meeting their differentiated requirements. In order to provide flexible customization capacity (e.g., traffic workload, I/O integration), we propose an open-source TSN chip architecture namly Fenglin, which contains two basic features for scenario-driven customization: (1)modular cut-through switching architecture, (2)fine-grained forwarding abstraction. Targeting the typical aerospace scenario, we prototype the Fenglin-I TSN chip based on Fenglin architecture and build a ring topology network to demonstrate the correctness and performance of this chip.
