The Constant Multiplier FFT

Also Available Domains DSP Core|Xilinx ISE

Project Code :TVPGTO634


In this project, we are designing a constant multiplier architecture which will be used in the FFT implementation based on the radix considered. The existing multipliers are based on different types such as variable multipliers, or Cordic based multipliers etc. these cordic based multipliers are nothing but rotators which are very simple to utilize but the problem is considering of number of iterations to be consider. Here in this suggested multiplier we are fixing the multiplier to perform a particular operation based on the twiddle factor considered and thereby we can extract the efficiency of the multiplier and thereby it will influence the efficiency of the FFT. The paper explores the 16 point 4-parallel and 8-parallel CM DIF FFT, which calculates the FFT entirely by using constant multipliers. Along with them here we are also implementing the 16 point 4- parallel DIT FFT.
