WebSep 29, 2024 · What you want to do is to shift right by 5 bits (8-3=5): (8 - bits_to_rotate). This will shift all 8 bits to the right by 5 positions, dropping the 5 LSB's and adding 5 0 bits to the MSB's. This gives you 8'b0000_0011. Then, when you do the bitwise OR of the 2 terms, you get: 8'b0001_0000 8'b0000_0011 = 8'b0001_0011. Change: WebNov 12, 2013 · This is known as a logical shift, since it strictly follows the logical definition of "shifting", that is, moving the existing bits one position towards the LSb. If we shift in the same value as the MSb, we change the value but retain the sign: 0b0110 (6) -> 0b0011 (3) 0b1110 (-2) -> 0b1111 (-1)
