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 four or more 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) receiving an issue group of instructions; (2) scheduling the instructions in program order received; and (3) executing the issue group of instructions in the cascaded delayed execution pipeline unit. The present invention can also be viewed as providing methods for providing a group priority issue schema for a cascaded pipeline. The method includes: (1) receiving an issue group of instructions; (2) scheduling the instructions in the program order received; and (3) executing the issue group of instructions in the cascaded delayed execution pipeline unit. |
