speculable  exu stream  exu block  compute phase   operation   in the decimal floating point value domain   using saturating overflow behavior   that produces condition codes and rounds to nearest, ties away from zero

native on: Decimal8 Decimal16

Exactly convert a decimal floating point value to a unsigned integer, rounding away from zero and producing saturating result values.


f2uedsfz(d x) → d r0

operands: like Addd [dd:d]


Core In Slots Latencies
Decimal8 E0 E1 d:d=4 dv:dv=4 q:q=5 qv:qv=5
Decimal16 E0 E1 d:d=4 dv:dv=4 q:q=5 qv:qv=5
