Crypto power consumption using MMCAU vs software lib

My query is about power consumption of k64f MCU for doing crypto functions (e.g. a given mode on AES-128-CCM/GCM). I have a choice of using the crypto function from a software library such as tinycrypt or mbedtls.

Alternatively, I can implement the same function to use MMCAU accelerator.


Which of these two approaches would result in lower energy consumption of MCU?

From power consumption perspective, do the crypto accelerators such as MMCAU on k64f & LTC on kw41z yield better?
