In this paper, the implementation of a unified 8 × 8 discrete cosine transform (DCT) and its inverse is described. First, the accuracy of the structure that has been reported earlier is analyzed with Matlab in order to have internal word length requirements for the implementation. Then, the structure is modeled as a data path structure with Synopsys(More)
In this paper, a sequential architecture for 8×8 inverse discrete cosine transform (IDCT) based on row-column decomposition is described. The sequential one-dimensional IDCT kernel is derived by utilizing vertical projection to fast IDCT algorithm. The matrix transposition network is realized with a register-based sequential permutation network and the(More)
