In this video we explore the primary processor or the System on a Chip or SoC which is essentially the brain of your smartphone. We'll explore the different sections of the SoC and then see how data moves around. Next, we'll explore what happens when you take a picture, and how the SoC processes this data. Following that, we'll take a look at the CPU section, and finally, we'll see how these SoC are designed and manufactured.

Erratum:
12min 10sec- Enligsh should be English! Ugh such a blunder. Maybe it's a test to see who reads the footnotes. And then another test to see who reads the erratum...

It would be greatly appreciated if you could take a quick second and tell us what you think or provide feedback on the video. Was it too complicated or was a specific section confusing? What about the pace of the video? Was a section too slow or did it move too fast? This feedback is extremely useful and it helps us improve on future videos! So, thank you!

[WarpedYT]

That was amazing and fascinating ! Those illustrations must have taken months to complete.. hope this video goes viral !

[alifox]

This is so detailed. The quality of this video maan... This is unbelievable that these videos are completely free, and how underrated the channel is.

[stefanbuscaylet]

As a computer engineer involved in both SOC and FW implementation for over 3 decades, I am still blown away when you look holistically at what is built. And this only covers the Edge device let alone the communication bits, the flash memory (other videos discussing that amazing technology), the cellular network, data network including undersea cables, the hyperscaler data centers. It really is beyond a single person’s comprehension. Well maybe except for you. Thank you for sharing not only your awesome research, but your graphics and data visualization and story telling skills. You truly are a gift to our world. Thank you so much!!

[dekev]

As a microelectronics Engineering graduate student, I really appreciate how simple and concise this video is, despite the fact that it explains YEARS worth of advanced Engineering classes.

[victorultimate]

a whole semester's long lectures on "Micro Processors" compressed in 25minutes. plus its even more detailed. words cant thank you enough for this great knowledge.

[kanishkkaushik]

THIS is how ALL education should be!!! Incredible accurate detail = SUPREME CLARITY

[kfpfk]

I find your videos fascinating. I'm a long-retired old-school computer engineer, that maintained large mainframe systems which were implemented with transistor gates and logic. These SOC designs remind me of a room full of computer modules wired together with coax cables that I used to maintain. The amount of miniaturization and lowering of costs is staggering. I am proud to have been a part of it and to see where engineering and manufacturing have gone. To you young engineers, keep it going as we're still nowhere near our human potential.

[shidqi]

Yo why this channel is so underrated it
The depth every single video he makes is astounding and it was made beautifully

[sohamlakhote]

Oh my god!!! Even as a PHD student in the field of IC design, this video just blew my mind!! You just bridged a huge gap between how these ICs work together to produce an image or perform different tasks!!!

Kudos to you man!! Seriously hats off !!

[DrFarisArab]

This is next level info graphics..salute. The middle section was fast as complexity increases u should slow down

[loganholdaway]

I'm not sure which is more magical, to know or not to know. No going back though! In all seriousness, these videos are the apex of audio visual communication and education. Thank you.

[davekozg]

Honestly can't image the efforts one had to put in to make such a detailed video. Kudos!

[dhanikaweerasekera]

Man I'm lost for words here. I can't imagine how time consuming it must be to churn out one of these exceptionally well done videos. I'm just really sad that the general population is not interested in this kind of thing for you to go viral. You deserve every bit of support to keep this going. I'm way more thankful and appreciative of the tech around me after your videos. I honestly can't fathom how human kind has become so advanced

[DaveSimkus]

That size-comparison to a grain of table salt is mind blowing. It puts things in perspective.

[pabansaha]

This is something on extraordinary level...Being an chip design engineer I am really shocked to see the accurate detailing of your content. Hats of to you sir...

[aim-iitdelhi]

The only YouTube channel that provides the fundamental knowledge of electronics.
Keep it up👍

[victorboechat]

I can't understand why there's no millions of people subscribed to this channel. This is superb!!! I've watched all your videos!

[kitni]

I cant believe im watching this for free

[ldchappell]

I'll certainly treat my smartphone with reverence after seeing this. I had *no idea* there was so much going on inside my cellphone. It's the kind of thing you don't think about unless something's not working properly.
Whoever put this video together did an excellent job. It was instructional without being overly technical.
It's amazing how fast these computer achievements happened. Only 24 years after the invention of the transistor, Intel introduced the 4-bit 4004 with 2, 300 random logic transistors. Now we're using 64-bit multi-core processors with billions of transistors.
I'm 65 now and when I was younger I thought the quick rate of our technical advancements was a great thing, but as I got older I started realizing that maybe we're not ready for some of these advancements.
