STM32F7 with 80MSPS external ADC + DMA + external 10ns SRAM

I need to do ADC sample with a 80MSPS. I have two choice:

 

  1. Using FPGA
  2. Use STM32F7, attach the ADC to the FMC, and using DMA memory-to-memory

 

80MSPS is near the limit of the F7's GPIO speed limit (100MHz, right?)  And I never run the DMA at a speed so high, so anyone can give some suggestions? If I can use F7 to achieve my goal?
