摘要：

We discuss the cellular-hypercube optical free-space interconnection architecture and its implementation by two-dimensional smart-pixel optoelectronic cellular arrays. We emphasize the behavior of the cellular hypercube in performing shift-invariant parallel shifts of data, a basic requirement of most single-instruction multiple-data algorithms. We present a time-multiplexing scheme for realizing the cellular hypercube, showing that the communication time is inversely proportional to the number of optical detectors per cell. We also present an improved hybrid interconnection network with improved performance that combines the cellular hypercube and mesh, using optics for the longer-distance connections and electronics for nearest-neighbor connections.
