Intel powers an Arduino for the first time with new “Galileo” board (ars technica)
Ars technica covers Intel's announcement of the Galileo development board, which contains a Quark 32-bit x86 CPU and is targeted at the "Internet of Things". It was designed in conjunction with Arduino and has connections for existing Arduino "shields" in addition to USB, Ethernet, RS-232 serial, and PCIe. "Intel will be donating 50,000 Galileo boards to universities around the world as part of the collaboration, and it will be available to hobbyists for $60 or less by November 29. That price makes Galileo quite competitive with existing Arduino boards, most of which aren't as feature complete. Intel promises full compatibility with Arduino software and existing hardware, which could make this a very attractive board for complex projects." Galileo is also open hardware, with schematics and other information available at its home page.

It it just me, or does it seem that every time someone creates a new and interesting computer not based on the Intel architecture, Intel launch an inferior alternative that has less performance or uses more power, costs more, and then use their marketing prowess to try and make it stick?
OLPC -> Classmate

It's not just you.

The problem is, I've never heard anything more of those on the right-hand-side. Intel just don't know how to compete in that area, so they have to trail by which time people don't touch them.
It's a shame - a Pentium-on-a-chip would have sold millions some years ago. Now it's just a waste of power. I still have a NetPortExpress based on a Intel 386SL chip, they obviously knew how to do this stuff at one point, but it's just a question of power, heat and size which Intel haven't been very good at for a long time.

It was not “heat and size” per se. Intel manufactured Intel 80376 for many years, after all. But it refused to license cores and it refused to make a proprietary SOC designs on it's own fabs which made them useless in a time when everyone started switching to custom SOCs with CPU just one small part of the whole chip.

On the other hand, it has real mode and vm86!

Seems a perfectly reasonable strategy. The devices you list as their targets are all cheap. Producing an equal or superior alternative at a similar price would risk cannibalising some sales of higher-end Intel processors. This way, they hopefully muddy the waters and reduce sales of the competing device without diverting too many people to the bottom end of their product range.
Intel powers an Arduino for the first time with new “Galileo” board (ars technica) Posted Oct 4, 2013 12:24 UTC (Fri) by stumbles (guest, #8796) [Link] Aye, its called pissing in their (the competitions) Wheaties.
Intel powers an Arduino Posted Oct 4, 2013 17:12 UTC (Fri) by pboddie (guest, #50784) [Link] From the FAQ: Can I use this board without a power supply? Intel certainly aren't doing much to lose their reputation for excessive power consumption. The Arduino Yún can be powered from the USB port, just like many of the other boards. Anyway, the Arduino product page is arguably a better summary for those of us who don't enjoy downloading PDFs as much as those in the semiconductor industry seem to. Still, it's nice to see additional diversity in this scene.
Intel powers an Arduino Posted Oct 4, 2013 21:05 UTC (Fri) by khim (subscriber, #9252) [Link] It's also funny to compare these three lines: 1. Arduino Uno: 32 KB (ATmega328) of which 0.5 KB used by bootloader So it's hundreds of times more powerful then typical Arduino, about 10-20 times more powerful then ARM-based DUE, but all that power is actually used just to boot it up? Ouch. Still it's nice to have somewhat overpowered "big brother" in Arduino family. But more testing in the field is needed before we'll know what can you use it for.

Such is the price of having hardware convert the x86 code to something the processor can process.
Intel powers an Arduino Posted Oct 6, 2013 2:40 UTC (Sun) by oshepherd (subscriber, #90163) [Link]
Erm, what?
The processor in this thing runs x86 code. That's, you know, a prerequisite of being an x86...

Intel (and AMD) processors are actually RISC. They have not produced a true CISC processor since the Pentium 2 I think.
What they do have, however, is a hardware translation layer that dynamically translates x86/x86_64 machine code to another machine code format that is actually executed on the core processors.
The x86 or x86_64 is the 'ISA', a standard language interface of sorts. Another way to think about it is that you really have a x86 'virtual machine', but instead of doing the processor emulation in software Intel does it in hardware.
This is a very complex thing to do in hardware and maintain good performance. Normally this is not a big deal because the logic required to do the translation was much smaller then the rest of the processor, however as Intel tries to simplify their processors and scale them down they can't get away from the huge ISA translation layer.
ARM, on the other hand, comes out with new architectures on a regular basis. They don't mind breaking their machine language compatibility and will add and changes things as they see fit.
This reflects the different goals and successes of the original architectures.
This one of the major reasons why ARM has, so far, been ahead of Intel in terms of performance per watt even though people that license their processor designs have cpu manufacturing processes tend to be a few years behind.
Intel powers an Arduino Posted Oct 6, 2013 10:56 UTC (Sun) by khim (subscriber, #9252) [Link] Intel (and AMD) processors are actually RISC. They have not produced a true CISC processor since the Pentium 2 I think. Apparently it's still true for AMD, but no longer true for Intel. I'm not 100% convinced that it's just a shrink of P54C but something like this highly likely: this will explain all observable quite well: that's how you can make it five times smaller and ten times more energy-efficient then Atom, etc. Five times smaller means that it has about the same number of transistors as Pentium !!! core and there are a lot of other things besides core!
Intel powers an Arduino Posted Oct 6, 2013 12:31 UTC (Sun) by pboddie (guest, #50784) [Link] I'm sure you can dig something up about this, but I'm also sure that various AMD product lines went through a transition to RISC (or started out life as RISC) with some kind of x86 translation being used to satisfy the needs of everyone who can't manage to recompile their software. See this page on the Nx586 with a note about RISC86 instructions, for instance. Of course, AMD have acquired technologies that should have allowed them to put desktop-class products into low power devices. The Geode CPUs (which will supposedly be discontinued fairly soon) are an example of this, although they apparently use traditional microcode implementing x86 instructions directly. Maybe AMD didn't see any future for this approach either in terms of power or performance, effectively bringing to an end a product line that in fact originally came from another x86 competitor, Cyrix. The NexGen approach was the one that worked best for AMD, I guess.

In SoCs like Quark, the *entire* CPU core is small compared to the rest of the SoC anyway.
I suspect power is a different question than you think it is.
Intel powers an Arduino Posted Oct 6, 2013 17:39 UTC (Sun) by khim (subscriber, #9252) [Link] In SoCs like Quark, the *entire* CPU core is small compared to the rest of the SoC anyway. That's true for most SoCs, but I doubt it's true for Quark. Quark is billed as ⅕ of Atom. Atom has about 50 million transistors thus Quark should have about 10 million. If you'll recall that even original Pentium had 3.1 million and also consider the fact that Quark is supposed to be synthesizable we should expect between 3 and 5 million transistors just for that single core. That's hardly small compared to the rest of the SoC anyway. P.S. Of course Intel could have used 80486 core which only had ~1.2 million transistors but in that case it's 400MHz will deliver pretty pitiful performance by today's standards thus I hope it's at least Pentium-class CPU. And even in that case it'll be ⅒ of the whole SoC!

Inside the 8M SPI there is:
- EDK2-based firmware (BIOS) - GRUB legacy - a Linux kernel and a tiny but functional Yocto system.
Arduino sketches run in user space.
The "bootloader" term is only kept not to confuse Arduino users - some haven't and will never hear about Linux.
Note GRUB is configured to boot (a bigger) Linux system from microSD (or USB) instead of SPI when a GRUB config file is found there in a predefined location.

There are quite a few USB-powered devices with an ARM (Cortex-Ax) core out there. They are about the same performance level as this board.
Intel powers an Arduino Posted Oct 5, 2013 15:29 UTC (Sat) by khim (subscriber, #9252) [Link] Sure, but can they be used with Arduino IDE?

> Sure, but can they be used with Arduino IDE?
I am not sure if this is a advantage or not. You have a PC-like, which could hosts a real OS, which all the capabilities:
I think that thinking this board as an Arduino compatible board is quite limiting. You have the cons of both the world (low power, low storage of Arduino and high consummation and a complexity of an x86 board)
Intel powers an Arduino Posted Oct 6, 2013 11:31 UTC (Sun) by khim (subscriber, #9252) [Link] I think that thinking this board as an Arduino compatible board is quite limiting. Oh, sure. But the important thing is that this is “Arduino board plus something” (similar to Arduino Yún in the spirit if not in capabilities). It's easy to create cheap development board (think STM32), but if it's not in “Arduino family” then people can not start using it easily. The only gain is that an hobbyist can start from a quite know environment. Sure, but this is large gain. Before you can learn to run you need to learn to walk! That's why Arduino (which is very underpowered and significantly overpriced) is so popular! And if you started with Arduino then obviously you'll want to work with something Arduino-compatible.

Arduino TRE: http://arduino.cc/en/Main/ArduinoBoardTre
Intel powers an Arduino Posted Oct 6, 2013 11:09 UTC (Sun) by khim (subscriber, #9252) [Link] Well, to me “is expected to be available in spring 2014” means “it's not available right now”. And it's also very different from all other Arduino boards. But yes, when (and if) it'll become available it'll be interesting to compare it to Intel Gallileo. A lot will depend on price. Beagleboards are $45 nowadays and this thing is somewhat more complex then Beagleboard thus we are reaching the same $60 ballpark as Intel Galileo, but a lot of things can happen in the next half-year!
