John von Neumann is one of the founding fathers of computing and a major 20th century mathematician. Questions under this tag generally relate to what is now known as the 'von Neumann architecture' for stored-program computers.

The Von Neuman Architecture describes a computer with a single control unit that sequentially works through instructions. Instructions and data are stored in memory together, both of which are sent along the same bus.

How do contemporary processors differ from a pure von Neumann architecture?

So I never really understood the von Neumann architecture, and have started to revise it as I wasn't in school during the lessons of the CPU. Can't really get help through my teacher as they wont respond to their email. I have learnt about the von…

Which architectures are Harvard and which are Von Neumann?

I was trying to figure out which of the following architectures can be classified as Harvard (either 'strict Harvard' or modified Harvard, as long as instructions cannot be fetched from data memory, the other way around is fine) and which as Von…

Does von Neumann say anything about which way data flows?

I stumbled upon this quote while reading about React (emphasis mine) In React, data flows one way: from owner to child. This is because data only flows one direction in the Von Neumann model of computing. React Docs: Two-Way Binding Helpers It…

Finding the position of the lowest value in a Von Neumann Neighborhood

I have a 2 dimensonal array in Javascript with floats inside. I have to iterate over every item in the array and find the position of the lowest float in a Von Neumann Neighborhood. The problem is I know how I find the lowest value, but not how to…

Harvard Architecture maps to HLL

This is a question I have been searching for a while but I have not got a proper answer yet :( How does the Harvard Architecture map to C/C++ languages (High Level Languages)? How are they related or how does the architecture help HLLs?

Simple truly random number generator

There is a lot of research going on related to generating "truly" random numbers. There is a very simple method, invented long time ago. The method is attributed to von Neumann [1]. In the most simple form it can be thought of as generating random…

Why is von neumann faster than harvard architecture

I read about these two types of architecture and somewhere on the internet someone said that systems using Von Neumann architecture are faster than the ones using Harvard architecture. I tried searching for why this is the case but I was yet to find…

why do we use RAM model of computation for algorithmic analysis when it corresponds to harvard architecture?

As per Wikipedia , RASP model of computation corresponds to von Neumann Architecture while RAM model of computation corresponds to Harvard Architecture and von Neumann architecture is closest to computers since we have ram memory in our computers…
