Harvard architecture

Unlike the Von-Neumann architecture, the Harvard architecture is a stored program architecture where the instructions and data are stored in separate memory regions.

This means that the CPU has two separate memory address spaces: one for instructions and one for data.

The Harvard architecture is a stored program architecture where the instructions and data are stored in separate memory regions to each other.

Where is Harvard used?

• It’s mainly used in embedded systems, for example, in digital signal processing (DSP).
• It’s not common to use it for a general-purpose computer.
