1Types of CPU Architecture?There are two main types:
Von Neumann
Harvard Architecture
2What is "Von Neumann Architecture"?Von Neumann architecture involves a single memory storage followed by a processor.
3Pros and Cons of Von Neumann?Cons:
-The instructions and data are stored in the same format.
- Follows a linear fetch-decode-execute cycle
- Cannot use pipelining
Pros:
- Seperate buses are not required
- "Flexibility": Data space can be used for instructions, therefore no maximum ratio of division.
4What is "Harvard Architecture"?Harvard Architecture involves 2 separate storage locations for instructions and data and includes the processor.
5Pros and Cons of Harvard ArchitecturePros:
- Can support pipelining
- No complications and mix-ups between instruction and data
Cons
- Data and Instruction have a max capacity that may not be able to be expanded.
