Abstract : We have discussed the importance of organizing information flow in a manner enabling maximum multiplexing of independent signal paths, leading to a reduction in the number of area consuming longest interconnections, which results in smaller communication area and propagation delays. Among the architectures discussed, the fat-tree is near optimal in this respect. The latter two of the presented architectures provide a natural environment for the joint use of optical and conducting interconnections so as to bring out the best in both and may prove more promising than simple replacement of individual long wires with optics. Optical interconnections are used to provide high density/bandwidth multiplexed information transfer over long distances. Submicron scaled normal conductors are used to provide communications at a density unachievable with optics over shorter distances. This is also consistent with the energetic properties of the interconnection media. Optical interconnections consume less energy per transmitted bit over longer distances compared to normal conductors.
