I tried to deploy a model on a new device, with a EFR32MG22C224F512IM40-C which has a Cortex-M33, and I’ve realised that CMSIS-DSP and CMSIS-NN are not being included and I’d like to know how could I use them.
Thanks Project ID:
Could you write what kind of deployment from the Studio you use (C++ Library, SLCC Component)?
Also, what toolchain/IDE do you use for compilation?
As a temporary workaround, try to set these three global defines: EIDSP_USE_CMSIS_DSP=1 EIDSP_LOAD_CMSIS_DSP_SOURCES=1 EI_CLASSIFIER_TFLITE_ENABLE_CMSIS_NN=1
I used the C++ library, and I did define those three global defines, but what I dont understand is why using those defines or not the inference time is always the same. The toolchain is GNU ARM v10.3.1 and I’m using the Simplicity Studio v5 as IDE.
I found out that it is due to the option of take log of spectrum, it causes to not have an impact between using or not CMSIS-DSP. I’m not sure if it is due to my processors specification so if anyone knows why could it be or could give me a hint I would be very grateful.
Hi I dont know what i did, but now it seems to be working correctly with new project and CMSIS-DSP now works correctly, maybe it could be that in this case i defines the __ARM_FEATURE_DSP=1.
Thanks for the answers
