![4.28 LAB: Multiplications and divisions using shift operations -
bitwise operations
Shifting a positive integer left by i bits gives the same result as multiplying the same integer by 2⁰.
Nx 2¹ = N <<i
Likewise, shifting a positive integer right by i bits gives the same result as dividing the same integer by 2¹.
N÷2¹ = N >> i
Given an integer N stored in X19, write a program that stores the result of N x 8 in X20 and the result of N/16 in X21. Use the '+' button
under the Registers display to initialize register value for X19.
Ex: If the value of X19 is initialized in the simulator as 64, the results are stored in X20 and X21:
