Additional arguments for Ganged operations.
All data paths for the operands of compute operations are optimized for 2 operands. Yet some operations need more. For those operations, like fmaf or inject, a primary opcode in one Slot and the `exuArgs` opcode in the next together form the full operation with all operands.
This is possible because neighboring Slots and their Pipelines can pass data between each other in a side path without needing a full interconnecting data path.
exuArgs(op arg)
operands: like Inv :
| Core | In Slots | Latencies |
|---|---|---|
| Tin | E0 E1 | 0 |
| Copper | E0 E1 | 0 |
| Silver | E0 E1 E2 E3 | 0 |
| Gold | E0 E1 E2 E3 E4 E5 E6 E7 | 0 |
| Decimal8 | E0 E1 E2 E3 | 0 |
| Decimal16 | E0 E1 E2 E3 | 0 |
