Table XCver-2 on the next page is an excerpt from a behavioral Verilog program for a 16-bit barrel shifter that performs any of six different combinations of shift type and direc-tion. 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. Regards Mitu Raj Forum Access 17 posts
