The Open Core Protocol (OCP) is a core centric protocol which defines a high-performance, bus-independent interface between IP cores that reduces design time, design risk, and manufacturing costs for SOC designs.
Main property of OCP is that it can be configured with respect to the application required. The OCP is chosen because of its advanced supporting features such as configurable sideband control signaling and test harness signals, when compared to other core protocols.
The OCP defines a point-to-point interface between two communicating entities such as IP cores and bus interface modules. One entity acts as the master of the OCP instance, and the other as the slave.
Only the master can present commands and is the controlling entity. The slave responds to commands presented to it, either by accepting data from the master, or presenting data to the master.
For two entities to communicate there need to be two instances of the OCP connecting them such as one where the first entity is a master and one where the first entity is a slave.
In this work, the various OCP profiles will be designed using Verilog and the developed design can be used with respect to its suitable application in the real time product. Basically the OCP unifies all inter-core communications.
The OCP's synchronous unidirectional signaling produces simplified core implementation, integration and timing analysis. The OCP readily adapts to support new core capabilities while limiting test suite modifications for core upgrades
