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 positive infinity

native on: all

Unsigned Fixed Point multiply. Rounds towards positive infinity.


mulufp(uf x, uf y, bit dot) → uf r0

operands: like Identity [xx:x]
