A Discrete Fourier-Cosine Transform Chip [PDF]
IEEE Journal on Selected Areas in Communications, 1986 An 8-point Fourier-cosine transform chip designed for a data rate of 100 Mbits/s is described. The top-down design is presented step by step, including algorithm modification for VLSI suitability, architectural choices, testing overhead, internal precision assignments, mask generation, and finally, verification of the layout.
