realizing exu stream exu block compute phase operation in the unsigned fixed point value domain using modulo overflow behavior that produces condition codes and rounds toward negative infinity
native on: all
Unsigned Fixed Point multiply. Rounds towards negative infinity.
mulufn(uf x, uf y, bit dot) → uf r0
operands: like Identity [xx:x]
