ABSTRACT:
Systems and methods are disclosed for updating owner predictor structures. In one embodiment, a multi-processor system includes an owner predictor control that provides an ownership update message corresponding to a block of data to at least one of a plurality of owner predictors in response to a change in an ownership state of the block of data. The update message comprises an address tag associated with the block of data and an identification associated with an owner node of the block of data.
