VSHA2CL.VV

Vector SHA-2 Compress Low

VSHA2CL.VV vd, vs2, vs1

Performs SHA-256 compression (low 128 bits).

Details

Performs a vectorised SHA 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.

Pseudocode Operation

vd = SHA256_Compress_Low(vd, vs1, vs2);

Example

VSHA2CL.VV v1, v4, v2
