Hi,

On those CPUs, the AES implementation in Mbed TLS is pure C, it doesn't use any hand-written assembly. The only platforms where it does so so far are x86-64 (to take advantage of the AES-NI extension if available), and some Via CPUs (x86) that have AES acceleration as well.

Hi,

I hope you are doing well. I am using the mbedTLS AES library in my projects, part of my master thesis at Uppsala University.

I would like to know whether the mbedTLS AES library uses any assemble specific code for operations? I am using this library on Cortex-M23 and Cortex M0+.

Looking forward to hearing from you.

Best regards, Hafiz Areeb Asad
