realizing exu stream exu block compute phase operation in the unsigned fixed point value domain using saturating overflow behavior that produces condition codes and rounds use current dynamic rounding mode
native on: all
Unsigned Fixed Point multiply. Uses current dynamic rounding mode. Saturating.
mulufs(uf x, uf y, bit dot) → uf r0
operands: like Identity [xx:x]
