Comprehensive hardware and software TSN capable solution designed for automotive applications
The Ethernet TSN Endstation Controller IP version is envisioned for demanding automotive applications like Advanced Driver-Assistance Systems (ADAS) and autonomous driving with sensors and actuators such as cameras, radars, breaks and steering motors. These applications demand high bandwidth, reliable and secure real-time communication as well as high precision time synchronization. This version supports 10M/100M/1G/2.5G operation and utilizes standard GMII/RGMII/SGMII and MDIO interfaces to communicate with Ethernet Physical layer devices. Its configuration and status register are accessible via a 32bit AXI4-lite bus.
It also includes a multichannel high-performance DMA controller to transfer packets between the network interface and a host processor system. The DMA controller is connected to the host processor system via a memory mapped AXI4 master port.
The Ethernet TSN Endstation Controller IP family from is a comprehensive hardware and software solution for automotive applications. The solution implements Timing & Synchronization (802.1AS), Multiple types of Traffic Shaping (802.1Qav, 802.1Qby, 802.1Qcr), Frame preemption (802.1Qbu), Frame replication & elimination (802.1CB), Steam filtering & policing (802.1Qci), and optional MACsec encryption/decryption (802.1AE).
The solution is designed to provide high-precision time synchronization and accurate traffic scheduling. It supports up to 8 traffic classes, each with a dedicated queue for all ports. It is available in two versions: Ethernet TSN Endstation Controller IP and Ethernet Tiny TSN Endstation Controller IP.
Both versions of the Ethernet TSN Endstation controller IP include a comprehensive software package with device drivers for several operating systems, a software stack for 802.1AS and a complete demonstration system based on Linux.
The solution is available as technology independent RTL source code (System Verilog) or encrypted netlist for ASIC and FPGA implementations. Furthermore, FPGA based hardware platforms are available for evaluation and prototyping.
