Показать описание
In this video, I have explained the Von Neumann Architecture and Harvard Architecture.
I have covered the blocks or units of both the architectures and included an explanation of the Instruction Cycle (Fetch-Decode-Execute) as well.
You'll also be able to understand the stored program computer concept.
Each architecture comes with its own set of advantages and limitations which are explained in depth.
You will come to know about the applications/uses of both architectures.
In the end, there are two questions, check if you can answer them!

Cheers!

1. Since instruction pipelining may require simultaneous access to both data memory and instructions memory, it is hard for pure von Neumann architecture to achieve that.. But if you cache the instructions and data (thus creating a small "ROM" and "RAM", respectively), then it can be done with von Neumann architecture, though this will be closer to Harvard..
2. Simple branching and loops should be possible to build with just hardware, transistors. For example, we can implement branching using multiplexer - demultiplexer gates, which physically activates or deactivates different parts of the chip, thus altering the output of the chip; that can be branching... Or take a simple counter, that counts from 0 to 9 and back to 0 with intervals of 1 seconds - it can be the example of loops. No program needed, not even fixed one; a certain way of wiring the hardware parts together in this case is the program itself..

Von Neumann architecture was an interesting insight that instructions were just data. The Harvard architecture was invented because IBM just wanted to use punch cards for ROM.
