Abstract
A data processing apparatus and a method are disclosed. The data processing apparatus comprising: a prediction cache to store a plurality of prediction entries, each defining an association between a prediction cache lookup address and a predicted behaviour; prediction circuitry to select a prediction entry based on a prediction cache lookup of the prediction cache based on a given prediction cache lookup address and to determine the predicted behaviour associated with the given prediction cache lookup address based on the selected prediction entry; and a candidate prediction buffer to store a plurality of candidate predictions each indicative of a candidate prediction entry to be selected for inclusion in a subsequent prediction cache lookup, wherein the candidate prediction entry is selected in response to a candidate prediction lookup based on a candidate lookup address different to a candidate prediction cache lookup address indicated as associated with a candidate predicted behaviour in the candidate prediction entry.
