This paper presents an efficient VLSI architecture of the 2-D wavelet transform for the adaptive directional lifting (ADL) scheme in image coding. To avoid accumulating errors from irrational wavelet transform coefficients, algebraic integers with appropriate input scaling parameters are used. A two-parallel architecture with zigzag processing of the image stream is used to increase the throughput. In a 45-nm CMOS technology, the synthesis results indicate that the proposed architectures for the Daub-4 and 5/3 wavelets can operate at a clock frequency of about 250 MHz with an estimated throughput of 4 Gb/s. |
