IBM Unveils the 'World's Smallest Computer' (mashable.com) 164

On the first day of IBM Think 2018, the company's flagship conference, IBM has unveiled what it claims is the world's smallest computer. It's smaller than a grain of salt and features the computer power of the x86 chip from 1990. Mashable first spotted this gem: The computer will cost less than ten cents to manufacture, and will also pack "several hundred thousand transistors," according to the company. These will allow it to "monitor, analyze, communicate, and even act on data." It works with blockchain. Specifically, this computer will be a data source for blockchain applications. It's intended to help track the shipment of goods and detect theft, fraud, and non-compliance. It can also do basic AI tasks, such as sorting the data it's given. According to IBM, this is only the beginning. "Within the next five years, cryptographic anchors -- such as ink dots or tiny computers smaller than a grain of salt -- will be embedded in everyday objects and devices," says IBM head of research Arvind Krishna. If he's correct, we'll see way more of these tiny systems in objects and devices in the years to come. It's not clear yet when this thing will be released -- IBM researchers are currently testing its first prototype.

        Well, you could have AI based sorting. Like sorting first on some heuristic parameter that isn't actually the parameter to be eventually sorted by.

        • Good idea. Why sort of the parameter to be eventually sorted on, when you can sort by something completely different first?

            Because the AI might be able to sort out certain things faster/to get clusters that may/may not be worth further sorting.

            I can think of one example, block-sorting file compression as used by bzip2. If you are making a tarball of several files, it will presumably help to have files with similar content next to each other in the archive. (The block-sorting process would rearrange them later to some extent, but I believe that compression will be a bit better if they are already close, particularly if the input data is much bigger than the sorting window.)

            So you first sort by some measure that only approximates sorting by conte

Do you think true AI isn't possible, or just the time frame is wrong? (Which it always is) Just curious because you always pop up in these types of discussions, so you obviously care enough to post.

    • This is nothing but an incremental change that does not have much of a bearing on AI, trips to Mars and quantum computing. I.e. there are obstacles in the way to those goals that this particular innovation will contribute very, very little, maybe even nothing, to overcome. Finally, the required breakthroughs will not happen if we just sit back and wait.

      • by Anonymous Coward

        I don't think it needs a motherboard. Look at the diagram:
        * PV power source, right there on the chip. So you don't need to plug into external power.
        * Static RAM data storage, right there on the chip. So you don't need a hard drive or anything like that.
        * LED communications and photo-detector, so you have input/output there.
        * x100,000 transistor processing unit. So there's your CPU.

        So you don't need a motherboard. It's entirely self-contained.

        • No. It needs a motherboard. It even shows it in the picture. As usual, this is BS. IBM was pushing "Smart Dust" 20 years ago with the same idea. No one wants it.

        The picture of a chip sitting on a finger in the article is 64 motherboards.
        Each motherboard is 1x1mm, which includes the CPU, SRAM, a PV cell for power and an LED/photodiode for I/O.
        Smaller than a relatively big grain of salt.

        I'm a little confused about the power of the thing though. They say it's similar performance to a CPU from 1990, which would be a 486.
        Except the 486 had over 1 million transistors, this has 100,000. That's more on par with a 286 from the early 80's

        • A fast 486 back in those days was 33 MHz; perhaps this runs at 330 MHz, and thus makes up for less transistor count with brute speed of execution?
          • It's still claimed to be an x86 processor though. The 100k transistor 286 had a much smaller instruction set and was only 16 bit
            The first proper "x86" was the 386, which came in at 275,000 transistors.

            It would have to be a *very* fast, very simple processor emulating x86 to be as fast as a 33MHz 486 and only require 100k transistors.
            and still run on half a bee's dick of power from a tiny PV panel.

            • It's still claimed to be an x86 processor though. The 100k transistor 286 had a much smaller instruction set and was only 16 bit The first proper "x86" was the 386, which came in at 275,000 transistors.

              Hmmm, x86 processors [wikipedia.org] started with the 8086. It refers to a fundamental architecture and instruction set. I think your arbitrary declaration of 386 as the first "proper" x86 is misguided.

              • Even so, an x86 from 1990 was a 486 with a million transistors.

                An 8086 does about 0.1 mips per mhz, while a 486 does around 0.6. You'd need to run an 8086 at 300MHz is compete with a 50MHz 486. Probably much faster if you're using 32bit math. Even faster again to compete with the memory bandwidth difference.

                • The 386 was still in heavy use in 1990; the 486 had just been released. I would wager there were at least 10X the number of 386 PCs in use in 1990 as there were 486 PCs. The 386 had around 275K transistors (fits with this story), and would do about 11 MIPS at 33 MHz, so if you clock that up to 300 MHz you're around 100 MIPS. Not too shabby!
        • Except the 486 had over 1 million transistors, this has 100,000. That's more on par with a 286 from the early 80's

          Number of transistors is not the only factor determining the performance of a CPU. The switching speed of a transistor is a determining factor as well, and the process size that is fabbed nowadays is in the few tens of nm in size (10-16 nm), while it was about 500 nm in mid 1990s. This implies much lower capacitances and therefore, much higher switching speed.

    I know, I know, we don't read the article. And this one was crap too. Buzzword noise.

    But the block diagram was included, at least, and that's fascinating. Unlike Intel and their little chip, IBM has actually thought about the practicality of using the thing. It comes with an integrated solar cell and an integrated photo-diode communications array for both transmission and receipt of data. It also includes some SRAM. No mention of how many bytes, no mention of data throughput from the array, no mention of actual power consumption (and accompanying heat dissipation).

    All coverage appears to be essentially content-free crap designed to pump IBM's stock price.

    Maybe somebody can figure out what to do with it. It's going to be difficult since all I/O requires line of sight.
