This instruction is defined by:

Encoding

Synopsis

Performs a BFloat16 multiply-accumulate operation on each element in vector register vs2 with the corresponding element in vector register vs1, accumulating results in vector register vd according to mask vm. This is a widening operation that produces single-precision results.
