TDM Hypercube and TWDM Mesh Optical Interconnections

Two-dimensional arrangement of spatial patterns representing numerical data in input images for effective use of hardware resources in digital optical computing system based on optical array logic

“…The effective use of light's attractive physical properties, such as parallelism, high speed, and crosstalk-free interconnects, has the potential to solve the problems currently experienced in massive data communication, interconnects, and computing. For this reason, optical technology is presently widely used in optical communication, and optical interconnects are actively being researched for future computer systems [9,26,40]. Optical interconnects are fundamental buildingblock of parallel optical computers, and therefore, efficient optical interconnection technologies must be developed before next-generation optical computers can be realized [1,11,30].…”

Routing algorithms on the bus-based hypercube network

“…In this paper, we consider a kind of interconnection networks called the multiple-bus network (MBN) [6], [7], [8], [12], [15], [17], [19], [22], [23], [32], [33], [34]. The MBN is an extension of the single bus network.…”

“…Ishikawa proposed a modified hypercube with multiple buses which used a bypass routing method to reduce the diameter to two [14]. Lee et al [19] proposed the time division multiplexed hypercube (TDM-cube) and the time/wavelength division multiplexed mesh (TWDM-mesh). The TDMcube (N) implements the binary hypercube interconnection among N nodes in log 2 N time slots.…”
