| Abstract: | The paper researched the main problem in the VLSI implementation of lifting scheme 2D-DWT.The design regarded bumping operational speed,economizing hardware resource,ensuring operational veracity and stability as principle.The paper proposed a high efficient VLSI architecture for 2D-DWT by using a lifting-based scheme.Where the fold and Time Division Multiplexing(TDM) technology are adopted to optimize the design of the architecture.The high frequency component and the low frequency component are available alternately. |
| Keywords: | lifting wavelet wavelet transform VLSI |
