Abstract
Embodiments related to fetching instructions and alternate versions achieving the same functionality as the instructions from an instruction cache included in a microprocessor are provided. In one example, a method is provided, comprising, at an example microprocessor, fetching an instruction from an instruction cache. The example method also includes hashing an address for the instruction to determine whether an alternate version of the instruction which achieves the same functionality as the instruction exists. The example method further includes, if hashing results in a determination that such an alternate version exists, aborting fetching of the instruction and retrieving and executing the alternate version.
