Hello everyone, yeah its been one week since my last post, as expected. Interview So today’s question is How are we able to run multiple apps at once in our computer? You may say, just open whatever you want and be done with it. That’s true, but how?. Let me expand the question, suppose we are in early 2000s, you just got your single core Pentium 4 computer with windows XP on it.

What is a Program and How does it run on CPU? Program is a mix of code and data that makes the CPU do what we want, aka super powers. Sadly CPU only speaks Zeros and Ones that what all people say 🤷‍♂️, but the real language that we can talk to CPU still being able to keep our sanity is Instruction Set. Ahh, sorry for the deviation. So yeah zeros and ones.

what is going on?

As being a nerd about open source and CPU architecture, I’ve decided to learn more about riscv ISA (Instruction Set Architecture) and try out making a core with it. In past I made my own 8bit ISA and implemented it on FPGA, but it feel now is time to try out bigger 32bits turf and try adding some AI Accelerators as the finishing touch. I have basic knowledge of how CPU works and how to write Verilog, But I feel like I don’t have enough experience in it. I just made a non pipelined CPU before, so this time plan of attack will be different.

My Intro Hi, I am Mohd Fahad. I am currently studying final year of BE in ECE. I am quite interested in working of a computer form sand to software and a big anime fan, you can name an ainme probably i’ve watched it or know about it 😎 . Here I will blog about my daily adventures, new things i learned and things that makes least sense to do 😇 .
