Abstract:On the problem that the hardware overhead of hardware implementation architecture for discrete wavelet transform wastes a lot, on the basis of flipping structure, we propose a high performance hardware implementation architecture. The architecture merges the lifting step and adopts the pipelined design to adjust the primitive data path. The proposed 2-D DWT architecture consists of four parts: column filter module, 2×2 transposing module, row filter module and scaling module. The column filter and row filter p… Show more
