摘要：Fully–pipelined simple modular structures arepresented in this project for efficient hardware realization ofDiscrete Hadamard transform (DHT).From the kernel matrixof HT three different pipelined modular designs are derivedfor transform length N=4.It is shown further that the HT oftransform length N=8 can be obtained from two 4-point HTmodules, and similarly, the HT of the transform length N=16can be obtained from four 4-point HT modules.Higher –length transforms can be obtained from these short lengthmodules as N-point transforms can be computed from 2Mnumber of M point HT-modules, where M=N1/2.The proposedarchitectures are coded in Verilog, simulated by Xilinx ISE toolfor validation and testing and may be synthesized thereafter tobe implemented in FPGA device, Spartan-3 and theperformance will be compared with the one of the presentstructures.
