Memory Efficient VLSI Architecture with High Throughput and Low Latency Image Decomposition Using 3D-DWT

DWT is a well known application of image and video compression technique. A high throughput and pipelined base architecture for lifting multilevel 3-D DWT has been proposed. The redundancies have been removed which resulting from decimated wavelet filtering to maximize the HUE. The proposed structure involves proportionately less arithmetic resources and offers higher throughput rate and also includes local registers and RAM. Compared to the proposed structure it has very small latency compared to the latency of existing structures.DWT is designed based on the lifting scheme using recursive pyramid algorithms for multilevel lifting. The main idea of this architecture is to reduce the area-delay-product of the system by scheduling and partitioning. Hardware utilization efficiency of the design is improved by cascade pipelining architecture.
