speculable  exu stream  exu block  compute phase   operation   in the signed fixed point value domain   using modulo overflow behavior   that produces condition codes and rounds use current dynamic rounding mode

native on: all

Signed Fixed Point multiply. Uses current dynamic rounding mode.

mulsf(sf x, sf y, bit dot) → sf r0

operands: like Identity [xx:x]


Core In Slots Latencies
Tin E0
