Silicon to Scripting 12
This level is very very similar to the Logic Unit (LU), so try to do it on your own.
Arithmetic Unit
op1 | op0 | output |
|---|---|---|
| 0 | 0 | X + Y |
| 1 | 0 | X - Y |
| 0 | 1 | X + 1 |
| 1 | 1 | X - 1 |
One tip is that you can use a standalone inv to get a constant 1, and you can use the lower-bit values like 0 and 1 in 16 bit operations.
Look closely at the op0 and op1 bits, as they alternate in a different pattern this time.
This requires a slightly different configuration of selects at the top, but the idea is still the same.
