WebJul 15, 2024 · 1) The first statement does sign-extending to 6 bits first, and then shifting- eg: 0101 (+5) --> 000101 --> 001010 (+10) eg: 1010 (-6) --> 111010 --> 110100 (-12) I do not think so how do you know the final sign if you do not perform the operation first. I believe the extension happens after.
