speculable  exu stream  exu block  compute phase   operation  

native on: all

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 1
Copper E0 E1 1
Silver E0 E1 E2 E3 1
Gold E0 E1 1

exuArgs(op arg0, op arg1)

operands: like Inv :


Core In Slots Latencies
Tin E0 E1 1
Copper E0 E1 1
Silver E0 E1 E2 E3 1
Gold E0 E1 1
