Aug 4, 2021 · Harvard Architecture is the digital computer architecture whose design is based on the concept where there are separate storage and separate buses (signal path) for instruction and data. It was basically developed to overcome the bottleneck of Von Neumann Architecture.
Mar 26, 2024 · Von Neumann architecture is the foundation for most modern computers, while Harvard architecture offers an alternative design for specific applications. This article provides a detailed comparison of the two most popular computer architectures. Hossein Ashtari Technical Writer. March 26, 2024.

- Difference Between Von Neumann and Harvard Architecture
It is a type of digital computer architecture in which the design follows the concept of the computers with stored programs where they store the program data along with the instruction data in the very same memory. The famous physicist and mathematician John Von Neumann designed this architecture back in 1945.
It is a type of digital computer architecture in which the design follows a basic concept of having separate signal paths (buses) and separate storage for data and instructions. This type of architecture basically surfaced to overcome the overall bottleneck of the Von Neumann Architecture.

Both types of architectures contain the same components, however, the main difference is that in a Harvard architecture the instruction fetches and data transfers can be performed at the same time (simultaneously) (as the system has two buses, one for data transfers and one for instruction fetches).
Jul 29, 2022 · In contrast to the Von Neumann design, which retrieves instructions from memory using a single bus while simultaneously moving data from one component of a computer to another, the Harvard architecture keeps data and instructions in their own distinct memory spaces.
The key factor of differentiation between Von Neumann and Harvard architecture is that in Von Neumann architecture a single memory containing both data and instructions is accessed by the CPU. On the contrary, in Harvard architecture, individual memory units are present for data and instructions that are accessed by the processor.
