Chapter 7, Problem 16E

Explanation of Solution

To find:

• The number of conductors required if the address bus wishes to be able to address 8 devices.
• The number of conductors required if each device wish to communicate to I/O control device.

Solution:

Number of conductors needed if the address bus able to address 8 devices:

The eight devices may be: 000, 001, 010, 011, 100, 101, 110, and 111.

The address as well as data bus contains various conductors in which each carries one bit of data. The bus’s width can be found by determining the number of data lines. If there are 8 data lines then the bus could transfer 8 bits, that is, 1 byte at a time...
