array.s ARRAY: .word 1 1 2 3 5 8 13 21 34 55 (index i) 0 1 2 3 4 5 6 7 8 9 For the i th element ARRAY[i], the address is ARRAY + 4*i
Example: 5 10 = 00101 2 A clever way of multiplying by 2... Multiplying by 2 is equivalent to shift 1 bit to the left. Multiplying by 4 is equivalent to shift 2 bits to the left. 2* 5 10 = 10 10 = 01010 2 Same as 00101
