Abstract
Methods and reservation stations for selecting instructions to issue to a functional unit of an out-of-order processor. The method includes classifying each instruction into one of a number of categories based on the type of instruction. Once classified an instruction is stored in an instruction queue corresponding to the category in which it was classified. Instructions are then selected from one or more of the instruction queues to issue to the functional unit based on a relative priority of the plurality of types of instructions. This allows certain types of instructions (e.g. control transfer instructions, flag setting instructions and/or address generation instructions) to be prioritized over other types of instructions even if they are younger.
