This paper presents the design and implementation of distributed arithmetic (DA) architectures of three-dimensional (3-D) Discrete Wavelet Transform (DWT) with hybrid method for medical image compression. Due to the separability property of the multi-dimensional Haar and Daubechies, the proposed architecture has been implemented using a cascade of three N-point one-dimensional (1-D) Haar/Daubechies and two transpose memories for a 3-D volume of NxNxN, suitable for 3-D medical imaging applications. The architectures were synthesised using VHDL and G-code and implemented on field programmable gate array (FPGA) single board RIO (sbRIO-9632) with Spartan-3 (XC3S2000). Experimental results and an analysis of the area, power consumption, maximum frequency, latency, throughput as well as the subjective test are discussed in this paper.
