### Question 13

The flowchart below presents the tasks involved in binary number multiplication through repeated shift operations and additions. Which of the following answers is the correct combination of processes a and b in this flowchart? In this example, multipliers and

multiplicands are expressed as 16 bits without signs. X, Y and Z are 32-bit registers, and logical shifting is used for shifting.

a | b | |

a) | Least significant bit in Y | Shift X one bit to the left and Y one bit to the right. |

b) | Least significant bit in Y | Shift X one bit to the right and Y one bit to the left. |

c) | Most significant bit in Y | Shift X one bit to the left and Y one bit to the right. |

d) | Most significant bit in Y | Shift X one bit to the right and Y one bit to the left. |
