The Open Core Protocol (OCP) delivers the first openly licensed, core-centric protocol that comprehensively fulfills system-level integration requirements. The OCP defines a comprehensive, bus-independent, high-performance, and configurable interface between IP cores and on-chip communication subsystems. A designer selects only those signals and features from the palette of OCP configurations needed to fulfill all of an IP core's unique data, control, and test-signaling requirements. Existing IP cores may be inexpensively adapted. Defining a core interface using the OCP provides a complete description ...
