Distributed ALUs based on photonic switches

The article examines a photonic network with distributed control, consisting of several nodes connected by a common channel, in which, during the transmission of one number, a single operation is performed on numbers that are transmitted in parallel by all nodes. Such operations as summing or finding the maximum (minimum) of numbers transmitted sequentially across binary bits are considered. It is assumed that the bits of numbers are transmitted by paraphase optical signals, and the common channel is built from photonic switches of these signals.
