ABSTRACT:
Multiple register input multiplexors select a respective one of the results generated by operation units, and store the selected results in respective architecture registers as specified by the corresponding instructions (from which the results are generated). A forwarding multiplexor receives the results before the results are provided to the register input multiplexors, and selects one of the results for use as an operand for execution of a dependent instruction. As the forwarding multiplexor receives the results at a point before the inputs of the register input multiplexors, the time duration required to forward the results may be minimized, and a greater instruction throughput performance may be attained in a processor.
