TECHNIQUES FOR SCHEDULING OPERATIONS AT AN INSTRUCTION PIPELINE

A dispatch stage of a processor core dispatches designated operations (e.g. load/store operations) to a temporary queue when the resources to execute the designated operations are not available. Once the resources become available to execute an operation at the temporary queue, the operation is transferred to a scheduler queue where it can be picked for execution. By dispatching the designated operations to the temporary queue, other operations behind the designated operations in a program order are made available for dispatch to the scheduler queue, thereby improving instruction throughput at the processor core.
