realizing exu stream exu block compute phase operation in the decimal floating point value domain that produces condition codes
Decimal floating point subtraction in current rounding to even.
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 |
