摘要： In an approach to processor dependency-aware instruction execution, responsive to a new instruction being issued to an instruction issue queue in a processor, a future dependency count is incremented for each instruction of a plurality of instructions in the instruction issue queue that has a dependency on the new instruction. The plurality of instructions in the instruction issue queue are prioritized based on the future dependency count. The highest priority instruction of the plurality of instructions in the instruction issue queue is issued.
