Hi Jose,
Sorry for the late reaction! Yes I have found a solution: to read and stream the data from ADC directly by GPIO pins of the processor. The point is that by direct memory access DMA technique, I could make a direct path from GPIOs to the memories and then I didn't loss any data produced by the ADC. The processors I have used is A20 and the ADC resolution is 16 bits and I could afford the analogue bandwidth of 30 MHz (60 MHz ADC digital speed). You can also use the same strategy I assume. Is it helpful in your case?
Regards,
