Tech trends 2022

The year 2021 was strange, you can read more of it from A 2021 technology retrospective: Strange days indeed. But how strange will 2022 be? Here are some predictions for year 2022:

2022 preview: Will the global computer chip shortage ever end?

Industry Transforming In Ways Previously Unimaginable
https://semiengineering.com/industry-transforming-in-ways-previously-unimaginable/?cmid=3dedf05d-0284-497a-b015-daf7747872e6

As we look back over 2021, there have certainly been some surprises, but the industry continues to take everything in its stride.

2022 tech themes: A look ahead
https://www.edn.com/2022-tech-themes-a-look-ahead/

The continued COVID-19 question mark: The world quickly and dramatically changed. It hasn’t yet reverted to pre-pandemic characteristics, and it very likely never will. Sad but true, the pandemic isn’t even close to being over yet.
Deep learning’s Cambrian moment: Look at today’s participant-rich deep learning silicon and software market, spanning both training and inference.
The ongoing importance of architecture: As the number of transistors that it’s possible to cost-effectively squeeze onto a sliver of silicon continues to slow, what you build out of those transistors becomes increasingly critical.
Open source processors’ time in the sun: There is a burgeoning RISC-V movement. It’s likely a little-known fact to some of you, that a public domain instruction set for v2 and earlier versions of the Arm ISA exists. And both Sun (with OpenSPARC) and IBM (OpenPOWER) have also joined the open-source silicon movement.
The normalization of remote work (and the “Great Resignation’s” aftershocks): I suspect that, to at least a notable degree, we won’t ever completely return to the “way it was before.” In fact, I’d wager that having a taste of a work-from-home or “hybrid” employment lifestyle is one of the key factors behind the so-called “Great Resignation” that tech and broader media alike inform me is well underway.
The metaverse starts to stir: Perhaps we’ll look back at 2022 as the year when the crossing of the chasm started in earnest.
Autonomy slowly accelerates: 2021 was another year filled with fully autonomous car tests and premature “coming soon” pronouncements; 2022 will likely be the same.
Batteries get ever denser, ever more plentiful, and ever cheaper
Space travel becomes commonplace

Global semiconductor industry forecasts for 2022
https://www.digitimes.com/news/a20211229VL205.html

“2021 is the year that everyone remembered that chip mattered,” said Wired Magazine. So far 2022 seems likely to be another fruitful year for the semiconductor industry.

World Semiconductor Trade Statistics (WSTS) also has predicted that the global semiconductor market is projected to grow by 8.8 percent in 2022, to US$ 601 billion, driven by double-digit growth of the sensors and logic category. All regions and all product categories are expected to continue positive growth. Wafer foundry manufacturers sales likely to remain strong due to tight supply. 5G smartphone silicon content increase to drive demand for foundry service higher. Demand for digital transformation is here to stay, no sign of weakening for foundry service sales.

The COVID-19 pandemic accelerated digital transformation over the past two years. Work from home, virtual conference, and remote learning have driven up the demand for cloud computing, laptops, and servers, and hence the sales growth of related semiconductor products. Demands for CPU, GPU, AI accelerator (including FPGA) foundry services will remain strong in 2022 because trends such as virtual conferences, live streaming, and large capex of data centers are likely to stay. Long-term demands for customized chips in IoT, 5G infrastructure, HPC, and EV applications, like ADAS, autonomous driving, V2X, in-Vehicle Infotainment, will provide robust growth momentum for chip foundry services.

Chip crunch is not ending in 2022, as the lead time of some electronic components is stretching into 2023. Meanwhile, the increasing adoption of RISC-V open standard instruction set architecture is an important trend that can not be ignored. RISC-V market will double its size in 2022, compared to 2021, as it is attracting small and medium-size chip designers and manufacturers, especially those in China. RISC-V designs are now being used by Qualcomm, Samsung, Google, Microchip, Nvidia, and more.

The size of a standard mobile phone charger can be reduced by up to 40 percent when using GaN components or it can be designed to produce more power in the same size. GaN chargers are becoming the most popular charger technology for billions of devices, so it’s no wonder that European semiconductor giant STMicroelectronics is also excited about them.

    The Chip Shortage Leads To The Strangest Things
    https://hackaday.com/2022/08/13/the-chip-shortage-leads-to-the-strangest-things/

    The global chip shortage has not made the life of the electronic design engineer an easy one, as products have been designed around whatever parts are available rather than the first choices. This has manifested itself in some unexpected ways, including as [CNX software] investigates, products whose multiple-choice bill of materials has led to mistakes being made in manufacture.

    On the face of it, designing a PCB with two sets of footprints to accommodate more than one part choice is a clever move. But as Radxa found out with their Rock 3A single board computer, this could lead to a production mishap as some boards left the production line with a mix-and-match BoM in their USB PD circuitry which left them unable to operate from voltages above 5 V. The board has footprints for both an Injoinic and a WCH part, and the faulty boards appear to have the support components fitted for the other chip to the one on the board.

    Another consequence of supply shortage: mass production mishaps
    https://www.cnx-software.com/2022/08/10/another-consequence-of-supply-shortage-mass-production-mishaps/

    Chips may suddenly disappear from the supply chain or get really expensive due to the recurring supply shortage, companies are now designing their PCBs to support multiple chips either selecting drop-in replacements or creating multiple footprints to cater to at least one alternative part. That means one PCB and multiple bill-of-materials are needed to be more resilient to any supply disruption.

    Radxa did that on the ROCK 3A board for the USB PD circuitry with the ability to use either Injoinic IP2315 or WCH CH224D IC. Those are not pin-to-pin compatible chips, and two circuitry were made for the board requiring two BoMs as it’s not just possible to only replace IP2315 by CH224D.

    Kathrin Hille / Financial Times:
    China’s SMIC producing 7nm chips is a breakthrough but experts suggest yields are low due to lacking EUV; SMIC must now decide if it wants to mass produce 7nm

    China’s chip breakthrough poses strategic dilemma
    How much time and money will SMIC sink into producing its new semiconductor at scale?
    https://www.ft.com/content/f0ddae61-a8a3-456d-8768-971c71ccb6dd

    A breakthrough by China’s largest chipmaker revealed last month triggered a gasp of surprise among observers outside the industry. But the move by Semiconductor Manufacturing International Corporation to start shipping advanced “7 nanometre” semiconductors had only been a matter of time.

    The more interesting question now is how much time and money the company is willing to sink into producing them at scale using a method their international rivals have abandoned for a more efficient one.

    That development, expected to unfold over the coming year, will show whether Chinese chipmakers are really ready to prioritise the political cause of making their country self-sufficient over the business case of making money.

    For starters, 7nm — the marketing name for a technology process for making chips — is one generation behind the most advanced in mass production. It trails the 5nm generation of chips offered by industry leaders Taiwan Semiconductor Manufacturing Company and South Korea’s Samsung. And 7nm is just the minimum required for the high-performance computing chips that rapidly process large amounts of data in everything from servers to smartphones.

    Since hiring former TSMC veteran Liang Mong-song as its co-chief executive in 2017, SMIC has made advances in mastering manufacturing technology generations such as 16nm and 10nm.

    Analog Devices on tuonut teollisuuteen signaalin lentoaikaa mittaavan iToF-moduulin, joka pystyy mittaamaan etäisyydet +/- 3 millimetrin tarkkuudella. ADTF3175-moduuli on tarkoitettu konenäkösovelluksiin teollisuusautomaatiosta logistiikkaan, terveydenhuoltoon ja lisättyyn todellisuuteen.

    ADTF3175 tarjoaa suunnittelijoille skaalautuvan, täysin suunnitellun ja kalibroidun syvyysmittausjärjestelmän, joka voidaan integroida 3D-anturi- ja -näköjärjestelmiin. Tällä eliminoidaan tarve lisätä järjestelmiin erikoisoptiikkaa.

    China’s largest foundry is warning about slowing demand for chips as consumer electronics sales soften; TSMC had a similar comment last month.

    China’s largest foundry, Semiconductor Manufacturing International Corp. (SMIC), is nowhere close to having the same capabilities to produce cutting-edge chips as TSMC and Samsung. Still, as China dreams about being self-sufficient when it comes to chips, SMIC’s most advanced chips are basic 7nm SoCs for cryptocurrency miners, and 14nm smartphone chips. That compares to the 3nm chips that TSMC and Samsung are shipping this year.

    The datacenter industry may be starting to feel the effects of the economic slowdown, leading to further impacts on IT vendors and other suppliers, according to reports, while operators in the UK in particular are feeling the pain from rising energy costs.

    Cloud and hyperscale companies may have seemed less vulnerable to swings in the wider economy, thanks to the growing adoption of cloud services over the past decade. This was especially so during the pandemic, when many businesses were forced to upscale their use of cloud services to ensure staff could continue to work remotely.

    Optane aiheutti Intelille miljarditappiot – taas kerran
    https://etn.fi/index.php/13-news/13900-optane-aiheutti-intelille-miljarditappiot-taas-kerran

    Kesällä 2015 Intel esitteli kokonaan uuden muistitekniikan. Yhdessä Micronin kanssa kehitetty Xpoint päätyi ensin markkinoille Optane-nimellä ja nyt Intelin omalle tuotelinjojen hautausmaalle, jossa alkaa olla ahdasta.

    Micron ilmoitti keväällä 2021, että se lopettaa Xpoint-muistien valmistamisen kuluttajamarkkinoille. Yhtiö syytti kehitystyön ja valmistuksen kalleutta. Sitten Intel myi NAND-liiketoimintansa korealaiselle Hynixille. Optane-linja jäi lähinnä datakeskuskäyttöön.

    Pääjohtaja Pat Gelsingerin myötä Optane on nyt päätetty lakkauttaa. Intel ei ole julkistanut tuotelinjan aiheuttamia tappiota, mutta analyytikot puhuvat miljardeista dollareista.

    Xpointin piti olla markkina mullistava universaali muisti. Sen piti olla 1000 kertaa NAND-muisteja nopeampi ja jopa 10 kertaa DRAM-muisteja tiheämpi. Tekniikan kohtalo kuitenkin osoittaa, että mikäli piirejä ei voida valmistaa kustannustehokkaasti, mikään ominaisuus ei riitä.

    Lisäksi uusilla muistitekniikoilla on aina ollut erittäin kivinen tie päästä merkittäviin markkinaosuuksiin. Tutkimuslaitos Yole Developpementin keväisen raportin mukaan NAND ja DRAM pitivät hallussaan 96,7 prosenttia muistien markkinoista. Uusille tekniikoille kuten Xpoint, PCM, MRaM ja ReRAM lohkesi vain 0,4 prosenttia kokonaismarkkinoista. Suurten volyymien muistibisneksessä tämä tarkoittaa aina isoja tappioita.

    Intelille tämä ei ole mitään uutta. Yhtiön hautausmaalta löytyy niin mobiiliprosessoreja (StrongARM) kuin uusimpien tietojen mukaan myös erillisgrafiikkaprosessori

    Seven years later, it’s more clear than ever that the days of the headphone jack on mobile devices are numbered. Here’s how Apple was the vanguard for the death of the port — and what might be next for the connector.

    Since the iPhone 7, Apple has been slowly removing the headphone jack from its main consumer products. Although initially criticized, a number of other companies have since followed suit.

    There are still a few products in the lineup that retain a headphone jack, but recent rumors suggest that the number of Apple-designed devices with a 3.5mm port will soon dwindle again.

    Nvidian mukaan viralliselta nimeltään NVLInk-C2C kuluttaa energiaa 1,3 pikojoulea bittiä kohti. Tämä on vain viidesosa siitä energiasta, mikä bitin liikuttamiseen kuluu PCIe 5.0 -liitännän läpi. Samaan aikaan NVLinkin kaistanleveys on neljällä linjalla jopa 900 gigatavua sekunnissa eli 7-kertainen 16x PCI 5.0 -väylään verrattuna.

    Kuluttajat lakkasivat ostamasta läppäreitä

    Vuoden toinen neljännes oli ankeaa aikaa kannettavien tietokoneiden valmistajille. Strategy Analyticsin mukaan huhti-kesäkuussa myytiin globaalisti 55,5 miljoonaa kannettavaa. Määrä on 15 prosenttia pienempi kuin vuotta aikaisemmin.

    Tutkimuslaitoksen analyysin mukaan kuluttajilla ovat nyt muita painopisteitä, kuten loma, uudet vaatteet ja kodin kunnostaminen. Monet varovat uusien laitteiden ostoa hintojen kallistuessa ja taantuman uhatessa. Sen sijaan yrityksissä uuteen tietotekniikkaan panostetaan ja kun myynti keskittyy yhä enemmän premium-läppäreihin, tilanne on valmistajien kannalta valoisampi.

    Sähköautojen omistajat evät pysty rentoutumaan ajaessaan, kun katse suuntautuu koko ajan akun varaustilanteeseen. Mistä löytyy seuraavalatausasema? Onko se vapaana? Kuinka tehokas se on? Sama ilmiö on tuttu älypuhelimen käyttäjille. Nyt ilmiötä on tutkittu OnePlussan teettämässä tutkimuksessa.

    Tutkimuksen mukaan akun matala varaustaso aiheuttaa monelle stressiä. Useimmat eivät poistuisi kotoa, jos puhelimen akkua on jäljellä alle 20 prosenttia. Itse asiassa lähes kolme neljästä ihmisestä (73 prosenttia) sanoo, että he eivät haluaisi lähteä kotoa, jos heillä on puhelimessa akkua jäljellä alle 20 prosenttia.
