Wave-Parallel Computing

We investigate wave-parallel computing (WPC) architectures to address the interconnection problems in highly parallel integrated systems. The fundamental concept is frequency multiplexing of signals, which enables us to utilize the parallelism of electrical (or optical) waves for parallel processing. The key to success with WPC architectures lies in finding efficient implementation of multiwave selection function. This research proposes multiwave selection circuits using multi-carrier coherent detection of modulated waves. The proposed method has potential advantages of high degree of multiplexing and real-time-variable selectivity. Also, its applications to the densely connected WPC architecture for massively parallel processing is discussed with emphasis on the reduction in the number of interconnections.
