IP core (implemented in your own FPGA), embedded module (mounted on your board), expansion card (plugged into a PC), or ready-built equipment (simply installed). Development effort and flexibility differ greatly between them.

Full hardware implementation of zero-recovery-time HSR/PRP redundancy (IEC 62439-3 Ed.4.0). Cut-through forwarding gives very low latency, for power system equipment.

The PDF is the official SoC-e product brochure. It overlaps with the specification table on this page, butthe manufacturer’s official PDF is authoritative, and this page is a summary of it. Where the two differ, the PDF takes precedence; please contact us.
Overview
HPS — HSR/PRP Switch is a soft IP in the SocTek IP core range from SoC-e, aimed at high-availability Ethernet. HSR (High-availability Seamless Redundancy) and PRP (Parallel Redundancy Protocol) are zero-recovery-time redundancy schemes: traffic keeps flowing even when one path fails. They are the standard choice where not even a momentary loss of communication is acceptable, such as power system protection. HPS — HSR/PRP Switch implements this as hardware logic inside the FPGA.
It fits in modest resources, so it can be implemented comfortably even on small, low-cost FPGAs.
Positive ONE Group supports HPS — HSR/PRP Switch end to end: choosing the right option, providing evaluation versions, helping you obtain reference designs, and supply and long-term availability in volume production. We work in English and Japanese.
