Peak RAM and Peak Flash measurement for AI model
Hi team,
Reposting my earlier query as it appears to have been missed.
How do I measure the peak RAM and peak Flash usage of an AI model?
I need to calculate peak RAM and peak Flash from the IDE, but the model generated by ST Edge AI is in HEX format and is not included in the IDE's reported size. So, I'm adding the HEX file size to the IDE's peak RAM and peak Flash figures — is this approach correct? Details are shared below.
KWS cpu+npu
IDE
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 -
Total Peak Ram and Peak Flash
- Peak RAM = (103,656 + 22,065 = 122.77 KB)
- Peak Flash = (207,020 + 22,065 = 223.72 KB)
