Which of the following best encapsulates the fundamental difference between the von Neumann and Harvard architectures in computer systems?
- 1The Harvard architecture employs a more complex control unit compared to the von Neumann architecture.
- 2The von Neumann architecture is primarily used in modern microcontrollers, while the Harvard architecture is prevalent in general-purpose computers.
- 3The von Neumann architecture utilises separate address spaces for instructions and data, while the Harvard architecture uses a single address space.
- 4The Harvard architecture allows simultaneous fetching of instructions and data, potentially improving performance, while the von Neumann architecture typically fetches them sequentially from the same memory space.✓
Correct answer
The Harvard architecture allows simultaneous fetching of instructions and data, potentially improving performance, while the von Neumann architecture typically fetches them sequentially from the same memory space.
