Hi Team,
Memory calculations for STM32N6570 DK board.
Peak RAM & Peak Flash Estimation STM Cube IDE
- For CPU only
Peak RAM = .data + .bss
Peak Flash = .text + .data - For CPU+NPU
Peak RAM = (.data + .bss) of application code + (.data) of model hex
Peak Flash = (.text + .data) of application code + (.data) of model hex
.data of model hex needs to be added separately, as the model hex is generated and flashed separately on the STM32N6
From the IDE we get this bss,data,and text size
Flash = text + data = 205,404 + 1,616 = 207,020 bytes ≈ 202.17 KB
RAM = data + bss = 1,616 + 102,040 = 103,656 bytes ≈ 101.23 KB
For cpu+npu we flash the model in hex format, so we need to add the peak ram and peak flash of hex file with IDE peak ram and peak flash.
model size - STEDGEAI 3.0
Total Peak Ram and Peak Flash
- Peak RAM = (103,656 + 22,065 = 122.77 KB)
- Peak Flash = (207,020 + 22,065 = 223.72 KB)
Is my calculation for peak RAM and peak FLASH are correct?
could you please confirm this?
