Title: Enhanced single threaded execution in a simultaneous multithreaded microprocessor

Abstract: A method, system, and computer program product are provided for enhancing the execution of independent loads in a processing unit. The processing unit dispatches a first set of instructions in order from a first buffer for execution. The processing unit receives updated results from the execution of the first set of instructions. The processing unit updates, in a first register, at least one register entry associated with each instruction in the first set of instructions, with the updated results. The processing unit determines if the first set of instructions from the first buffer have completed execution. Responsive to the completed execution of the first set of instructions from the first buffer, the processing unit copies the set of entries from the first register to a second register.
