Question

Explain what each of the following does: a. mov eax, ebx b. mov eax, 0 times 42 c. mov eax, [0 times 4037C4] d. mov eax, [ebx] e. mov eax, [ebx + esi * 4] Assume that registers EAX and EBX contains the values in Figure 1 and memory values at the given addresses are as shown. a. Explain what the command mov eax, [ebx + C] does. b. Explain what the command lea eax, [ebx + C] does. Assume registers EAX and EBX are as they are in 2 and EDX and ECX are 0 times 00A30040 and 0 times 00000001. State which register each respective result gets stored and the value. a. sub eax, 0 times 10 b. add eax, ebx c. inc edx
