Abstract
A method for scheduling micro-instructions, performed by a qualifier, is provided. The method includes the following steps: detecting a load write-back signal broadcasted by a load execution unit; determining whether to trigger a load-detection counting logic according to content of the load write-back signal; determining whether an execution status of a load micro-instruction is cache hit when the triggered load-detection counting logic reaches a predetermined value; and driving a release circuit to remove the first micro-instruction in a reservation station queue when the execution status of the load micro-instruction is cache hit and the first micro-instruction has been dispatched to an arithmetic and logic unit for execution.
