Von Neumann Architecture and Harvard Architecture | Computer Architecture

[@k283]

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..

Thank you for the comment! 1. I agree with that one. And my next video will cover cache related info! 2. Actually, transistor weren't present at that time. We are talking about the days of vacuum tubes!

​@@ArneChristianRosenfeldtHarvard architecture was invented by IBM, back when Big Blue was cool... They stored their programs on punch cards, writing data back to a punch card wasn't practical.

Amazing lecture. Liked it from Pakistan.

Please add, video about booting process of microcontroller and steps after reset.

[@priyanshudua8330]

quite good video😇,answered alot of questions

[@ViralXo3]

Great exaplanation ,like from zambia Unza 🙏

[@italooliveira5574]

Damn good class, it comes with nostalgic university memmories

[@kayakMike1000]

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.
