Abstract

Image compression is one of the major image processing techniques . Discrete wavelet transforms is the most popular transformation technique adopted for image compression. This paper presents an efficient VLSI architecture of a high speed, low power Discrete Wavelet Transform computing. There are number of architectures present for realizing DWT. Based on the application and the constraints imposed, the appropriate architecture can be chosen. Proposed DWT architecture uses DA-DWT scheme that is suitable on FPGA. The architecture has regular structure,simple control flow,small embedded buffers and low power consumption.
