I develope iMX7 processor based custom hardware design.
I want to connect high-speed 12-bit ADC with a parallel CMOS output to iMX7dual. The required ADC speed is 60 MSPS and higher. What is the maximum speed that the processor can support receiving 12 data bits, for example, on GPIO1 or GPIO2 and dropping it to eMMC or to RAM? What will be the maximum speed if I would use DMA or if I would use a processor core for these operations?
