What's an FPGA?

In the video I give a brief introduction into what an FPGA (Field Programmable Gate Array) is and the basics of how it works. In the future I might go more in-depth about certain topics relating to FPGAs/ASICs and CPUs, such as how synthesis or compilation works, or topics like retiming and lower-level FPGA architecture.
This video was mostly made for me to practice doing animations and graphics all with Python and trying to experiment with developing my own style/aesthetic.
Animations made using Grant Sanderson's (3blue1brown) wonderful "manim" Python animation engine: github.com/3b1b/manim

Apologies for the shameless plug here, but since making this video I've started working at Intel in the FPGA division (*now Altera again!). If you want to see some more FPGA-related tutorials by me, feel free to check out my introductory high-level synthesis demo on the Intel FPGA channel here: kzfaq.info/get/bejne/o7d7ibSbr9StqnU.html

How would you make your lookup tables "programmable"

@g.d.8065 4 жыл бұрын

A lookup table is just some memory that contains some set values, so you can make them programmable by storing them on rewriteable memory. In this case, the lookup tables are being used as logic gates by taking the individual address bits as the inputs, and the individual bits of the value stored at that address as the outputs.

Instead of writing the code that you upload on a microcontroller, you write the code that transforms the fpga IC into an actual microcontroller. Basically if you know how an existing IC is made, you can recreate a copy of it by writing its code. The next day you need something else, let's say drive a display, then you write (or download) the code, upload it on the fpga, and you have another device. It's similar to the concept of 3D printing applied to electronics.

@NoSpeechForTheDumb 5 ай бұрын

@@midclockconfiguring an FPGA as a microcontroller is only one of infinitely many applications. It's not even mandatory, you can as well have a dedicated external microcontroller which communicates with the FPGA over PCIe, or no software at all. That's hard to imagine in our software-focused world of course.

@midclock 5 ай бұрын

@@NoSpeechForTheDumb well I've bought one, but honestly it's still too much for me. I think that anything that can be built inside a digital IC, can be ideally replicated into an FPGA, but I'm not sure about it. Even if you learn VHDL or similar, I think that knowing digital electronics is mandatory before writing any code. I hope to learn it in the future, it's a fascinating topic!

@crclayton 9 ай бұрын

It depends on the application, but yes there are situations where an FPGA could be a good replacement for a CPU based system. Particularly where low-latency, high-bandwidth, or high-parallelism are required. FPGAs can also be programmed to actually implement a CPU within the FPGA fabric alongside other logic (ex. Nios V).

Can the FPGA reprogram itself at runtime?

@crclayton Жыл бұрын

Yes, there are some techniques where the FPGA can download an image from an external source like a PCIe link or flash memory, then reprogram a section of the FPGA's logic while keeping the other logic consistent.

@@crclayton Consider the advantages of writing a function where parameters are not passed, but rather the code is modified before calling it (if necessary), or where optimization is performed just in time before execution.

I would have at least mentioned that it runs much faster, would have taken 5 seconds.

@crclayton Ай бұрын

I suppose I could have, but that would be a broad and incorrect overgeneralization. Runs what faster? By what metric? GPUs, CPUs, and FPGAs all have different applications and strengths and weaknesses. FPGAs can't operate at anything like the frequencies CPUs can run at, but they allow for flexibility and parallelism and ASIC modeling. FPGAs don't really "run" anything, they implement a circuit and some circuits are fast and others aren't.

I like to think FPGA is for emulation haters. I wonder if there’s a group of people who dump on emulation for whatever reason or for inaccuracies and crashing and will always stick to real hardware whenever possible until FPGA happened. I’m not an emulation hater, I’m just asking if you’ve seen people like “emulation sux!!! real hardware ftw!!!”. But I like to think FPGA gives emulation a run for its money and will probably replace it in a few years.
