24. Um Algoritmo Bifuncional para Avaliação dos Espectros de Hadamard e Hartley
(A bifunctional algorithm for evaluating Hadamard and Hartley Spectra)

In this paper, a new algorithm for computing the discrete Hartley and Hadamard transforms is introduced,
joining ideas by Hsu-Wu and Guo. A hardware implementation with parallel sums is shown.
