speculable exu stream exu block compute phase operation in the unsigned integer value domain using saturating overflow behavior that produces condition codes
aliases: subus2
native on: all
Saturating unsigned integer subtraction. When a result value overflows for the width, it flats out at the biggest value.
operands: like Identity [xx:x]
| Core | In Slots | Latencies |
|---|---|---|
| Tin | E0 | |
| Copper | E0 | |
| Silver | E0 E1 E2 E3 | |
| Gold | E0 |
