In the Cortex-M series (Cortex-M0, Cortex-M0+, Cortex-M1, Cortex-M3, Cortex-M4, Cortex-M7, Cortex-M23, Cortex-M33, Cortex-M35P, Cortex-M52, Cortex-M55, Cortex-M85). Is M-Profile Vector Extension (MVE) available only in Cortex-M55? or is it in other too?
MVE, also known as Helium, is a feature of Armv8.1-M architecture.
It is supported in Cortex-M52, Cortex-M55, and Cortex-M85 today.
