All-optical Linear Array with a Reconfigurable Pipelined Bus System (OLARPBS) optical bus parallel computing model

The All-optical Linear Array with a Reconfigurable Pipelined Bus System (OLARPBS) optical bus parallel computing model is proposed in this paper. The OLARPBS model includes several architectural and logical extensions to the existing LARPBS(p) model. Architecturally, the extensions include the replacement of the electronic processors by fine-grained, all-optical digital processing elements; and the replacement of the optical conduit (optical bus) by one or more optical conduits, each consisting of a structural hierarchy of bundles of light paths that enable multiple parallel and/or pipelined message communications. Logically, the extensions include: parallel and/or pipelined, conduit-based, optical registers; register scheduling; and processor data path requirements. Collectively, these extensions enable register-based bits-in-flight algorithm development. A study of two applications with implementation on the OLARPBS model is considered.
