Embedded Systems

Linus Torvalds on a "debug session from hell" in the Linux Intel Xe GPU driver: AI did much of the grunt work and "enormously helped" but repeatedly concluded the bug was impossible. A nice example of AI as a tool, not a replacement for engineering.

A 30-year-old article on finite state machines in Forth that still feels relevant to embedded software today. The neat idea: turn the state-transition table itself into executable structure, rather than a pile of conditionals.

RT @vivekgalatage: After the beginner-friendly roadmap from the previous post, here comes a comprehensive ebook: Embedded Systems - Shape The World.

RT @controlpaths: Today is (also) about HW

Is it time to revisit microkernels? With today's hardware and growing emphasis on safety and isolation, are the classic arguments against microkernels still valid? Worth a read for anyone working on embedded or safety-critical systems.

The SDK is part of your power budget. Same ESP32-C6. Same workload. Different power consumption. A nice reminder that firmware architecture matters just as much as hardware when optimising battery-powered designs.

Inside BMW’s latest infotainment platform: Snapdragon SA8155P, automotive Ethernet, APIX, safety MCU and more. An excellent hardware teardown for anyone interested in embedded systems and automotive electronics.

Labelled data is scarce for embedded vision. SemSim uses semantic similarity to improve semi-supervised image segmentation. An interesting idea with applications beyond medical imaging. #EmbeddedAI #ComputerVision

Running DOOM is cool. Building the CPU that runs it is cooler. This write-up follows the journey from designing a custom RISC-V processor to FPGA implementation and using DOOM to validate the design. Excellent hardware/software co-design read.

RT @vivekgalatage: Embedded Software Engineering 101

Origami meets electronics: researchers created conductive circuit traces by folding and cutting a liquid-metal-impregnated paper-like material. An intriguing approach for rapid prototyping, STEM education, and interactive paper devices.

EMiX extends FPGA emulation beyond the limits of a single board by partitioning RISC-V SoCs across multiple interconnected FPGAs. The authors demonstrate a Linux-capable 64-core system spanning 8 FPGAs and plan to open-source the framework. #RISCV #FPGA

A remarkable piece of embedded systems history: in 2001, a tiny web server was embedded in a preserved housefly. More than a technical feat, it’s a thought-provoking exploration of technology, media art, and ethics.

How do breakpoints even work?

Why malloc is doing more than I asked for

If you're writing embedded firmware in C, this free book deserves a place in your library. Modern C by Jens Gustedt i not an embedded book but it'll make you a better embedded developer. Free PDF:

From spinning platters to firmware internals: a fascinating look at how hard drives really work. If you're into embedded systems, firmware analysis, or hardware hacking, this is worth your time #embedded #firmware #JTAG by @Grimdoomer

NASA still maintains some of the Voyager spacecraft code in a 1970s-era programming language that almost nobody on Earth fully understands anymore, and the handful of engineers who do are now in their 80s

Want to understand what really happens inside a scientific calculator? This 10-part series covers numerical methods, a custom CPU, microcode, BCD arithmetic, FPGA implementation, PCB design, and verification. A fantastic engineering deep dive.
