May 8, 2006 -- Increasing design complexities in deep sub-micron systems on chip (SoCs) have forced designers to adopt a communications centric approach to cope with the corresponding increase in the design productivity gap. These communications-centric interfaces define a modular socket interface and do not constrain the implementation of the actual SoC interconnect to any particular topology or physical layer.
In this paper we focus on the Open Core Protocol (OCP), one of the first protocols to adopt a non-proprietary, open standards based, on-chip protocol with independence from the physical transport. This independence allows implementers to scale and choose an interconnect topology and parameters which provide commensurate performance to a number of high performance SoCs.
