Multi-Protocol Industrial Ethernet Detection with PRU-ICSS Reference Design for Industrial Automation Applications

There are currently more than 30 industry standards for Industrial Ethernet in the field of industrial automation. Some mature real-time Ethernet protocols such as EtherCAT, EtherNet/IP, PROFINET, Sercos III, and PowerLink require specialized MAC hardware support for FPGAs or ASICs. The Programmable Real-Time Unit within the Industrial Communication Subsystem (PRU-ICSS) exists as a hardware module of the Sitara processor family and will replace FPGAs or ASICs with a single chip solution. Firmware in PRU-ICSS can be used to detect the type of Industrial Ethernet protocol and load the corresponding industrial application into the Sitara processor during runtime. This TI Design introduces PRU-ICSS's multi-protocol Industrial Ethernet protocol detection firmware.
