1. A method comprising: dispatching a first operation decoded from an instruction from a dispatch stage of an instruction pipeline to a first queue of a set of execution units of the instruction pipeline in response to there being insufficient resources at the instruction pipeline to execute the first operation, the first operation not available to be picked for execution while stored at the first queue, wherein the first operation is load/store operation, and wherein the first operation is dispatched in response to there not being space available at a third queue of a load/store unit to store the first operation; and providing the first operation from the first queue to a second queue in response to sufficient resources to execute the first operation becoming available at the set of execution units, the first operation available to be picked for execution while stored at the second queue.
