Abstract
Fast Hadamard transforms (FHT) are implemented using a pipelined architecture having an input stage, a processing stage, and an output stage, the FHT having a single internal loop back between the output stage and the input stage, the processing stage having at least one Hadamard processing unit. The FHT implementations provided both forward and inverse transformations, and, lossless normalized and lossfull unnormalized transformations, while the FHT implementation includes only multiplexers, demultiplexer, latches, and shift registers, and while, the processing unit stage includes processing units using only shift registers and effective adders, for fast, low power, and low weight Hadamard transform implementations.
