Question

4. In a microcomputer the address of memory locations are binary numbers that identify each memory circuit where a byte is stored. The number of bits that make up an address will depend on how many memory locations there are. Since the number of bits can be very large, the addresses are often specified in hex instead of binary. a. If a microcomputer uses a 16-bit address, how many different locations are there? b. What is the hex address of the 256th memory location? 5. Perform each of the following conversions: (123)s( BCD b (625): = ( e (ABCDEF)16

Explanation / Answer

4.

a-> If a microcomputer uses a 16-bit address 2^16 different location will be there.

b-> 256th memory location : 0x100

5.

a-> 123 conver in to decimal

1*8^2 + 2*8^1 + 3*8^0

83

->10000011

b->625 convert in to decimal

6*7^2 + 2*7^1 + 5*7^0

313

->now onver into base 5 means devision method.

5 313 3

5 62 2

5 12 2

5 2 0

so, ans - 0223

c-> ABCDEF -> 101 010 111 100 110 111 101 111

-> ans - 52746757
