Abstract

See full text

A method for predicting a way of a set associative shadow cache is disclosed. As a part of a method, a request to fetch a first far taken branch instruction of a first cache line from an instruction cache is received, and responsive to a hit in the instruction cache, a predicted way is selected from a way array using a way that corresponds to the hit in the instruction cache. A second cache line is selected from a shadow cache using the predicted way and the first cache line and the second cache line are forwarded in the same clock cycle.
