speculable exu stream exu block compute phase operation in the binary floating point value domain using modulo overflow behavior that produces condition codes and rounds toward negative infinity
Exactly convert a binary floating point value to a signed integer, rounding toward nearest and normal modulo 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 |
