The discrete cosine transform (DCT) is used in place of the discrete Fourier transform (DFT) in a wide variety of audio and image processing applications due to its energy compaction properties which approach those of the optimal Karhunen-Love transform. Previous work in reconfigurable hardware has focused on implementations of 2D 8times8 transforms of the type commonly used in the JPEG and MPEG standards. Several applications for larger DCTs exist, including those involving the extraction of… CONTINUE READING
