It’s freaking me out that this channel went from a typical “host sitting at a computer in the corner of a screen cast” to a full on television show. In like a month! And the content is new and engaging, not just someone reading a Wikipedia page at the audience. I was already subscribed but well done. Looking forward to the next one.

I am a digital designer and been diving pretty deep into RISC V in the last year or so, and no joke that is one of the best pieces of work I've seen. Amazing explanation while still beeing entretaining, keep the great work, you've just gained a new fan
I have seen every kind of video on TH-cam, but nothing prepared me for this. This is my first video of LaurieWired. I didn't expect to go from analogies of baking sheets to coding vectors in raw risc-v assembly using Mac OS 9 Windowing system, the modern Windows Terminal with a Win XP start bar. I was on the edge of my seat watching you hold that cookie and never taking a bite. You're a menace and I am here for it.
Tech + attractive girl + amazing information presentation + old school MacOS window system. These videos are amazing and ive been binging. Going to use these to teach my kids too.
As an ex VLSI engineer this was an amazing quality intrduction to vector processing, but also video production, meme's and audio all are great. Susbcribed for more!
this juxtaposition of nitty-gritty details and the airy and pleasant presentation style is the format i never realised i wanted, but it just works, keep it up :)
Laurie, you are an excellent speaker! Never once said, "you know" or "just". Not a single word whisker. You are the Standard all should strive to meet. Thank you! I have subscribed.
Im really proud that RISC-V is finally getting noticed. Actually, I'm working as intern in order do develop verilog modules for such operations in RISC-V Architecture.
I have never felt more engaged watching a TH-cam video on any topic like this in maybe forever, I am losing my mind right now. I have never wanted to work with RISC architecture as much as I do now. I don’t think I’ve ever subscribed to a channel so fast
Amazing flow of explanation and balance between technical details and real world analogies to help the viewer understand. Production quality and editing are very impressive. I learned a lot and your obvious passion for this topic is inspiring.
Gosh, I was really totally following the first 8 minutes of this video. The history lesson was so interesting. You're a natural teacher. Love all of the new editing stuff too. My new favorite words, VECTOR VECTOR!
great video, I thought a lot of it would go over my head but you dumbed it down then built up the complexity in such a way that I followed the whole way through
1. The actual content of your videos are sophisticated and intelligent 2. Please do a BTS video showing how you do the things you do, this has got to be easily the best set design I ever seen in a channel. You are definitely a multi-talented genius thank you so much for sharing your work!
@LaurieWired, this is my first viewing of your channel. I've learned some things, have a new SBC to order, and feel like I just received an invite to Cyberia. I'm glad that you exist. Thanks!
I work at Tenstorrent, where we, among other things, design RISC-V CPUs primarily for data center use. It's good to see RISC-V gaining popularity and support. Hopefully, the ARM-x86 duopoly will come to an end!
Your aesthetic, enthusiasm, and vibes are amazing! The attention to detail and passion you put into your videos always leave me impressed. The cut at 29 seconds had me cracking up. I really appreciate the pauses you include between pieces of information; it gives me time to process everything. All the different bits really take this from good to great. This video even got me hyped up about a new instruction set! I appreciate the disclaimer at the end, too.
Yes, very interesting stuff, and a very interesting time to be watching all this happen. Thanks, Laurie, for making this *exceedingly esoteric* subject both accessible and interesting. You make it look effortless. Do please keep up the good work.
Holy moly. The quality of this video is incredible. I enjoy programming in C++ (hobyist) but never touched asm nor programmed on rasberry pie - I feel inspired to try on these cool new RISC-V systems :)
Wow Laurie, that was intense! A lot of info in this one. Got to read on how do length agnostic intructions work. Interesting musical quotes from Madonna's Ray of light album around 4:00 - hard to believe this album came out the same year as SSE instructions did :)
You can actually do VLA in software on Intel / arm based CPUs using clang’s C vector language extensions. You can declare a vector with 64 floats in it, for example, and the compiler will split it up into the appropriate vector size depending on whether you have 16-, 32- or 64-byte vectors, all of which are common on different Intel CPUs, depending on the vector extension flag passed to the compiler. If you are tired of rewriting software for N different vector lengths, it is the way to go. The compilers ability to narrow vectors is flawless.
What a fantastic channel. Great writing, great editing, and wonderfully technical and educational content. The video style and spoken cadence are strangely hypnotizing and feverishly ethereal. Incredible stuff
Great video and presentation. This reminds me of the robust nature of the TI 99/4 from the early 80s. Need a 16 bit reg? Make one. Run out of registers? Create a new set! We were doing stuff that the Z80 and 6502 couldn't dream of. It looks like you're witness to (and participant in) a new revolution in computing. Hopefully, it goes better than it did for the 99/4 ...
Great video. I'll start a PhD in computer architecture in september so as you say it's nice to have an "open" ISA to work with. People from europe complains about not hearing opinion outside Berkeley, Berkeley made decisions without taking into account out-of-order designs making it more complex. But overall it's nice to have an open ISA and computer architecture investigation switching to RISC-V to have more freedom. Very good video to introduce vector operations I will recommend it to bachelor students :)

Math, coding, engineering is a great exercise for attention. I had a hard time following the usually 90min long modules at university. Now i easily spend 4h on a problem if my job allows me to do so. I hope that doesn't sound discouraging... It's my job so i prepared around 10 years to do so if we add my time at universities.
@@Michael_Jackson187 Aww, found the fragile guy in the comments who can't stand that there are so many women in the world who are way smarter than he is. It's okay bud. 😢
I really love how passionate you are about the topics you present and also about how you present them. Please, continue to brighten our mood and infect us with your profound and optimistic way of valueing hardware and software
It's literally serial experiments lain but she grew up and became a youtuber haha, I'm loving this. Starting off a little strong with the first video I'm watching being about RISC-V assembly 😳 I'll understand it eventually
Perfect timing with me just finishing a saxpy and dgemv implementation for my post-grad arch class. The permutations of different vector instructions is pretty insane. There's an instruction for everything
I think a different title would be more appropriate for the video. It may be just me but I started the video expecting to learn what is special about RISC-V's implementation of vector instructions (vector length agnosticism) and that is only ⅒ of the video. And during the assembly section, the most important line for vector length agnosticism (vsetvli) is glossed over. The assembly sample also does not make use of t0, which is pretty crucial to understand what makes RISC-V's vector ISA special. Furthermore, if I understand the docs correctly, the explanation of vector length agnosticism in the video is not really correct. The CPUs do not have flexibly sized vector registers. Rather, they have a way for the processor to pass to the program the number of elements that would fit into its register so that the program can accordingly update the pointer to point at the next region of memory to be processed. This is a cleaner and more general solution to vectors-of-different-sizes problem, but it is important to note that on x86, programs can still read the CPU capabilities at runtime and run different implementations of the same functions for different vector units accordingly. I think for RISC-V the greater advantage of its approach is not backwards or forwards compatibility, it is that the approach allows different processors that are contemporary but on different market segments (and hence have different silicon budgets for vector registers) to run the same code. Lastly, backwards compatibility is not a big deal for x86 vector instructions. For example, 128-bit vector registers are aliases to the lower halves of the 256-bit registers. Sure, there is wasted potential if the program only supports the smaller-sized vectors, but that is not the inefficiency the analogy in the video would imply. The CPU is not keeping "old trays" around, it can cook just 2 cookies in a 16-cookie tray, if that is what is provided by the baker. For the case of the program expecting 512-bit registers but the CPU only having 256-bit registers, there are solutions to that too. Zen 4's implementation of AVX-512 uses 256 bit instructions under the hood. The CPU needs to be explicitly designed to have compatibility with larger vectors, but it is beneficial for supporting programs compiled for larger processors with smaller silicon area.
I absolutely love the production quality on this! I am blown away by how good it is and how well you're able to teach these concepts! I hope more like this can continue cause I love watching it and im sure so many others do! This gives off the vibes that once im done watching this video, I'm gunna go ask my mom if I could have a few quarters to head over to the arcade with my friends, and I love that so much. It feels like im stepping back in time! (Which I appreciate a lot as I was born in the 2000s so I never really got to experience that!)
I love that RISC-V is taking off, having drooled over MIPS and Power-PC decades ago. I love the quality of these videos and the fact she can manage 30 seconds of narration without jump cuts, saying "like" or "awesome". Most of all, the bottle of Glenlivet on the kitchen shelf seals the subscription from me.
16:12 actually for such old farts as i am i could say that we're having opportunity to re-live 70s/80s. Things IT-wise were much straightforward to the point where single person (and i am looking at you Woz) was able to deliver hardware AND software creating complete product. Now times had changed a bit, hardware long time ago passed beyong single person's understanding, but with RISC-V we can at least follow and be up to date with new ISA's additions and HW being released.
@@MrTweetyhack lol, it seems like you don't understand how much technology has advanced in the past years, and how rapidly. If you think that tech in the 70s was as complex as new tech you are dead wrong
@@MrTweetyhackConsidering our infrastructure has to handle Gb being thrown around, through different components and across long distance, in seconds, compared to one device that move Kbs over many seconds, on the same system.... I think computers have gotten more complex than the days of the Apple 1, or Pet.
@@MrTweetyhack this isn't a matter of "understanding" on the level to being able to use it. You can be decent car driver without knowing a single thing about internal combustion engines or how gearwheel sizes affect transmission of torque and speed. But every non-standard usage or modification of said car requires you to have at least basic understanding of inner workings in order to know where to hook and what to change to achieve expected result. Without deep understanding of a car you'll be as good driver as manufacturer allows you to be. For some of us this simply isn't enough.
Having coded ARM32 as a hobby since the 90s (because Acorn Risc Machine!), and having heard of RISC-V for a good while, I will finally look to get one of these new SBCs. Aarch64 lost a lot of the ‘magic’ of Aarch32, and looking at the RISC-V ISA, it looks interesting. Thank you for a great video!
First time here. I think TH-cam brought me here bc I just finished up the show "Devs" and have been watching videos on quantum computers. Vector processing seems like another example of how the future of computing isn't here for consumer electronics (yet) but possibly better suited to help in the large calculations needed to help expand knowledge of physics, nature, etc. Seems like vector processing might be a really good match for interacting/interfacing with quantum computers. Also also, I had a micro controllers professor that said programming in C is like driving and automatic, while programming in assembly is like driving a stick shift. Might not be the best analogy, but your statement at the end made me think of that. Compilers don't always know best, especially since the instruction set is so new.
Intel cpus had vector instructions since a long time. Developers just need to know how to use them or compilers should optimize code that uses those instructions instead of what programmer wrote, recent c# compiler dose that.
Please don't take this first statement the wrong way : I chuckled for a moment hearing your "little girl-like" voice. As the outward expression of a highly intelligent and creative person, it is such a joy for an old, retired coder to hear and witness someone present things in a few minutes that many of us took years to understand. You have a long and very fruitful career ahead of you! Best wishes and looking forward to seeing your next presentation.
Very nice serial experiment Laurie :D the code is similar to assembly, the structure of how the risc-v processor processes reminds me of gpu compute "hlsl\cg". the scalability could potentially be awesome. I'm looking forward to the future of open processing. Excellent content, thank you :)
Thanks to THIS delivery, I'm now totally interested and invested in RISC-V, this is exactly what I want if I go SBC wise.. I love to fiddle with hardware and software since I had my Sinclair ZX Spectrum ( Yes, I'm that old!) and was following along through the SBC scene in search of that special something. Thank you for clarifying RISC-V Vector Specification to me. Disassembler-Editors and Machine code Compilers,your daddy is back.. 🙂
Back in Uni - well before the new millennium - we had this concept of singly, doubly and triply hot women: physically appealing, mentally capable and/or a friendly/helpful heart. Of this set of {pretty, clever, nice} most women have up to two traits - pretty+clever has no need to be nice, pretty+nice is rarely clever, nice+clever is rarely pretty. Having all three of these traits was considered very rare, especially among students of machine-assisted maths (which was renamed computer science later). Having all three traits AND being a fellow nerd was so rare that even just briefly meeting such a quadruply hot woman was worth remembering for life, a cherished memory on the same level as, say, having talked to Brian Kernighan in person. I know this isn't in person and therefore only counts half at best, yet still I am so grateful to have found this channel. Can't wait to watch everything released so far and everything yet to come.
Just took a graduate course in advanced computer architecture.... this vid is spot on! nice work. This would be a cool little board for CS majors to experiment with to get a grasp on RISC-V
I love the fact that the whole style of the videos have changed, BUT still keeps in line with what we know from you with the Laurie Wired windows in the corner and all of that. A mix of old and new 🔥
I’ve never seen someone so succinctly drop a SIMD explainer in my life. Subbed, the production quality and information density alone makes this a winner
Amazing video! Your skillset is incredible. From programming, filming, editing to presenting. I just found this channel through a short and I immidiately subscribed. Love the aesthetics.
Thank you so much for this video and for your work in general! This video is amazingly edited and you make this topic interesting and easy to understand. And ofc I'm glad that you encourage people to learn low-level computer programming
How long have you been in the industry? I get the sense that the only way you could be detached enough from your work to humanize your content would be if you had at least 15 years of experience.

For the case of the program expecting 512-bit registers but the CPU only having 256-bit registers, there are solutions to that too. Zen 4's implementation of AVX-512 uses 256 bit instructions under the hood. The CPU needs to be explicitly designed to have compatibility with larger vectors, but it is beneficial for supporting programs compiled for larger processors with smaller silicon area.
I subscribed the moment I saw the serial experiment lain themed intro. The res of the video was awesome too!
youtube should recommend more videos like this, great content.
I absolutely love the production quality on this! I am blown away by how good it is and how well you're able to teach these concepts! I hope more like this can continue cause I love watching it and im sure so many others do!
This gives off the vibes that once im done watching this video, I'm gunna go ask my mom if I could have a few quarters to head over to the arcade with my friends, and I love that so much. It feels like im stepping back in time! (Which I appreciate a lot as I was born in the 2000s so I never really got to experience that!)
that's the highest pitched technical talk I have ever heard
I thought it was a child at first 😅😂😂
You can thank YT pitch correction for that ;)
I love that RISC-V is taking off, having drooled over MIPS and Power-PC decades ago. I love the quality of these videos and the fact she can manage 30 seconds of narration without jump cuts, saying "like" or "awesome". Most of all, the bottle of Glenlivet on the kitchen shelf seals the subscription from me.
16:12 actually for such old farts as i am i could say that we're having opportunity to re-live 70s/80s. Things IT-wise were much straightforward to the point where single person (and i am looking at you Woz) was able to deliver hardware AND software creating complete product. Now times had changed a bit, hardware long time ago passed beyong single person's understanding, but with RISC-V we can at least follow and be up to date with new ISA's additions and HW being released.
blah blah blah. single people can do much more than ever. just because you don't understand new tech doesn't mean it is difficult
@@MrTweetyhack lol, it seems like you don't understand how much technology has advanced in the past years, and how rapidly. If you think that tech in the 70s was as complex as new tech you are dead wrong
@@MrTweetyhackConsidering our infrastructure has to handle Gb being thrown around, through different components and across long distance, in seconds, compared to one device that move Kbs over many seconds, on the same system.... I think computers have gotten more complex than the days of the Apple 1, or Pet.
@@MrTweetyhack this isn't a matter of "understanding" on the level to being able to use it. You can be decent car driver without knowing a single thing about internal combustion engines or how gearwheel sizes affect transmission of torque and speed. But every non-standard usage or modification of said car requires you to have at least basic understanding of inner workings in order to know where to hook and what to change to achieve expected result.
Without deep understanding of a car you'll be as good driver as manufacturer allows you to be. For some of us this simply isn't enough.
dont forget templeOS dev
he singlehandedly make an entire OS and Programing Language himself albeit with some weirdness
The increased production quality is appreciated. Valuable info as well! ~
1:31 "Huh, that really looks like Seattle."
1:43 "Oh."
Is that a needle?!
Having coded ARM32 as a hobby since the 90s (because Acorn Risc Machine!), and having heard of RISC-V for a good while, I will finally look to get one of these new SBCs. Aarch64 lost a lot of the ‘magic’ of Aarch32, and looking at the RISC-V ISA, it looks interesting. Thank you for a great video!
OMG you touched grass, that's like unheard of in Computer engineering
Honestly a lot of computer scientists love nature, I suppose you get tired of computers working with them all day. I know I do
@@pinekel8987 yeah but not everyone works on the Google campus with greenery everywhere 💔
@@ChanakyanStudent7971 I mean... parks and hiking trails exist?
It's a green screen :0
why touch grass when you can code grass
One of the best explanations about vector processing, I’ve been looking for a simpler explanation like this since I’m a newbie
rather detailed but still concise way of explaining thing!👏
First time here. I think TH-cam brought me here bc I just finished up the show "Devs" and have been watching videos on quantum computers. Vector processing seems like another example of how the future of computing isn't here for consumer electronics (yet) but possibly better suited to help in the large calculations needed to help expand knowledge of physics, nature, etc.
Seems like vector processing might be a really good match for interacting/interfacing with quantum computers.
Also also, I had a micro controllers professor that said programming in C is like driving and automatic, while programming in assembly is like driving a stick shift. Might not be the best analogy, but your statement at the end made me think of that. Compilers don't always know best, especially since the instruction set is so new.
Intel cpus had vector instructions since a long time. Developers just need to know how to use them or compilers should optimize code that uses those instructions instead of what programmer wrote, recent c# compiler dose that.
Please don't take this first statement the wrong way :
I chuckled for a moment hearing your "little girl-like" voice.
As the outward expression of a highly intelligent and creative person, it is such a joy for an old, retired coder to hear and witness someone present things in a few minutes that many of us took years to understand. You have a long and very fruitful career ahead of you!
Best wishes and looking forward to seeing your next presentation.
Finally a channel I can watch to get a better understanding of underlying technology as a pastime, not as a chore
RISC is good. -Dade Murphy
Very nice serial experiment Laurie :D the code is similar to assembly, the structure of how the risc-v processor processes reminds me of gpu compute "hlsl\cg". the scalability could potentially be awesome. I'm looking forward to the future of open processing. Excellent content, thank you :)
i love how sound like cute vtuber, not like tech ytber
Thanks to THIS delivery, I'm now totally interested and invested in RISC-V, this is exactly what I want if I go SBC wise.. I love to fiddle with hardware and software since I had my Sinclair ZX Spectrum ( Yes, I'm that old!) and was following along through the SBC scene in search of that special something. Thank you for clarifying RISC-V Vector Specification to me. Disassembler-Editors and Machine code Compilers,your daddy is back.. 🙂
“Completely open and free to use.”
The US gov is considering changing that.
Really? I mean, I don't doubt they would want to do that, I'm just curious about the details.
@@SomeoneOnlyWeKnow. Because China has been working with the tech. US doesn't like that.
just wow. the recording, audio, editing, literally everything in this video is top notch!
Back in Uni - well before the new millennium - we had this concept of singly, doubly and triply hot women: physically appealing, mentally capable and/or a friendly/helpful heart. Of this set of {pretty, clever, nice} most women have up to two traits - pretty+clever has no need to be nice, pretty+nice is rarely clever, nice+clever is rarely pretty. Having all three of these traits was considered very rare, especially among students of machine-assisted maths (which was renamed computer science later).
Having all three traits AND being a fellow nerd was so rare that even just briefly meeting such a quadruply hot woman was worth remembering for life, a cherished memory on the same level as, say, having talked to Brian Kernighan in person. I know this isn't in person and therefore only counts half at best, yet still I am so grateful to have found this channel. Can't wait to watch everything released so far and everything yet to come.
High-quality video with exceptional clarity and visual fidelity.
Just took a graduate course in advanced computer architecture.... this vid is spot on! nice work. This would be a cool little board for CS majors to experiment with to get a grasp on RISC-V
Whats the vector Victor?
Surely you know, Shirley.
I love the fact that the whole style of the videos have changed, BUT still keeps in line with what we know from you with the Laurie Wired windows in the corner and all of that. A mix of old and new 🔥
Thanks for keeping it post, Laurie
It's amazing the quality of your videos for every new one. Congratulations. We love you Laurie ❤️😊

I’ve never seen someone so succinctly drop a SIMD explainer in my life.
Subbed, the production quality and information density alone makes this a winner
I swear at the beginning I thought a Kid was speaking XD
Amazing video! Your skillset is incredible. From programming, filming, editing to presenting. I just found this channel through a short and I immidiately subscribed. Love the aesthetics.
I love your content ❤
Thank you so much for this video and for your work in general! This video is amazingly edited and you make this topic interesting and easy to understand. And ofc I'm glad that you encourage people to learn low-level computer programming
Me: "Why is this so niche?"
Laurie: "You could say this ISA is...risk-vy"
Me: "....."
Laurie: 😜
I like the transitions done to visualize the devise and drill down to the scheme.. Top notch!
The voice is too cute.
Simply amazing video. Easy to follow to me, a regular PEBKAC. Engaging and well produced without getting in the way of the content.
Thanks
RISC-V propaganda! x86-64 will not be defeated-
*Draws 200 W and melts itself*
wow, really enjoyed this video, nicely paced, fun and no fluff! also had to smirk at all the Lain references, great taste!
How long have you been in the industry? I get the sense that the only way you could be detached enough from your work to humanize your content would be if you had at least 15 years of experience.
The editing on this is insane. Semi long time viewer of the channel, looks like I'll be watching this tonight. Great work Laurie :)

Thanks, first thing that helped me understand why I might care about RISC-V
