Some fundamental OCP concepts: Sideband signalling • Moving data between cores: central • Other communication types also important • Different types of control signalling • Dedicated point-to-point data communication • Notification of errors unrelated to address/data transfers • Reporting errors • The error response code in the response field describes errors resulting from OCP transfers that provide responses • Write-type commands without responses cannot use the in-band reporting mechanism • Out-of band error fields • signals report more generic sideband errors, including those associated with posted write commands
