VAESEM.VV

Vector AES Encryption Middle Round

VAESEM.VV vd, vs2, vs1

Performs a middle AES encryption round.

Details

Performs a vectorised AES cryptographic round operation. Each element group undergoes one step of the cipher algorithm in parallel. See the Zvk vector crypto extension for full semantic details.
