I. Assume r0=0xAD10 0002 and r1=0x3FF8 0000, what will be the value of register r2 after executing the following instructions?

MOV r2, #0

CMP r0, r1

BGE ELSE

B DONE

ELSE: MOV r2, #2

DONE:

II. Consider the four addressing modes given below used by ARM7 along with an example of each.

a. Immediate ADD r2, r0, #5

b. Scaled register ADD r2, r0, r1, LSL, #2

c. Scaled register pre-indexed LDR r2, [r0, r1, LSL, #2]!

d. PC-relative BEQ 4000

List benefits and drawbacks of each ARM addressing mode.
