Abstract

A "slow" signal is not sent across chip to be combined with combinatorial logic, but rather, the logic with which it would be combined is partitioned such that there are two outputs, one if the "slow" signal would be true and a second if the "slow" signal would be false. Both of these outputs are then provided to a multiplexer. The original "slow" signal selects the correct signal, thus saving the interconnect time delay. The concepts also apply to combinations of multiple "slow" signals.
