Abstract :
This paper presents an efficient Distributive arithmetic (DA) based parallel processor based architecture to realize 3-Dimensional Discrete wavelet transform (3- D DWT) architecture. Basic DA is modified suitably to employ in 3-D DWT. Parallel processing DA architecture employing modified DA algorithm is designed, modeled and implemented on FPGA. The modified DA reduces the storage space and power consumption by 93% and 4% respectively. The parallel processing 3-D DWT architecture realized using modified DA produces a time delay of 65ns and consumes a power of 108mW. The designed parallel processing based 3-D DWT architecture can be used for video processing applications.
