4. Figure 4.1 is a basic multiplication hardware and Figure 4.2 is an improved
version of the basic one.
Figure 4.1: Basic multiplication hardware
Figure 4.2: Improved multiplication hardware

The following statements are possible observations for the improvement:
S1: The multiplicand register, ALU, Multiplier register and the Product register are all 32 bits wide；
S2: The Product register always shifts right two bits in each iteration；
S3: The original Multiplier register disappears and is now placed in the right half of the Product register initially；
S4: The left side of the Product register is initially set to zero.
S5: The Multiplicand register is initially set to zero.
Please copy the following table (Table 4) to your answer sheet and determine if these statements are true or false.
