Abstract
An optical crossbar interconnected signal processor, proposed previously, is reviewed. The ability to implement difficult-to-parallelize algorithms on this processor with reasonable efficiency is illustrated using optimal least square filtering. An inverse filter for removing the effects of a ringing source from reflected data is used as an example. A large number of Toeplitz matrix equations must be solved to determine the optimum inverse filter length and phase. Efficient parallel computation is required. Equations for Levinson's algorithm are provided and an implementation on the optical system is suggested. Performance estimates suggest that interleaving may he used to improve efficiency from 5% to approximately 30%.
