Abstract

In a particular embodiment, a method includes identifying one or more way prediction characteristics of an instruction. The method also includes selectively reading, based on identification of the one or more way prediction characteristics, a table to identify an entry of the table associated with the instruction that identifies a way of a data cache. The method further includes making a prediction whether a next access of the data cache based on the instruction will access the way.
