Zusammenfassung: | A compare circuit for comparing a first data word with a second data word includes a plurality of sub-circuits, each having a two-bit static compare stage and a dynamic complex logic stage; a dynamic compare node responsive to respective outputs of the sub-circuits; and an output latch that captures a comparison result in accordance with a logic state of the dynamic compare node. In an exemplary embodiment, a local clock generator provides a single controlling clock signal for clocking the output latch, precharging of the dynamic compare node, and clocking of the dynamic complex logic stage of the sub-circuits. |
