Please be clear in your answer

Show the main memory address range of a CPU with a 24-bit address bus. (Show the smallest and largest address values in hexadecimal) Show the main memory address range of a CPU with a 36-bit address bus. (Show the smallest and largest address values in hexadecimal) Show the main memory address range of a CPU with a 64-bit address bus. (Show the smallest and largest address values in hexadecimal)

Solution

Ans) If \'n\' is the no fo bits in address bus ,then memory range is 0 to 2ⁿ-1 total of 2ⁿ locations in decimal

a)24 bit ----address range is 000000 to FFFFFF Hexadecimal every 4 bits in hex is F for 24 bits total 6 F\'s

b)36 bit ----address range is 000000000 to FFFFFFFFF (Total 9 F\'s as 9*4=36 bits)

c)64 bit ----address range is 0000000000000000 to FFFFFFFFFFFFFFFF (Total 16 F\'s as 16*4=64)
