摘要
The present invention provides system and method for a group priority issue schema for a cascaded pipeline. The system includes a cascaded delayed execution pipeline unit having a plurality of execution pipelines that execute instructions in a common issue group in a delayed manner relative to each other. The system further includes circuitry configured to: (1) receive an issue group of instructions; (2) determine if a plurality of load instructions are in the issue group, if so, schedule the plurality of load instructions in descending order of longest dependency chain depth to shortest dependency chain depth in a shortest to longest available execution pipelines; and (3) execute the issue group of instructions in the cascaded delayed execution pipeline unit.
