Processor Architectures

What is the main difference between the von Neumann and Harvard architectures?

• In von Neumann architecture, instructions and data are stored in the same memory space, while in Harvard architecture, they are stored in separate memory units.

• In von Neumann architecture, instructions and data are stored in separate memory units, while in Harvard architecture, they are stored in the same memory space.
