Paper Abstract

Realization of a two-dimensional discrete Walsh transform (DWT) by matrix-vector multiplication in an optical architecture is presented. Although data are entered sequentially, the parallelism of optical architecture is exploited in the proposed system and, therefore, the computation time required to obtain the DWT is less when compared to its equivalent electronic system. The hardware realization is achieved with the help of a microprocessor.
