The sheer energy and enthusiasm in this video is just exemplary beyond measure. I think there's something to be said for claiming that 'if you imagine that a proportion of viewers might find it overwhelmingly intense, that'a not necessarily a bad thing for certain kinds of material'. There is an unmistakable impression of a wealth of in-depth and up to date knowledge and extensive valuable experience which sits behind the talk, combined with a serious commitment to helpfulness (evident in the on screen corrections and tips) that makes this video something that I intend to use as an instructive example of how to tackle an introduction to a difficult technical subject. Thanks and bravo Dave.

calm down!!

@mayorsnorkum4005 6 років тому

Yeah, amazing. I'm going to be watching his other videos, for sure. He needs to make a video about Root Canals, or mowing the lawn. I bet he could make them sound like good things :) Good on you, mate.

@bjtaudio 5 років тому

It very frustrating, programming this stuff, that's why he is carrying on...that are complicated...I hate programming anyway.

@BillAnt 5 років тому

FPGAs are usually used in circuits which need extremely high processing speeds often in parallel and independent of the main controller, like IP transceivers, data buffers, and even bitcoin miners (which go even further using ASICs). It's also used in vintage computer and console emulators (i.e. Jeri Ellsworth's C64 Direct-to-TV), usually for its high processing speed of graphics and sound data to minimize lag. They are also great for breadboarding/experimenting before committing to production ASICs. It's incredible flexible, but also fairly complex to develop it, therefore it's best used for niche applications.

Dave I just wanna say thank you for doing this stuff. I’m in my final year of a computer engineering degree and can confidently say that 2 days of me mucking around with a dev board + your videos has always taught me more than the related class at my school. I’m finally in a place where I can start donating back to you and will set that up soon. Just wanna thanks from college kids everywhere. If it were up to me I’d split my tuition between you and a couple others

@sky44david Рік тому

This is the clearest and best general introduction to the FPGA that I have found. I am using it to educate persons who work for an investor of my small company so that they understand the importance of why we are spending so much on XILINX as the core of our I.P. I started with Microchip's PIC in 1993 and on to XILINX's simple CLPD types and am still growing learning and adapting to vast progressive expansion that XILINX has made in decades of FPGA advancement. Thanks for making this educational reference.

@eveneevee27 4 роки тому

The best intro to FPGA I have heard of. Easy to understand and pretty thorough :)

@drteeth7054 8 років тому

This stuff is pure magic, especially when things are explained as well as they are in this video.

@poopytowncat 10 років тому

I've worked in electronics over 35 years as an engineer. I learn something new and valuable in every one of Dave's videos (including FF's). From my knothole, the info is about 100% practical and right on. Entertainment 100%. Thanks Dave!

@MatrixOfDynamism 10 років тому

I have worked as Applications Engineer for Altera FPGAs and have the opportunity to see them inside out. In many cases it is possible to use MCUs, but the flexibility that FPGAs provide in the present generation devices is just mind blowing.

@paulolivares8352 5 років тому

Thanks! I'm going to get started on learning fpga's! It's really awesome when you have an great person teaching! You're doing the world a great service!

@TimmayLaw 10 років тому

Just want to say thank you for these videos.. I've been working as an EE in the automotive field for 5 years now and a lot of these videos really touch on exactly what we have to work with while doing R&D! You have a great way of taking more complex subjects and making them a lot simpler, thank you!

Great lecture, Dave. This answered many questions I've had about FPGAs for years. Thank you!

@rallokkcaz 2 роки тому

I watched this video 7 years ago when I started trying to cram EE knowledge into my dumb head. I just wrote my first FGPA program the other day and realized this video helped me so much! And I haven't even seen it again in years, best content for EE on YT.

@EEVblog 10 років тому

Hard silicon CPU's are generally much faster and low power than "soft" CPU's. That is why a lot of FPGA's now have hard silicon CPU's built in them. In terms of older CPU like say a 6502, an FPGA soft core can be much faster than the old chip.

@sauronbadeye 8 місяців тому

Many Years ago I designed a board that was based on an Altrra Fpga. It integrated a Z80 core ( that I downloaded from Opencores!) 2 Darts, 2 Ctc, a PCI slave logic and other stuff... the Z80 was able to run at the speed of PCI bus at even higher!! But in general it is not a good idea to integrate a CPU into a Fpga, especially if it has to run at high speed!! Moreovrr FPGA are power hungry.....

@rfrayo_ 3 роки тому

I wish you taught my embedded systems class. I attended 40+ lectures and have still only scratched the surface of FPGAs. We did do some cool projects with them though. Your methods of explanation were far better than my professor's. The best lesson you can learn from applied computer science is "computers are stupid...that's why you have to be smart to figure them out."

@joshuantw 4 роки тому

love your energy and the lilt in your voice man! great explanation so far I'm on the 7 minute mark, excited to learn more!

@TheRopez94 10 років тому

Love the topic Dave, as a computer science major my focus is in software but I love hardware just as much and your videos always help renew my desire to study EE. Thanks a bunch

@cny02253 10 років тому

Really great overview of FPGA basics. You have to know which country you are in before you can efficiently know which specific street to drive down. Many people seem to want to skip the fundamentals, but especially with FBGA's -you do that to your great disadvantage. Its easy to get lost in the trees in the FPGA forest.

@hassaankhi 7 років тому

At 11:17 I like the way you stressing. "Anything" :-) Thanks for the lecture.

@GRAYgoose124 10 років тому

I bought an FPGA dev board a few months ago and designed a 16-bit processor, these are really great.

@preben01 10 років тому

@FPGABeginner 3 роки тому

I tried to start with FPGA programming, but didn't really get my head around it. I found the VHDPlus IDE and with the simple language, embedded libraries and other features it helped me a lot to make some cool projects :) Just in case someone has the same problem

@obiwanjacobi 10 років тому

Thanx very much. I knew a little bit about FPGA's but this was really tying it all together. I wouldn't mind a couple more of these at all! Excellent stuff.

@conorstewart2214 4 роки тому

Gotta be one of the best UKposts channels, with covid-19 meaning I have to watch my university lectures at home I usually speed them up because they talk too slow! Not with this guy though, great enthusiasm and packs a lot of information in a small period of time as well as being some of the best information on a subject you can find on UKposts. There are very few videos on UKposts I’ll watch for over 30 minutes but this was exceptional.

@tixgy 10 років тому

Very informative and very well explained. I was curious about the FPGA the other day. I found this video very educational. Thanks Dave! :)

@shanesrandoms 7 років тому

When seeing the Data sheets for the Cyclone IV series I've been playing with lately, one realises that in the modern day, no engineer can really understand everything without still having decent reference material :)

@djruido1 5 років тому

Shane Van Ingen is it that bad? I’m just an enthusiast and you just made me feel better on my level of understanding of this chips lol

@monelfunkawitz3966 5 років тому

@@djruido1 Yes. With power comes complexity. Imagine making a cpu out of transistors. The assembler DOES do alot of the grunt work, but it will push the limits of your understanding. They are TRULY intended to be engineered for a mass production project. If as a hobbyist you want it to do what an Arduino or PI can do, save yourself alot of headache and go that route.

@bitsurfer0101 9 років тому

Hi Dave, I find your tutorials useful and always helpful. Could you do a little bit on how to map sequential logic and how to implement this on a fpga? Some state diagrams would be helpful.

@pranitoza3966 2 роки тому

The only video on the internet which gives a proper explanation of FPGA (trust me I am saying this after watching a lot of crapy videos on FPGA introduction).

@gateway8833 10 років тому

Dave, I looked up FPGA's on dig i key the most expensive one was $39,452.40 (USD) It has 152700 CLBs. I am going to have some fun this weekend. Thanks for making these videos, they really help.

@0LoneTech 10 років тому

Like Dave said in this video, these blocks contain more than just buffers. Typical capabilities include differential pairs, bus keepers, pull up/down resistors, and doubled up flipflops for DDR functionality. The simplest ones are just a buffer, though; typically on dedicated pins like clock inputs. Those still get special treatment in their connections to clock nets, PLL blocks and such.

@ISmellBurning 10 років тому

I qualified as an electronics repairman over 20 years ago. I left EE for software, but have recently returned as a hobbyist. FPGA's are a complete mystery to me but now I have at least a vague understanding of what they are & I'm also able to look into the 2 main players programming languages so I can choose one to learn. So in short, this video is actually generating sales (I'm buying a dev board!) while also filling in some of the 20+ years gaps in my knowledge! You can't really knock that!

Behavioral abstraction levels in modern HDLs really help to make them much more approachable and intuitive. It is still definitely a different animal altogether insofar as inputs and outputs are predefined and can be things like wires or registers and such, but behavioral abstraction at least affords you syntax that is more akin to a normal PL such as C.
