# exuArgs

From Mill Computing Wiki

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.
