Pick between two values based on a condition value being a NaR or not.
This works like a pick operation, except that is doesn't look at the lowest bit of the value, but at the NaR Metadata flag.
related operations: pick
operands: like Inv :
| Core | In Slots | Latencies |
|---|---|---|
| Tin | P0 | 1 |
| Copper | P0 | 1 |
| Silver | P0 P1 | 1 |
| Gold | P0 | 1 |
