Suppose memory access takes 100 ns and register access takes 1 ns (or less), calculate and compare the computational speed of the three code snippets. Assume CPU instructions such as XOR, ADD, also take 1 ns and we flush everything in the cache before executing the programs.

Suppose memory access takes 100 ns and register access takes 1 ns (or less), calculate and compare the computational speed of the three code snippets. Assume CPU instructions such as XOR, ADD, also take 1 ns and we flush everything in the cache before executing the programs.
Program snippet 1:
Mov EAX, [0x 8002 B001]
Mov EBX, EAX
XOR EAX, EAX
Program snippet 2:
Mov ECX, 0
Mov EAX, 1
ADD ECX, EAX
Mov [0x 8009 0001], ECX
Mov EAX, [0x 8009 0010]
Program snippet 3:
Mov EAX, Ox 4001 0000
Mov EBX, Ox 4001 0001
ADD EAX, EBX
XOR EBX, EBX
