Amazon drafts blueprints for its own home router, IoT gateway ARM chips

Web bazaar's SoC subsidiary expands networking line

Amazon is readying its own ARM-compatible processors to power home routers, Wi-Fi hotspots, and network-attached storage boxes.

The Alpine system-on-chips were designed by Annapurna Labs, a fabless biz founded in 2011. It is based in San Jose, California, and Israel, and was bought by Amazon in early 2015 for about $350m.

The Alpine processor cores use licensed ARM blueprints: they run 32-bit ARMv7 or 64-bit ARMv8 code, so they can take advantage of the toolchains, apps, and things like OpenWRT and open-source hypervisors, in the ARM ecosystem.

Annapurna's chips, which seem to be dual or quad-core Cortex-A15-powered, are already in use in some storage products – for example, the Gigabyte D120-S3G box o' disks, the Netgear ReadyNAS 214, and some gear from QNAP and Synology. Software support for the SoCs is included in the Linux and FreeBSD kernels.

What appears to be new here is that Annapurna is expanding its Alpine range out to routers, and Internet-of-Things gateways and hubs, using beefier Cortex-A-family cores. It boasts support for up to 10G Ethernet, PCIe gen-3 interfaces, DDR4 RAM, and so on; all the ingredients for streaming high-def video from hard drives and the internet.

And it seems the Amazon subsidiary is now touting these networking-focused designs to hardware factories, and the likes of Netgear and other consumer-grade equipment businesses. We're told "a hardware development kit (HDK) for Alpine-based designs, which includes schematics files, layout files, thermal guidelines, and a bill of material (BoM)," is available if you want to use one of these chips.

Just don't expect them to be on sale among the bargains on just yet. ®

  • Stolen university credentials up for sale by Russian crooks, FBI warns
    Forget dark-web souks, thousands of these are already being traded on public bazaars

    Russian crooks are selling network credentials and virtual private network access for a "multitude" of US universities and colleges on criminal marketplaces, according to the FBI.

    According to a warning issued on Thursday, these stolen credentials sell for thousands of dollars on both dark web and public internet forums, and could lead to subsequent cyberattacks against individual employees or the schools themselves.

    "The exposure of usernames and passwords can lead to brute force credential stuffing computer network attacks, whereby attackers attempt logins across various internet sites or exploit them for subsequent cyber attacks as criminal actors take advantage of users recycling the same credentials across multiple accounts, internet sites, and services," the Feds' alert [PDF] said.

  • Big Tech loves talking up privacy – while trying to kill privacy legislation
    Study claims Amazon, Apple, Google, Meta, Microsoft work to derail data rules

    Amazon, Apple, Google, Meta, and Microsoft often support privacy in public statements, but behind the scenes they've been working through some common organizations to weaken or kill privacy legislation in US states.

    That's according to a report this week from news non-profit The Markup, which said the corporations hire lobbyists from the same few groups and law firms to defang or drown state privacy bills.

    The report examined 31 states when state legislatures were considering privacy legislation and identified 445 lobbyists and lobbying firms working on behalf of Amazon, Apple, Google, Meta, and Microsoft, along with industry groups like TechNet and the State Privacy and Security Coalition.

  • SEC probes Musk for not properly disclosing Twitter stake
    Meanwhile, social network's board rejects resignation of one its directors

    America's financial watchdog is investigating whether Elon Musk adequately disclosed his purchase of Twitter shares last month, just as his bid to take over the social media company hangs in the balance. 

    A letter [PDF] from the SEC addressed to the tech billionaire said he "[did] not appear" to have filed the proper form detailing his 9.2 percent stake in Twitter "required 10 days from the date of acquisition," and asked him to provide more information. Musk's shares made him one of Twitter's largest shareholders. The letter is dated April 4, and was shared this week by the regulator.

    Musk quickly moved to try and buy the whole company outright in a deal initially worth over $44 billion. Musk sold a chunk of his shares in Tesla worth $8.4 billion and bagged another $7.14 billion from investors to help finance the $21 billion he promised to put forward for the deal. The remaining $25.5 billion bill was secured via debt financing by Morgan Stanley, Bank of America, Barclays, and others. But the takeover is not going smoothly.
