// DESCRIPTION  :       Twiddle factor ROM for 256-point FFT

// FUNCTION:            

// FILES:                        WROM64.v - ROM of twiddle factors.        

//  PROPERTIES: 1) Has 64 complex coefficients which form a table 8x8,

//                         and stay in the needed order, as they are addressed

//                         by the simple counter 

//                                                      2) 16-bit values are stored. When shorter bit width is set

//                            then rounding     is not used

//                                                      3) for FFT and IFFT depending on paramifft
