It is a memory-sharing architecture in which data and programs are stored in the same memory block. In comparison, Harvard architecture is a memory-sharing system in which data and instructions are stored in separate memory blocks.
John Von Neumann, a renowned mathematician and scientist, invented this architecture in 1945. Harvard Architecture is a kind of digital computer architecture that is built on the notion of distinct storage and distinct buses (signal paths) for instruction and data. Von Neumann Architecture, as comparison to Harvard Architecture, needs less architecture. This is because it only needs to connect to a single shared memory. This one requires additional hardware. This is because every memory needs its own set of data and address buses. Space Requirement.
The Harvard architecture is a kind of computer architecture in which instructions and data are stored and routed separately. This is in contrast to the von Neumann architecture, which shares memory and paths between program instructions and data. The phrase started with the Harvard Mark I relay-based computer, which used punched tape to store commands and data and electro-mechanical counters to record data. These early computers had all data storage solely inside the central processor unit and without any external storage. For program and data storage, the Von Neumann (a.k.a. Princeton) architecture built for the ENIAC employs the same memory and data channels. Harvard's design, as shown by the Harvard Mark 1, used physically distinct memory and data pathways for program and memory.
