Design Discrete Wavelet Transform using Canonic Signed Digit Technique

Abstract

Conventional distributed arithmetic (DA) is popular in field programmable gate array (FPGA) design, and it features on-chip ROM to achieve high speed and regularity. In this paper, we describe high speed area efficient 2-D discrete wavelet transform (DWT) using 9/7 filter based canonic signed digit (CSD) Technique. Being area efficient architecture free of ROM, multiplication, and subtraction, CSD can also expose the redundancy existing in the adder array consisting of entries of 0 and 1. This architecture supports any size of image pixel value and any level of decomposition. The parallel structure has 100% hardware utilization efficiency.
