Abstract
A processor includes a prediction table, a prediction logic circuit, and a prediction verification circuit. The prediction table has a plurality of sets, each of the sets has a hot way number, at least one warm way number, and at least one confidence value corresponding to the at least one warm way number. The prediction logic circuit generates a prediction result by predicting if the at least one warm way number is an opened way. The prediction verification circuit generates a correct/incorrect information according to the prediction result, and generates an update information according to the correct/incorrect information. The prediction verification circuit updates the hot way number, the at least one warm way number and the at least one confidence value of the at least one warm way number according to the update information.
