Hi,
i have recently bough DE0 nano board and i am beginner in Verilog. I went through the ADC code given in CD and i am comfortable in understanding how the external data is captured using the ADC via SPI interface.
Holistically, i want to capture 8 signals at a sampling frequency of 20-50 kHz and take FFT on them. From the FFT vaues of different signal, i would like to get the information of odd harmonics component by using a for loop and send the final value via SCI to a micro-controller. As the total number of samples are much higher 8*50000, the data points have to be saved in external SDRAM. With my current knowledge i could capture the data and save it in a variable.
I would be really grateful if i get the guidance and opinions from the experts.
Regards,
subash
