Hi dmitriev.artyom,

I recommend that you take, as a start, the Hal example ''FMC-SDRAM_DataMemory'' in

http://www2.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-embedded-software/stm32cubef7.html

at this path:  STM32Cube_FW_F7_V1.3.0\Projects\STM32756G_EVAL\Examples\FMC\FMC_SDRAM_DataMemory

Then, you can calculate the time spent using Systick.

That wasn't the question.

The question asks how to calculate the bandwidth based on the configuration options, ie width, cycles, sequential/non-sequential access and functionality of the FSMC from design perspective, not an experimental/observation perspective.
