Chapter 6, Problem 20E

a)

Explanation of Solution

Number of bits present in the virtual address:

• The memory system is byte addressable.
• A page contains 8 bits.
• Total number of page=8 pages
• Total number of bits=64 bytes

Represent the bits in the binary format:

8 pages can be represented as 2³...

b)

Explanation of Solution

Number of bits present in the physical address:

• The memory system is byte addressable.
• A page contains 8 bits.
• Total number of page=8 pages
• Total number of bits=64 bytes
• Number of frame=4.

Represent the bits in the binary format:

4 frames can be represented as 2²...

c)

Explanation of Solution

Physical address that corresponds to virtual address:

To represent the physical address that corresponds to the virtual address it is required to convert the given hexadecimal numbers into 9 bits equivalent binary number.

Hexadecimal number	9 bit binary number			MSB (last three)	Decimal equivalent	validation	Physical address
0x00	000	00	0000	000	0	Contained in frame 1	01000000
0x44	001	00	0100
