Assume that the program has been built successfully and proceed with the debugging (F10 step over) process. Consider the initial content of the EAX = 0019FFCC.

Answer the following questions in sequence.

(a) Complete the following Table 1 by writing the content of the main memory starting with the address at 0x00406000. For unused address, write the answer as FF. [4 marks]

Table 1

0x00406000
0x00406004
0x0040600C

(b) Complete the following Table 2 by writing the content of the EAX register at all instructions with the labels of (i) to (iv). Assume that the instructions were executed at each label in sequence. [4 marks]

Table 2

Label	Content of EAX
(i)
(ii)
(iii)
(iv)

(c) If an instruction is inserted at line 27 as shown in the following figure, what will be the new content of the EAX and EBX registers once executed successfully? Assume the initial content of EBX = 003F1000. [2 marks]
