  • Systems and methods for selectively bypassing address-generation hardware in processor instruction pipelines
    Patent number: 11023241
    Abstract: Systems and methods selectively bypass address-generation hardware in processor instruction pipelines. In an embodiment, a processor includes an address-generation stage and an address-generation-bypass-determination unit (ABDU). The ABDU receives a load/store instruction. If an effective address for the load/store instruction is not known at the ABDU, the ABDU routes the load/store instruction via the address-generation stage of the processor. If, however, the effective address of the load/store instruction is known at the ABDU, the ABDU routes the load/store instruction to bypass the address-generation stage of the processor.
