Lightweight wireless AR Smart Viewer reference design is powered by Snapdragon XR2 platform

Snapdragon XR2 wireless AR smart viewer reference design

Qualcomm unveiled a new Wireless AR Smart Viewer Reference Design powered by the Snapdragon XR2 platform last week with very few details, but the company has now demonstrated the system to some members of the press, so let’s have a closer look. The reference design aims to provide a similar level of performance as a headset connected to PC or premium smartphone, but with some of the processing offloaded to the Snapdragon XR2 processor, thereby eliminating the need for a cord while still achieving lag-free experiences in combination with the Qualcomm FastConnect 6900 WiFi 6 and Bluetooth 5.3 solution. It is supposed to offer a 40% thinner profile and a more balanced weight distribution than the earlier Snapdragon XR1 smart glasses reference design.   Wireless AR Smart Viewer reference design specifications: SoC – Qualcomm Snapdragon XR2 with Octa-core processor with 1x Kryo Gold prime @ 2.84 GHz + 3x Kryo […]

Linux 5.18 release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 5.18 release arm risc-v mips

Linux 5.18 is out! Linus Torvalds has just announced the release on lkml: No unexpected nasty surprises this last week, so here we go with the 5.18 release right on schedule. That obviously means that the merge window for 5.19 will open tomorrow, and I already have a few pull requests pending. Thank you everybody. I’d still like people to run boring old plain 5.18 just to check, before we start with the excitement of all the new features for the merge window. The full shortlog for the last week is below, and nothing really odd stands out. The diffstat looks a bit funny – unusually we have parsic architecture patches being a big part of it due to some last-minute cache flushing fixes, but that is probably more indicative of everything else being pretty small. So outside of the parisc fixes, there’s random driver updates (mellanox mlx5 stands out, […]

Qualcomm Wi-Fi 7 Networking Pro Series SoCs support up to 33 Gbps PHY rate, up to 2,000 clients

Qualcomm Wi-Fi 7 networking pro

Qualcomm has announced the Wi-Fi 7 capable Qualcomm Networking Pro Series Gen 3 family designed for routers and access points with a PHY rate up to 33 Gbps with the quad-band 16-stream Networking Pro 1620 platform and offers some competition to the recently announced Broadcom WiFi 7 access point chips. The company will also offer the tri-band 12-stream Networking Pro 1220 with up to 21.6 Gbps aggregated link rate, the quad-band 8-stream Networking Pro 820 capable of 16.5 Gbps PHY rate, and at the low-end of the scale, the Networking Pro 620 limited to 10.8 Gbps with three bands and six streams. Qualcomm Networking Pro 1620 (IPQ9574) platform specifications: CPU – Quad-core Arm Cortex-A73 @ 2.2 GHz System Memory – DDR3L, DDR4 16/32-bit Storage –  eMMC, NAND, Serial NOR, SD/eMMC Networking Wired – 6 Port Integrated Ethernet Switch 4 x 2.5 GbE + 5 GbE + 10 GbE Wireless Wi-Fi […]

Linux 5.17 release – Main changes, Arm, RISC-V, and MIPS architectures

Linux 5.17 changelog

Linus Torvalds has just released Linux 5.17: So we had an extra week of at the end of this release cycle, and I’m happy to report that it was very calm indeed. We could probably have skipped it with not a lot of downside, but we did get a few last-minute reverts and fixes in and avoid some brown-paper bugs that would otherwise have been stable fodder, so it’s all good. And that calm last week can very much be seen from the appended shortlog – there really aren’t a lot of commits in here, and it’s all pretty small. Most of it is in drivers (net, usb, drm), with some core networking, and some tooling updates too. It really is small enough that you can just scroll through the details below, and the one-liner summaries will give a good flavor of what happened last week. Of course, this means […]

UCIe (Universal Chiplet Interconnect Express) open standard for Chiplets with heterogeneous chips

UCIe Open Chiplet platform-on-a-package

We first heard about Chiplet, chips that gather IP or chips from different vendors into a single chip, in 2020 with the now-defunct zGlue’s Open Chiplet Initiative, but the term recently came back to the forefront last month with Intel’s investment into the “Open Chiplet Platform” that aims to offer a modular approach to chip design through chiplets with each block/chiplet customized for a particular function. It turns out there’s now an official standard called the Universal Chiplet Interconnect Express (UCIe) whose specification defines the interconnect between chiplets within a package, and not only backed by Intel, but also AMD, Arm, ASE, Google Cloud, Meta, Microsoft, Qualcomm, Samsung, and TSMC. UCIe defines the Physical Layer (Die-to-Die I/O) and protocols to be used for the chiplet interfaces, currently PCIe and CXL (Compute Express Link), but more protocols will be added to the specification in the future. The goal is to provide […]

Snapdragon X70 5G modem leverages “AI” to reach 10 Gbps

Snapdragon X70 5G AI modem

Qualcomm has announced their latest 5G modem with the Snapdragon X70 that is said to “uses the power of AI” to enable 5G speeds up to 10 Gbps, wider coverage, low latency, and higher power efficiency. The company explains the Qualcomm 5G AI Suite enables AI-powered optimizations of sub-6 GHz and mmWave 5G links on the Snapdragon X70 through various techniques: AI-based channel-state feedback and dynamic optimization AI-based mmWave beam management for superior mobility and coverage robustness AI-based network selection for superior mobility and link robustness AI-based adaptive antenna tuning for up to 30% improved context detection for higher average speeds and coverage That’s about all the details we have about the “artificial intelligence” part, and I’m not convinced neural networks are actually used here. For reference, the previous generation Snapdragon X65 was also sold as a 10Gbps 5G modem, but maybe Snapdragon X70 can achieve high speeds more reliably. […]

Qualcomm announces FastConnect 7800 WiFi 7 & Bluetooth 5.3 solution

Qualcomm FastConnect 7800 WiFi 7 chip highlights

Qualcomm has just announced the FastConnect 7800 WiFi 7 and Bluetooth 5.3 subsystem for smartphones, laptops, and virtual reality headsets promising peak speeds of 5.8 Gbps as well as sub-2 millisecond latency. We first detailed some of WiFi 7 features such as up to 40 Gbps link, and real-time capabilities when MediaTek showcased its future 802.11be compliant Filogic processor to customers, so it should be no surprise that Qualcomm had been working on its own solution, and announced it at Mobile World Congress 2022.
