Simple Open Real-Time Ethernet (SORTE) Device With PRU-ICSS Reference Design


Design files


The TIDEP-0086 reference design implements a Simple Open Real-Time Ethernet (SORTE) master with the Programmable Real-time Unit and Industrial Communication Subsystem (PRU-ICSS). SORTE enables customer applications to exchange process data between the master and devices in a 4-µs cycle time. The design contains open source PRU firmware to enable customer to differentiate their products.

The SORTE protocol includes device discovery, parametrization, PHY and cable delay measurement, synchronization and process data exchange.

  • SORTE device reference implementation
  • Enables 4-µs cycle time to exchange process data
  • PRU firmware provided in source code
  • Fully customizable PRU firmware
