Alibaba XuanTie C950 – A powerful, RVA23-compliant 64-bit RISC-V core for Edge AI computing

Alibaba has introduced the XuanTie C950 high-performance, 64-bit multi-core CPU IP with an out-of-order superscalar microarchitecture, RVA23 profile compliant, and support for “all optional extensions” such as Vector Crypto, Zacas, and Zama16. The company also says the XuanTie C950 supports the proprietary XuanTie AME (Attached Matrix Extension) ISA and supports integration with the company’s XuanTie TPE (Tensor Processing Engine) IP. The new 64-bit RISC-V core will be found in SoCs with up to eight cores per cluster, targeting high-performance applications, such as cloud computing, edge computing, and AI computing. XuanTie C950 specifications: Architecture – RVA23 Profile Up to 8x cores...

Book Explores ELBE Workflows for Embedded Linux Systems

A new book titled Building Embedded Systems with Raspberry Pi, Linux, and ELBE by Krishna Pattabiraman describes approaches for developing reproducible Debian-based embedded Linux systems using the ELBE build environment. The content focuses on structured system design, image generation, and long-term maintainability for Raspberry Pi–based platforms. The content targets developers working on production-oriented systems, with […]

Using FireWire on a Raspberry Pi

After learning Apple killed off FireWire (IEEE 1394) support in macOS 26 Tahoe, I started looking at alternatives for old FireWire equipment like hard drives, DV cameras, and A/V gear.

I own an old Canon GL1 camera, with a 'DV' port. I could plug that into an old Mac (like the dual G4 MDD above) with FireWire—or even a modern Mac running macOS < 26, with some dongles—and transfer digital video footage between the camera and an application like Final Cut Pro.

MINIX Mini-PC Leverages AMD Ryzen AI Max+ 395

MINIX is offering the ER939-AI, a compact mini PC built around AMD’s Ryzen AI Max+ 395 processor. The system targets high-performance desktop workloads in a small form factor, combining a 16-core CPU, integrated graphics, and an on-chip neural processing unit. The platform uses the Ryzen AI Max+ 395, a 16-core, 32-thread processor with boost frequencies […]

FOSDEM 2026 Update

Hey again RSS readers (love y’all). In this update we share what we discussed at FOSDEM (PinePhone 2, community editions, DRAM shortage), what we demoed at our stand at FOSDEM and details on the PineTime Pro. Next month will have the main community update.

BIO: The Bao I/O Coprocessor

BIO is the I/O co-processor in the Baochip-1x, a mostly open source 22nm SoC I helped design. You can read more about the Baochip-1x’s background here, or pick up an evaluation board at Crowd Supply.

In this post, I’ll talk about the origins of the BIO, starting by working through a detailed study of the Raspberry Pi PIO as a reference, before diving into the architecture of the BIO. I’ll then work through three programming examples of the BIO, two in assembly and one in C. If all you’re interested in is how to use the BIO, you can skip the...

The best laptop Apple ever made

Today I posted a video titled The best laptop Apple ever made, and tl;dw1 it's the 11" MacBook Air.

I acknowledge in the video my pick is slightly subjective, and I also asked a number of other YouTubers which Mac laptop they consider the best (or at least most influential). If you don't want to watch the video, I'll summarize their choices here:

Радио почти из ничего — самодельные радиодетали 1920-х годов. Резисторы

Рассматривая любительские рукодельные электронные лампы, например, [1, 2], интересно и полезно будет вспомнить и об остальных радиоэлементах, изготовлять которые ранним любителям приходилось самостоятельно и собственноручно. Кроме естественных корпусов-ящиков и контурных катушек, дросселей, трансформаторов, коллеги-предки часто были вынуждены делать и почти всё остальное — как установочные элементы — ручки, верньеры, шкалы, клеммы, включатели-переключатели, ламповые панельки, так и радиоэлементы пассивные — резисторы и конденсаторы переменные и постоянные, диоды (детекторы и выпрямители), элементы питания, в том числе и анодные (а это на минуточку — 40…80 вольт!) батареи.

Добавим — всё это предлагалось собирать обычному увлечённому гражданину, юношеству, часто школьнику и из самых чепуховых, буквально подножных...
