TSN-SE: TSN Ethernet Switched Endpoint Controller
"The TSN-SE is a highly configurable two-port Switched Endpoint Controller IP core tailored for Time-Sensitive Networking (TSN) Ethernet systems. It embeds hardware support for 802.1AS-2020 timing synchronization, 802.1Qav/Qbv traffic shaping, 802.1Qbu/802.3br frame preemption, plus two low-latency Ethernet MACs. Optional modules enable enhanced reliability with 802.1CB frame replication and elimination, and 802.1Qci per-stream filtering and policing.
Designed for daisy-chained or ring topologies and bridged endpoints, TSN-SE delivers precise, deterministic ingress/egress latency via cut-through switching and minimal buffering, simplifying time-aware application development. It provides real-time timing data timestamps, alarms, and allows dynamic traffic-shaping configuration.
Integration is seamless via standard AMBA® interfaces: a 32-bit APB bus for control/status, and 32-bit AXI-Streaming for packet I/O. Optional DMA engine and software stacks are also available.
