Abstract

The need for on-chip bus protocols are increased drastically for efficient and lossless communication among large number of IP cores of SOC design. This paper proposes a high-performance, highly scalable, bus- independent interface between IP cores named as Open Core Protocol-International partnership. The Open Core Protocol (OCP) is a core centric point to point protocol which provides lossless communication and 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 .In this paper, the most efficient bus architecture was adopted to support most advanced bus functionalities including simple transactions, burst transactions, pipelined transactions, and out-of-order transactions with respect to its suitable application in the real time product. The Open Core Protocol (OCP) was designed and the hardware modeling for that architecture was done using VHDL. This design is Simulated and Synthesized. An experimental result shows the efficiency of the proposed bus architecture and interface.
