Download the OCP (Open Core Protocol) Specification


Open Core Protocol (OCP) is a common standard for intellectual property (IP) core interfaces, or sockets, which facilitate "plug-and-play" System-on-Chip (SoC) design. Making complex SoC design more efficient for the widest audience, the industry strongly supports the Open Core Protocol as the universal complete socket standard, regardless of on-chip architecture or which processor cores are featured.

The OCP standard is developed by the OCP-IP Working Group.
