realizing  exu stream  exu block  compute phase   operation   in the decimal floating point value domain   that produces condition codes and rounds to nearest, ties toward even adjacent value

native on: Decimal8 Decimal16

Decimal floating point subtraction in current rounding to even.


subde(d x, d y) → d r0

operands: like Addd [dd:d]


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