speculable  exu stream  exu block  compute phase   operation   in the unsigned fixed point value domain   using saturating overflow behavior   that produces condition codes and rounds toward negative infinity

native on: all

Unsigned Fixed Point multiply. Rounds towards negative infinity. Saturating.

mulufsn(uf x, uf y, bit dot) → uf r0

operands: like Identity [xx:x]


Core In Slots Latencies
Tin E0
Copper E0
Silver E0 E1
Gold E0
