The OCP captures all core characteristics without restricting system arbitration, address map, etc.

  • Small set of mandatory signals, with a wide range of optional signals.

  • Core-specific data and address widths.

  • Structured method for inclusion of sideband signals: high-level flow control, interrupts, power control, device-configuration registers, test modes, etc.

  • Synchronous unidirectional signaling allows simplified implementation, integration, and timing analysis.

  • Transfers may be pipelined for reduced latency.

  • Optional burst transfers for higher efficiency.

  • Multiple concurrent transfer sequences may be managed with thread identifiers, for out-of-order completion.

  • A connection identifier may be used to provide end-to-end identification for targets desiring to distinguish initiators for service prioritization, etc.

  • OCP is a functional superset of the VSIA's Virtual Component Interface (VCI), adding configurable sideband control signaling and test harness signals.
