They mention APIs for Windows, Linux, OpenSolaris, a ZLIB, and the Apache module. http://www.aha.com/DrawProducts.aspx?Action=GetProductDetail...

The article mentions designs where the muons can circulate 2000 times, so I think this publication is assuming some conceptual knowledge on the part of the reader. Muons are generally produced by hitting a target with a beam of something el

Very interesting stuff. I wonder, did you try -1 (0xFFFFFFFF)?

It's interesting to consider the N64 in contrast to the first Voodoo card. One is a console and the other is an add-in card, but both launched in 1996, with underlying 3D technology from SGI. The Voodoo used EDO RAM, 8 chips of 256k x

The person you're responding to probably worked with DSP chips, which are generally not floating-point. e.g. Motorola 56000, TigerSHARC, Blackfin.

Thanks, looking forward to reading more. I am a hardware guy, but I see using higher-level languages to generate HDL as being a very powerful approach.

Great stuff, cool project. Could you share a few thoughts on your language and transpilation approach?

Wow, the Z1C is pretty old. Do you have any trouble with battery life? I used to run a Z3C, but after some of the seals got loose I upgraded to an XZ1C. It's near perfect for me, and I don't know where I'm going to go next fo

I used to be bothered by reconstructions, especially ones rebuilt in the 20th century. But since then I've realized just how fragile and transient buildings can be, and how much effort it takes to maintain the ones we've got. If i

I spent some time looking through the NTSB docket today. I was a little surprised that Apple was willing to provide logs from a development model iPhone. Evidence seems to point to the victim playing a game while commuting -- in my opinion

Did they tell you exactly where it blew up? Then it might be fair, 2 pages is not that big. Though you'd still be at quite a disadvantage compared to someone who spent a lot of time designing the thing. I gotta say though, if they them

I had to replace the switches in my G100s after a few years, first the scroll wheel button and then the left click. Definitely an unacceptable level of longevity.

"High Speed Digital Design" generally refers to PCB level design. The Black Magic books are pretty old, covering ancient stuff like DIP packages on manhattan-routed boards. These days the keyword is SI/PI (Signal Integrity, P

Even a fabless semiconductor company (e.g. nVidia, Apple, heck, AMD) needs to spend hundreds of millions to tape out a leading-edge IC. It's a capital-intensive business, and would present quite a risky bet for any upstart competitors.

Most American whiskeys require new charred barrels, corn whiskey being the most common exception. See pages 21-24: https://www.ttb.gov/images/pdfs/whisky-webinar.pdf

Here's a greatly simplified example. Let's say you're trying to calculate y = mx + b in your FPGA. You want this operation to run at 100 MHz. Great, you write the code, synthesize and implement. Uh oh, the tools report that y

I'd be curious to see what shorting across the transistor would do. It would probably reveal whatever behavior they wanted to avoid.

Wow, that was quick. Given that this is Broadcom, I don't suppose there is any visibility into the Root Complex? When troubleshooting PCIe it'd be nice to have the LTSSM state at least. Would be really cool to get eye diagrams...

So I think you don't need to measure the capacitance per se. Instead you use the capacitances to make a series of (AC) voltage dividers. The lines that are individually broken out (call these the vernier lines) will have different degr

If you've not been previously exposed to stuff like Lagrangians and Hamiltonians, I'd suggest Taylor's Classical Mechanics text, which is quite friendly.

When you say the power was cut to your USB keyboard, could it perhaps have been reset and in a unenumerated state? If you have a multimeter it could be useful to check the various power rails in the bad state. Try running Memtest86 and lowe

I went from Z3C to XZ1C last year when the rubber on the USB cover piece stopped working right. After getting used to the look, I like it a lot. It's a more physically solid design.

That SoM is well within KiCAD's capabilities. Layout is not the issue. The fraught part is designing the DDR4 interface -- a pro shop will pay out the nose for a signal integrity tool like Hyperlynx to do simulations. While in theory y

At my work we use a COM Express module that has a Potato Semi part on it. Gotta wonder what the backstory is on that company.

The point is you are limited by the capability you build in at launch, SDR or otherwise. The hardware side is more restrictive than the software side.
56.
by mng2 8y ago
That really is the elephant in the room where SDR is concerned (along with front-end). More realistically you could change protocol/encoding after launch.

The Snickerdoodle got a lot of attention for its price point (which turned out to be unrealistically low... I commend them for following through though). It's an odd platform. They were going for an ecosystem of carrier boards, but end

To be fair, specs and standards generally aren't written as introductions, so they're kind of hard to make sense of when starting from zero. USB, with its infernal descriptors and endpoints, benefits mightily from third-party expl
