Abstract:
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 at least one load instruction is in the issue group, if so scheduling the least one load instruction in a first pipeline based upon a priority list; and (3) schedule execution of the issue group of instructions in the cascaded delayed execution pipeline unit.
