Expert Solution & Answer
Chapter 2, Problem 7RQ
Explanation of Solution
Difference between tag-based addressing and rack/slot-based addressing:
Tag-based addressing | Rack/Slot-based addressing |
In tag-based addressing, a tag is used to address data. | In slot-based addressing, a fixed numerical format is used to address data. |
Here, it defines the memory location where the data is stored... |

1- Direct Addressing
A common bus in a computer connects 16 source registers (each register is 32 bits) and one memory unit with word size of 32 bits also.
If the bus is designed using multiplexers, answer the following:
• What is the minimum number of multiplexers required?
What is the minimum number of select lines each multiplexer has?
If the bus is designed with three-state buffers and decoders, answer the following:
• What is the minimum number of three-state buffers required?
• What is the minimum number of decoders required?
• What is the minimum size of each decode
When it comes to the Von Neumann architecture, does the external bus just carry data memory?
