摘要：

In this correspondence, various options available for the online computation of discrete cosine transform-IV (DCT-IV) and discrete sine transform-IV (DST-IV) in hardware is considered and compared. A novel architecture for the simultaneous, real-time computation of both the transforms, based on the decomposition of the odd-time, odd-frequency discrete Fourier transform (O-2 DFT), is also proposed.
