A STM32F4 platform is used, which has 192kBytes SRAM, which is sufficient for me.
I am trying to build a look up table. The LUT will be used in calculation several times. And I want to put it in SRAM in the process of calculation, instead of FLASH, since reading SRAM is faster than reading FLASH for the core.
And I read this post mentioning putting the LUT in flash, which confuses me.. What should I do to burn the data into flash for the first load and the data will be kept in RAM afterwards for following calculations?
And if anyone knows CCM, is it a good idea to put the LUT in CCM during computation?
