Hello! Can anybody explain how to calculate SDRAM memory bandwidth, please? One example.

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. -Hannibal-

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.
