How to use CMSIS NN library in MCU xpresso IDE?

Hi.

I am trying to use CMSIS NN library on Keil MCB 1800 board with MCU Xpresso IDE.

For CMSIS-DSP I kow how to use the .a libary but for CMSIS NN there is no .a libary from LPC Open.

As a result if I try to import the files from Github for CMSIS NN in MCU xpresso IDE, it gives me many undefined function errors.

Can someone suggest me how to use the CMSIS NN library with MCU Xpresso IDE?

Thanks#

Hello,

Hope you are doing well. I recommend to check the following page that describes the CMSIS-NN and the support for it. It states that it should be high performance cores like the cortex-M7.If you want to use these libraries I would recommend to upgrade to the i.MXRT family for example the link below.

I.MXRT1050

Hope it helps.

Best Regards,

Sabina

Dear Sabina,

thanks for your reply.

but aren’t there any precompiled versions of Cmsis NN that i can import in MCU xpresso Ide like the CMSIS DSP?

I need to use it on the CortexM3 board only.

What can I do for this?

thanks
