Abstract
Analysis and architecture design for two major parts of JPEG 2000, discrete wavelet transform (DWT) and embedded block coding with optimized truncation (EBCOT), are presented in this paper. For DWT, a configurable lifting based 1-D DWT core for both 5-3 and 9-7 filters is proposed. Folded architecture is adopted in DWT to reduce the hardware cost and to achieve the higher hardware utilization. For EBCOT, column-based coding architecture of Tier-1 coding with three speedup methods is proposed. Computation time of context formation in EBCOT can be reduced up to 70%.
