How to interface 1 MSPS ADC with processing module?

Hello everyone, I have DE1-SoC board which contains 1 MSPS ADC, I am trying to take samples from ADC and process them. ADC Controller clock is 20 MHz and data is available every 16 clock cycles...

But I think that will limit the processing speed to 20 MHz again, right?

What do you mean by 'sharing resourse'?

Your logic is running rocket high at 100MHz so every one clock period of 100 you get 1 sample of ADC. you got 99 left and can be used for whatever purpose.

If your 100 clk is unrelated to adc clk then you need dc fifo else you don't.
