This paper presents an efficient architecture for three-dimensional (3-D) Daubechies with transpose-based method for medical image compression.Daubechies 4-tap (Daub4) and Daubechies 6-tap (Daub6) are selected with pipelined direct mapping design technique.Due to the separability property of the multi-dimensional Daubechies, the proposed architectures have been implemented using a cascade of three N-point one-dimensional (1-D) Daub4/Daub6 and two transpose memories for a 3-D volume of N*N*N suitable for real-time 3-D medical imaging applications.The architectures were synthesised using VHDL and implemented on Altera ® Cyclone II (EP2C35F672C6) field programmable gate array (FPGA).An in depth evaluation in terms of area, power consumption, maximum frequency and latency are discussed in this paper.
