Arm made a bendable 32-bit processor out of 'plastic'

Why it matters: As you can probably attest, modern wearables can be slapped on a wrist or slotted in an ear without a problem. But they’re not subtle enough, neither in their design or cost, to be part of everyday items like clothing, milk cartons, food packages, or bandages – Arm’s examples of places where their new "natively flexible" processor might belong.

In a new paper published in Nature, Arm researchers explain how they ported a standard 32-bit Arm processor design onto a plastic substrate that they say is bendy. It’s more of a proof-of-concept than a working prototype, but it nevertheless demonstrates some significant firsts.

Arm fittingly call their creation "PlasticARM." It uses metal-oxide thin-fin transistor technology (TFT) fabricated on a polyimide substrate. Polyimide is a durable type of thermoplastic that’s mildly flexible. Arm’s team wasn’t willing to put their processor’s flexibility to the test, but I would estimate that it lands somewhere between a watchband and a pen on the bendiness scale.

PlasticARM’s package is roughly the size of a fingernail. It has 18,344 gate equivalents spread over an active surface area of 59 mm2.

About half of its area is a 32-bit Arm Cortex-M0+ processor, and the rest is mostly 128 B of RAM and 456 B of ROM. It is a full system-on-a-chip (SoC).

One of the reasons why the researchers chose to use the Cortex-M0+ design was because it has a mature ecosystem, but the PlasticARM can’t make much use of it yet. Its storage was configured to be read-only to streamline its operation, although a reprogrammable model is in development.

It has other shortcomings, too. Under normal circumstances, a Cortex core has registers inside itself to store regularly accessed data, but they were offloaded to a section of the RAM for simplification purposes. It’s also limited to 29 kHz while most Cortex-M processors measure their speed in MHz.

Most of PlasticARM’s problems will soon be solvable but one that will persist is power consumption. In testing, the processor consumed 20 milliwatts, which is several orders of magnitude beyond the standard range of a Cortex-M processor. Arm’s team expects to be able to shrink the disparity with future iterations, but says that low efficiency is an intractable quality of TFT designs.

"It won’t be fast, it won’t be energy efficient, but if I’m going to put it on a lettuce to track shelf life, that’s the idea," Arm’s James Myers told New Scientist. But "we’re still looking for applications, just like the original processor guys in the 1970s."

They are years behind the chip I took with my COVID vaccine.
Even if it were true (like someone hasn't already tried to prove it) don't break the law, and you have nothing to worry about. I'm lost already brother because unlike most Americans I have a Smartphone, a tablet and internet access.

The only use I can think of for a "bendable" CPU, would be that were it equipped with tungsten carbide pins, about 4 mm in length, you could hammer it on to a persons skull. Which could come in very handy for mind control / mind reading experimentation..

Oh sure, the installation might smart a bit, but just "think", it might prove a gateway to full telepathic abilities. (Obviously only with others likewise equipped and with native blue tooth capability).

And there you have it boy boyz, gurl gurls, boy gurlz,and gurl boyz, my first full bore sh!tpost of the day.. :rolleyes: 🤣

You joke... yet there are so many people who believe that nonsense...
They probably also believe that because of that chip, they are being targeted by "space lasers." 🤣

For a metaphorical treatment of that subject, Commander Airiam from Star Trek: Discovery goes a long way - https://memory-alpha.fandom.com/wiki/Airiam#:~:text=Lieutenant Commander Airiam was a female Human cyborg,,USS Discovery as the spore drive ops officer.
I am surprised that Musky wants to have something similar hammered into his skull with his fear of AI. ;)
Thanks for the sh!tpost. I got a laugh out of it. 🤣

So then, "Data", with a gorgeous a**?

The couple of episodes of "Discovery", that I endured, seemed more like a training and propaganda vehicle for the advancement of the LGBTQ, agenda. I'm honestly amazed they were "restrained enough",. to not paint rainbows all over the saucer section. (As I walked away muttering to myself, "dear god, I hope they renew 'Seal Team'")...

But, pay me no mind. I'm probably the only person,,sorry, I meant "Trekkie", who enjoyed the supposedly "cringe worthy" intro song to , "Enterprise". (Hint, it was played on the 12 string). Not to mention Jolene Blalock's "non standard uniforms". But seriously, that woman had the most beautiful posture. Scott Bakula.can't act to save his live, but he did OK in that series.

Back to topic. From what I've run into on the internet, a 32 bit mind control CPU is probably way overkill. Most of those on Facebook and Twitter, are 8 bit chippers, max.

Although I still haven't figured out how to make contactless payments with It...

It's not funny. There's no chip inside, but there is graphene oxide. Which at room temperature attracts anything ferromagnetic, including erythrocytes which contain iron. They surround the graphene particles, causing micro-clots. Which can damage extremely thin blood vessels in lungs. Not only it decreases the function of lungs, but it makes extra pressure on heart pumping the blood. Eventually leading to coronary or lung problems, and death. In younger people it will just cause infertility. At least that's how the "population control" system should work in theory.

But we'll see. Maybe this is just a conspiracy theory. In about 4 years if there's enormous number of deaths, we'll know that it worked.

That is a complete lie... there is no graphene oxide in any Covid vaccines!


At least do a fact check before you spread misinformation here...

and if there is more deaths like on covid we will know it worked too! genius
