PARIS The Open Core Protocol International Partnership (OCP-IP) announced the release of the OCP 3.0 specification.
This version, OCP-IP claimed, includes extensions to support cache coherence and more aggressive power-management, as well as an additional high-speed consensus profile.
The purpose of the OCP 3.0 specification coherence extensions is to enable hardware-based coherence among the various heterogeneous CPUs, DSPs, accelerators and streaming input/output devices that characterize advanced SoCs.
OCP 3.0, OCP-IP added, defines a new connection protocol that allows the power management hardware to disconnect the OCP interface without losing any transaction so the manager may then independently shut off power.
The work on OCP 3.0 was achieved by members of the OCP-IP Specification Working Group including MIPS Technologies, Nokia, Sonics Inc, Texas Instruments, Toshiba and other industry leading companies.
The OCP 3.0 specification was opened for member review in May.
