WebFor the fourth row, a 3-byte circular left shift is performed. The following is an example of ShiftRows. The inverse shift row transformation, called InvShiftRows, performs the circu- lar shifts in the opposite direction for each of the last three rows, with a 1-byte circular right shift for the second row, and so on. 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.
