Supporting Operations #21
Description
Based on the README, the MAC instruction operands type are as follow:
| Type | Command | Description | Result (DST) | Operand (SRC0) | Operand (SRC1) |
|---|---|---|---|---|---|
| Arithmetic | MAC | multiply-accumulate | GRF_B | GRF, BANK | GRF, BANK, SRF |
The paper mentions that there are 14 combinations for this instruction, but I'm unclear on how this number is derived. Specifically:
- Is the MAC with the auto bit counted as a single combination?
- Can the bank type be used for both operands?
Could you clarify the 14 possible combinations?
