Design and Implementation for 2 -D IWT using Parallel Computing Units

In this paper,a novel design and hardware implementation using parallel computing for 2-D integer lifting wavelet transform (IWT) is proposed of which input datas are divided into groups, its row and column transform module use parallel computing technology.This design is capable to produce 2 results every cycle,which takes N²/2 time units to finish a N×N 2D IWT.And also,we implemented it in FPGA,the estimated frequency of operation is 394.415MHz.
