Fun Fact ! - The Harvard Mark I from 1944 used a 3.5 hp electric motor running at a constant speed to act as the computer's "clock" and could mange up to 3 (THREE !) additions or subtractions a second. A single multiplication took around 6 seconds, a division 15 seconds and a log or trig function around about a minutes.

The miracle of the age !

Talk about perfect timing. We were going over ALUs and registers in one of my classes just last week.

i think an interesting video would be how a core is different than a thread, any why some CPUs support 2 threads per core and other CPUs do not.

“Fast enough to help you watch this video”

*Wise words*

I'm reminded of the time when we had to build a rudementary 8-bit ALU out of individual DIP type IC's of logic gates and memory. Needing to wire up power, clock signal and 8 data wires between each IC. Good times.

This should be expanded upon in very technical details... we need a hour+ long CPU core video on LTT (or series of shorter vids)

"more cores more better"
-linus a long time ago

There are different implementations of CPUs. The accumulator type is typical with x86 (Intel and AMD) CPUs. Other implentations store data on RAM entirely without the need of an accumulator or registers, others like MIPS (old game consoles and other computers) primarily use registers only. There's also different implementations of how instructions are read- one instruction at a time keeps things simple but logs up waiting instructions, multicycle allows reuse of parts of the CPU for each instruction but in some cases can end up increasing instruction time, and pipelining divides the CPU into sections so that multiple instructions can run on each stage of the CPU, but with added complexity and the need to ensure an instruction isn't waiting on the result of a future instruction still being completed.

I never knew CPUs had a different ALU for Floating Point numbers.
It actually really makes sense, both an Integer and a Float are represented as a 32 bit number, the difference is the mathematical operations on them

I needed this video exactly last year today,

[krischalkhanal]

I was just talking about how CPU does things with my friend, and was searching for resources to explain. This was the perfect timing.

Topic suggestion: how high level code gets converted to CPU instructions. Always fun to see under the hood.

[MasticinaAkicta]

In the early days things were easier, one core running very slowly directly connected through motherboard lines with memory. Cache? What was that!
That aside ;) yeah it is good that we now have IO controllers, memory controllers, TTM's and a whole lot of cache. From L1, L2 and L3. All to make sure your fancy cpu's actually can push out the data as quick as possible. Without cache we still would go very slow indeed.

You should do a video explaining the “bridge mode” on modems and the pros and cons

[chrismast]

Where is the smoke kept? I've accidently let that out before and couldn't figure out where to put it back in.

[ktvx.]

It's funny to me that in computing, "high level" actually means more basic and accessible amount of knowledge or communication with the computer

IPS, VA, and other panel types of displays Tech quickie needs an update

[plumokin]

I work in this industry so I know almost everything in these videos, but I LOVE seeing the simple explanations. It takes a lot of skill to teach complex things. For anyone wanting to learn more, computer architecture is a fantastic course.

[vladislavkaras]

It was pretty interesting to watch. Really informative.
Though, I would say a music was a bit loud, but it keeps you awake ;D
Keep it up!

[abhinavrobinson]

I like the fact that most of these videos are 4:20 in length :`D
