Abstract:
A method of expanding a conditional instruction having a plurality of operands within a pipeline processor is disclosed. The method identifies the conditional instruction prior to an issue stage and determines if the plurality of operands exceeds a predetermined threshold. The method expands the conditional instruction into a non-conditional instruction and a select instruction. The method further executes the non-conditional instruction and the select instruction in separate pipelines.
