BFCVT Multi-vector floating-point convert from single-precision to packed BFloat16 format Convert to BFloat16 from single-precision, each element of the two source vectors, and place the results in the half-width destination elements. This instruction follows SME2 floating-point numerical behaviors corresponding to instructions that place their results in one or more SVE Z vectors. This instruction is unpredicated.
