The sine/cosine function generator is based on parallelization of the original CORDIC algorithm by predicting all the rotation directions directly from the binary bits of the initial input angle. Unlike previous approaches that require complicated circuits or exponentially increased ROM, our proposed architecture has a relatively simple prediction scheme(More)
—An efficient implementation of discrete cosine transform (DCT) computations are presented based on the so-called shifted discrete Fourier transform (SDFT), a generalization of the conventional DFT (DFT). Due to the simple form of the factorized matrices, the derived architecture can be easily constructed from the cascade of only two types of parameterized(More)
