Circular shift in verilog
WebIn computer programming, a bitwise rotation, also known as a circular shift, is a bitwise operation that shifts all bits of its operand. Unlike an arithmetic shift, a circular shift … WebQuestion: 1. Develop a Verilog model for a 4-bit barrel shifter, which produces a 4-bit output that performs "Rotate Shift Left" or "Circular Shift Left". The 4-bit input vector shall be named 1 (3:0), the number of bit positions to shift is SH [1:0), and the output is [3:0). Note that a barrel shifter (or rotate/circular shift operation ...

I have to create a 5 bit shift reg , with the following options : 000 : Reset / 001 : Parallel loading / 002 : Right shift / 003 : Left shift / 004 : Circular right shift / 005 : Circular left shift / 006 : 1s' complement / 007 : 2s' complement I have every module , but i can't create the final module , i don't know it's … 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
