dc.description.abstract | This letter proposes an efficient hardware accelerator of one-dimensional (1D) eight-point Loeffler discrete cosine transform (DCT) for small portable devices. For continuous 1D input data streams, the accelerator uses only 13 adders and can calculate one DCT coefficient per clock cycle, which is the optimal throughput for the considered applications. Implementation results show that the accelerator can support real-time encoding of practical video sequences and can be a good alternative for small portable applications. | - |
