WebSep 29, 2024 · For any value of bits_to_rotate from 0 to 7, ~bits_to_rotate will always be larger than 8. 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. WebThe RCR (rotate carry right) instruction shifts each bit to the right, copies the Carry flag into the MSB, and copies the LSB into the Carry flag.
