Abstract

A method is provided for dynamically determining which instructions from a plurality of available instructions to issue in each clock cycle in a multithreaded processor capable of issuing a plurality of instructions in each clock cycle. The method includes the steps of: determining a highest priority instruction from the plurality of available instructions; determining the compatibility of the highest priority instruction with each of the remaining available instructions; and issuing the highest priority instruction together with other instructions compatible with the highest priority instruction in the same clock cycle. The highest priority instruction cannot be a speculative instruction. The effect of this method is that speculative instructions are only ever issued together with at least one non-speculative instruction.
