Implementation Of Fully-Pipelined 16-Point DHT Architectures Using 8-Point And 4-Point DHTs for FPGA Realization
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2012, Vol 1, Issue 9
Abstract
Fully–pipelined simple modular structures are presented in this project for efficient hardware realization of Discrete Hadamard transform (DHT).From the kernel matrix of HT three different pipelined modular designs are derived for transform length N=4.It is shown further that the HT of transform length N=8 can be obtained from two 4-point HT modules, and similarly, the HT of the transform length N=16 can be obtained from four 4-point HT modules.Higher – length transforms can be obtained from these short length modules as N-point transforms can be computed from 2M number of M point HT-modules, where M=N1/2.The proposed architectures are coded in Verilog, simulated by Xilinx ISE tool for validation and testing and may be synthesized thereafter to be implemented in FPGA device, Spartan-3 and the performance will be compared with the one of the present structures.
