Abstract
An exemplary packet processing apparatus where a large number of comparisons can be made concurrently in bit-parallel fashion by partitioning the comparison functionality to two optoelectronic integrated circuits, and interconnecting the two circuits using free space optics. Illustratively, different embodiments are used to perform one-to-many or many-to-one comparisons by developing multiple copies of one value for concurrent comparison with many possible values. The invention is more generally applicable to other comparison applications where one-to-many or many-to-one comparisons are made.
