In fact, one is already in progress (the U500): https://www.sifive.com/products/freedom/

The OP one seems to be different - for example, it doesn't list stb_vorbis.c.

GPU drawing can still be faster than on the CPU, and you can do that with Wayland, by directly opening the DRM device (/dev/dri/render*) and sending the rendering commands directly to the GPU. This is how Mesa implements Open

Yes. Some applications still use the XWayland compatibility layer, so they can snoop on each other, but not on Wayland apps. I think the only XWayland-using app that Fedora ships with is Firefox.

And it's also not GPL, which means that vendors will be able to create fully proprietary versions of it. Yay?

This is one thing that Stratasys totally missed out on. They are heavily reliant on support material and other consumables, which is great for making arbitrary shapes but not for cheap production.

I still frequently end up crawling back to OpenScad. It is often quicker than the rather click business of setting up constraints. Just don't ask me to make a rounded corner in it.

It obviously can't work for a lot of applications on its own. Another limitation is that blocks are only every 10 minutes, so you're at an hour wait for the recommended 6 confirmations. Worst case, you could imagine most Bitcoin t

An easier solution would be to enable e10s. It should be on by default in the next ESR, and I know TBB has been working to make their patches compatible with it.

Yeah, even with the Opus application I mentioned, 320Mhz is way overkill - 50Mhz would have been plenty. It kind of seems like for some reason they were able to get a modern process, but only a really tiny die. It's pretty interesting

Too late to edit, but I meant to link to this page, which is more specific about this chip's implementation: https://dev.sifive.com/documentation/freedom-e310g-0000-manu...

by TD-Linux 10y ago
Yeah, bit banging I2S would be gross. You could, however, use the PWM outputs for audio as long as the requirements aren't too strict. And of course, you could always implement it with extra hardware. Hoping for I2S on the next version

The limitation that I referred to (same as open-v) is that it's very difficult to get IP for embedded NVRAM, and requires more complicated processes. So this seems like the next best option. Yes, misses are going to be very expensive,

Firstly, https://xiph.org/~xiphmont/demo/neil-young.html Secondly, even if you did want to process at 96kHz, you'd have plenty of CPU left to do so. It's only 2x as intensive as 48kHz (this is a 32 bit C

That speed is quite enough to do audio processing - you can run Opus easily on those microcontrollers. Many other audio processing tasks are simpler. AC97 chips are basically DACs/ADCs, and do no audio processing themselves, so are a b

I looked over the Chisel source code and the barebones datasheet [1]. This chip has a couple of unique features: 1. It doesn't have any onboard NVRAM (same limitation as the open-v). However, it does have a directly memory mapped quad-

The chip linked is the E310G, which neither has a MMU or real OS kernel (same as Cortex-M). It also doesn't have most of the peripherals you listed (maybe you got it confused with their other, larger chip). It really is a Arduino compe

RISC-V has a head start - v2.0 was frozen in 2013, and j-core was first announced in 2015.

It's quicker and easier than submitting any patches upstream. They don't care about support past product release. Usually the SoC vendor provides the forked version, and the manufacturer forks that again, so they are twice removed

by TD-Linux 10y ago
How much are you willing to pay for it? There's the Talos Secure Workstation, which has no such ME firmware (but costs ~$4.5k) [1]. A RISC-V desktop is pretty far out. There is an Arduino style microcontroller being made in silicon, th

No need. Simple digital signatures of comments (and of their parents) would go a long way here.

It's not the first time they've used this license: https://github.com/facebook/transform/blob/master/LICENSE (in that case, they even used it to distribute a patch to ffmpeg, which is LGPL)

That's partly the case, though note that in terms of Bitcoin, stock would be considered to be centralized, not distributed, as the exchange determines ordering of transactions. It's not really proof of stake because it doesn'

Sadly, this article is mostly just a link to the Ethereum FAQ. It should be noted that every Proof of Stake altcoin has eventually collapsed, and there are arguments that this is inevitable: https://download.wpsoftware.net/b

It's common for many types of cells, but much more difficult for Sunpower cells. Instead of having top contacts, Sunpower cells have a fine array of contacts on the bottom [1]. Cutting this without creating shorts or defects is quite d

There are ways to do zero-knowledge proofs in Bitcoin too, for example: https://bitcoincore.org/en/2016/02/26/zero-knowledge-conting... It is pending a Bitcoin softfork (segregated witness) (edit: actual

See this picture of the Dragon spacecraft's panels: http://www.space.com/images/i/000/017/802/i02/spacex-dragon-... They are very clearly Sunpower C60 or similar, a high end mono-Si cell.

Er... Linux does use a similar time-based release schedule now, and the minor number has been reset a couple of times to keep it from "getting too high".

Yeah, manufacturers like Cree specialize in it for high voltage MOSFETs.

They are feeding in lat/long coordinates to the shader, and then doing the map projection there. Effectively they want lots of precision, but also the ability to represent coordinates anywhere in the world, in their shader. The alterna
