The Branch Education YouTube channel takes a look at the mechanisms at work within a CPU, so that this all-important chip no longer holds any secrets for you.
There's no need to hide it: just because we talk a lot about processors and all dream of having the most powerful Ryzen 9 in our PCs, doesn't mean we know exactly how things work inside these silicon concentrates, which today can integrate a whopping 16 billion transistors to carry out over 3 trillion calculations per second (figures from Apple's M1 chip).
In the video above, Branch Education's specialists take the time to describe how it all works. They decipher the five-step cycle of Fetch - Decode - Execute - Memory - Writeback, and proceed in very didactic steps, using analogies that are as simple as they are meaningful, to make things clear. Obviously, given the name of the channel, the video is in English and lasts just over 35 minutes, but frankly, it's worth your time unless, of course, you're already familiar with all this. What's more, even if the result isn't perfect, the automatic translation of the English subtitles should be able to help out the less English-speaking among you. Enjoy your viewing.
