The categories of line buffer and the strategy to optimize the size of internal memory are also described. For multi-level two-dimensional discrete wavelet transforms, the recursive pyramid algorithm is adopted to turn our proposed architecture into another efficient architecture. According to the comparison results, the proposed architecture outperforms previous arts in the aspects of memory size, control complexity, and flexibility. © 2002 IEEE. |
