If you’ve ever been curious about computers, you might have wondered how they run programs and the steps involved in the process. I know I did. I read bits and pieces of information here and there, but I never quite got the full picture—maybe because I was lazy.
Then one day, I stumbled upon a post trending on Hacker News titled "Putting the “You” in CPU". And this is the one of the best and detailed article (very long one) i've ever read. Authors must have researched for weeks to accomplish this but it's worth it.
As I read through it, I realized it was hard to recall everything, so I used excalidraw to create a visual illustration which helped reinforce my learning. I’m sharing it here mainly for my own reference, and I’m not expecting anyone else to make sense of it.
That said, if you haven’t already read the article, I highly recommend it. It’s a fantastic resource for anyone curious about the inner workings of a CPU.
