    fft and cordic IP ,how to pass the data from fft to cordic for finding the phase?

    i m using 512 point FFT IP core in V6 FPGA to calculate the frequency of the input signal, i m getting the correct peak and amplitude for the same . the peak's real and imaginary value i have to give to the cordic ip core(atan) to get the phase of the input signal . the input to the fft is a...

    multiply accumulate IP in FPGA

    i am using the multiply and accumulate IP core from Xilinx ,the operation it performs is first multiply the two inputs a and b and give prod= a*b then it subtracts the previous output from Prod s=s-prod problem: i m not able to see the s(present) output as it is loop back. in chipscope one of...

    dual edge sampling and dual data rate

    hi, are the DES and DDR one and the same thing? if the input frequency is 1GHz then the sample rate will be 2GSPS in both the cases.right?

    layout trace length and phase

    hi all, is there any relation between trace length and phase of a clock signal ? i have to two clock signals of same frequency coming to two devices that should be same in trace length but if there is some difference between the traces then what will be phase difference between the two?
