Abstract: A microprocessor includes a decode unit that maps architectural instructions into micro-operations and dispatches them to a scheduler that issues them to execution units that execute them by reading source operands from a register file and writing execution results to the register file. An architectural instruction instructs the microprocessor to load a constant into an architectural destination register. The decode unit maps the architectural instruction into a load constant micro-operation (LCM) and writes the LCM constant directly to a register of the register file without dispatching the LCM to the scheduler, such that the LCM is not issued to the execution units. In the same clock cycle, the decode unit indicates the LCM constant is available for consumption, such that the LCM imposes zero execution latency on dependent micro-operations and dispatches to the scheduler micro-operations other than the LCM. The register file may include a decode unit-dedicated write port.
