Abstract
In the disclosure, the microprocessor resolves the conflicts in decode stage and schedules the instruction to be executed at a future time. The instruction is issued to an execution queue until the scheduled time in the future when it is dispatched to a functional unit for execution. The disclosure uses a counter for the functional unit to track when the resource is available in the future to accept the next instruction. The disclosure also tracks the future N cycles when the register file read and write ports are scheduled to read and write operand data.
