摘要:
A design structure embodied in a machine readable storage medium for designing, manufacturing, and/or testing a design for minimizing unscheduled D-cache miss pipeline stalls is provided. The design structure includes an integrated circuit device, which includes a cascaded delayed execution pipeline unit having two or more execution pipelines that begin execution of instructions in a common issue group in a delayed manner relative to each other, and circuitry. The circuitry is configured to receive an issue group of instructions, determine whether the issue group is a load instruction, and if so, schedule the load instruction in a first pipeline of the two or more execution pipelines, and schedule each remaining instruction in the issue group to be executed in remaining pipelines of the two or more pipelines, wherein execution of the load instruction in the first pipeline begins prior to beginning execution of the remaining instructions in the remaining pipelines.
