The number 1, 234, 567 is stored as a 32-bit word starting at address 16. Show the address and contents of each byte of the 32-bit word on a (a) little-endian system, (b) big-endian system.

Solution

The number is 1,234,567 .Converting it into decimal we get, (1234567)₁₀ = (12D687)_16.
As we know in Hexa decimal notation each digit represents 4 bits.

32 bit word starting address is F043900₁₆

a)LITTLE ENDIAN SYSTEM :

F043900₁₆=87

F043901₁₆=D6

F043902₁₆=12

F043903₁₆=00

b)BIG ENDIAN SYSTEM :

F043900₁₆=00

F043901₁₆=12

F043902₁₆=D6

F043903₁₆=87
