Dtcm cache
http://www.iotword.com/8707.html WebHi All, I am developing an application for the STM32H753II using IAR toolchain, STM HAL and Micrium OS-II. Most of the linker script files in the STM32Cube example suite only specify DTCM RAM for data storage (addresses 0x20000000-0x2001FFFF). I have been using the stm32h753xx_flash.icf (with only DTCM region specified) file with no issues up ...

WebOct 9, 2024 · ITCM: Store the function code that needs to run in RAM DTCM: It is used to store variable data read and written by the kernel, such as stack, and the frequency is consistent with the dominant frequency OCRAM: It is used for general variables, peripheral read-write cache, and the frequency is 1 / 4 of the dominant frequency WebIn my understanding, DTCM, SRAM1 and SRAM2 all offer single cycle access. This leads my to the conclusion, that enabling DCACHE in a situation where there is no slow external memory does not bring any advantage, but the disadvantage of possible cache incoherencies. Is my understanding right? Thanks . #cache #performance #stm32f7 …
