A High Speed VLSI Architecture for Computation of 2D-Discrete Wavelet Transform
Subscribe/Renew Journal
This paper proposes a method for the design of a high speed VLSI architecture for the computation of 2D discrete wavelet transform on a 256 256 image. To achieve the goal of high speed, the computational task of multi decomposition levels are optimally mapped to the stages of the pipeline and synchronized. The 2-D filtering operation is divided into four subtasks which are performed independently in parallel. To validate the proposed scheme, a circuit is simulated and implemented using Verilog HDL in Xilinx ISE 10.1 on Spartan-3E FPGA board.
