I just googled it and they seem to be MCUs with no programmable logic? What feature gives them a taste of an FPGA?

Whenever people ask this question, I'm the broken record with the same reply: start out with the cheapest kit possible, an Altera EP2C5TQ144 development board. http://land-boards.com/blwiki/index.php?title=Cyclone_

AFAIK they are printed on demand when the volumes are low. It's incredibly easy to publish (you're essentially uploading a .pdf file). I assume that tons of books only sell a handful of copies. E.g. the only copies of a book that

There are plenty of people who can deal with a rational explanation about why they are wrong, but who are not able to deal with being bullied. As I wrote in a different comment in this thread: I would never consider contributing to the kern

A distance character with the stature of Linus rebuking in public would make it so much worse for me. I'd be terrible at being a celebrity.

I disagree strongly with his personal 'no BS' attacks. For some people, it's a huge deterrent to make contributions. I've participated in a number of open source projects. I like to think that I've made useful sug

I expected that somebody would prove me wrong about the VGA thing. Very nice project!

by TomVDB 8y ago
For hobby projects? Multiple reasons: - because writing RTL is fun, while writing C code is boring. :-) - because it's probably not possible to outputs VGA with your standard microprocessor. You can create a dinky 3-bit VGA output with

Word of warning: my UPDuino v2 (these have a USB connector so you don't need a separate programmer) worked, but it heats up a lot immediately. I suspect a short circuit somewhere due to bad soldering. Requests to have it replaced were

My standard to-go-to FPGA is an Cyclone II EP2C5T144 development board. On a good day, you can find them for less than $5 on eBay. You'll need a USB blaster to program them, which adds another $10 or so. They are small, but they are st

My first ASIC was validated like that. A much larger wire wrapped board with a bunch of FPGAs. It only worked if you gently pushed with your hands into the wires, but it was sufficient to discover a bunch of bugs (that should have been foun

And how much of this additional cost goes toward medical cost? The US health care issue can only be solved by higher taxes and lower cost (it’s currently at 2x the cost of developed countries.)

There’s a huge difference between saying “we will have something in the future” (duh) and saying “we have absolutely nothing for the next year and a half.” The latter gives your competitor the freedom to ask any price the market will accept

Do you by any chance know how much RAM the CPUs in a render farm need? That would help to put the 48GB in context... Answering my own question: http://pharr.org/matt/blog/2018/07/08/moana-island-pbr

Is that a limited use case because not many workloads map to INT4 or has this Avenue simply not been explored because there weren’t any INT4 processors? My understanding is that during inference, precision is often not critical, and that so

I think it’s used to load all the geometry of really a complex scene with a lot of geometry. (Think Pixar movie.) With ray tracing, if you can’t load the whole scene in memory, it’s simply not going to work. Disney recently released a scene

Kepler GPU die sizes were pretty small. Maxwell die sizes on the same process were much larger. (Up to 600mm2.) Pascal die sizes were pretty small. The Turing die size is much larger on (essentially) the same process. You’re seeing the powe
