Abstract
Embodiments of the present invention provide a system for balancing a global completion table (GCT) in a microprocessor via frontend steering or stalls. A non-limiting example of the system includes an instruction dispatch unit (IDU) that includes an instruction queue and the system includes an instruction sequencing unit (ISU) that includes a GCT having a first area and a second area. The IDU is configured to determine whether a full group of instructions exist in the instruction queue and to determine whether additional instructions will be received by the instruction queue in a subsequent cycle. The IDU is configured to stall the instruction queue for at least one cycle until a full group of instructions is accumulated at the instruction queue upon determining that additional instructions will be received by the instruction queue in subsequent cycle.
