A recursive algorithm for the discrete Walsh transform is presented which leads to an efficient hardware implementation. The flow diagram of the algorithm constitutes a block diagram for a transform computer requiring only Nlog of N to the base 2 computations where N is the number of input elements. A 16 x 16 two-dimensional Walsh transform computer based upon the algorithm was constructed. The recursive structure of the algorithm allows a hybrid implementation requiring only 256 operational amplifiers, rather than 2048, where each amplifier is used eight times through a feedback loop.
