Accellera Systems Initiative (Accellera) is a standards organization that supports a mix of user and vendor standards and open interfaces development in the area of electronic design automation (EDA) and integrated circuit (IC) design and manufacturing.

In June 2009, a merger was announced between Accellera and The SPIRIT Consortium, another major EDA standards organization focused on IP deployment and reuse.

OCP was the first fully supported, openly licensed, comprehensive, interface socket for semiconductor intellectual property (IP) cores.

The mission of OCP-IP was to address problems relating to design, verification, and testing which are common to IP core reuse in "plug and play" system on a chip (SoC) products.

Design teams developing consumer, data processing, telecom (wireless or wired), datacom and mass storage applications can gain significant benefits from the OCP-IP solution.
