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.
