Abstract

The binary optoelectronic cellular hypercube (CH) [1] was proposed to improve the interconnection performance of mesh-connected arrays of processors. A mesh-reduced CH (M-RCH) [2], combining the mesh for short distance connections and a reduced set of the CH interconnects, was shown to outperform the CH, by reducing the number of clock cycles per data shift. We present in this paper a generalized optimal cellular interconnection (OCI), which simultaneously minimizes the optical fan out and the number of clock cycles per data shift. Our design optimizes the allocation of the optical link distances, minimizes the optical fan-out (for efficiency and ease of design of the optical interconnect), makes use of the electronic mesh where it is more efficient than the optical interconnect, and shows a theoretically proven minimum latency.
