speculable exu stream exu block compute phase operation in the binary floating point value domain using excepting overflow behavior that produces condition codes and rounds use current dynamic rounding mode
Exactly convert a binary floating point value to a unsigned integer, in current rounding mode and producing NaRs on overflow.
operands: like Addf [ff:f]
| Core | In Slots | Latencies |
|---|---|---|
| Silver | E0 E1 | w:w=3 wv:wv=3 d:d=4 dv:dv=4 q:q=5 qv:qv=5 |
| Gold | E0 E1 E2 E3 | w:w=3 wv:wv=3 d:d=4 dv:dv=4 q:q=5 qv:qv=5 |
