Embedded Podcast

Dmitry Grinberg joined Elecia( @logicalelegance ) and Chris( @stoneymonster ) to talk about running Linux on small microprocessors (physically small and/or 4-bit).

The transcript( embedded.fm/transcripts/506 ) from the show is also available now!

You're invited to share your favorite quotes.

Thank you to Mouser Electronics for sponsoring us!

Did you know that the 'NT' in Windows NT stood for "Nine Ten"?

The intended core platform for the OS was the then-expected Intel i910 RISC processor, which was to be the rebranded moniker for the i860 that can be found in the wild.

It never came to be due to the i860s terrible handling of context switching -- a capability that a CPU for a multitasking, multiuser workstation OS must be able to do _very_efficiently_. The i860 wasn't.

Inside SiFive’s P550 Microarchitecture
🔗 old.chipsandcheese.com/2025/01

"The P550 is a 3-wide out-of-order core with a 13 stage pipeline. Out-of-order execution lets the core move past a stalled instruction to extract instruction level parallelism. It’s critical for achieving high performance because cache and memory latency can be significant limiters for modern CPUs."

Chips and Cheese · Inside SiFive’s P550 MicroarchitectureRISC-V is a relatively young and open source instruction set. So far, it has gained traction in microcontrollers and academic applications. For example, Nvidia replaced the Falcon microcontrollers …

RISC-V Vector Extension overview
🔗 0x80.pl/notesen/2024-11-09-ris

"The goal of this text is to provide an overview of RISC-V Vector extension (RVV), and compare — when applicable — with widespread SIMD vector instruction sets: SSE, AVX, AVX-512, ARM Neon and SVE.
[…]
The vector extension is quite a huge addition. It adds 302 instructions plus four highly configurable load & store operations."

I'd be much more excited if they'd be working on Risc-V stuff, but the collaboration between Fujitsu and Supermicro on new datacenter servers based on an ARM processor is nonetheless interesting. They underline how ARM CPUs and liquid cooling could make datacenters and AI freny more sustainable, and it could be true. At the very least, it couldn't - per se - make things worse.

But I'm more curious about the impact that similar announcements can have on the datacenter processors architectures market. Yes, x86 still rules and will rule for a while: the barrier to entry is quite high. But Intel is quite meh at the moment, AMD cannot do everything and some companies are eager to make some unsafe bet.

And Fujitsu has already proved that can do things a bit differently than the rest of the market. Like years ago, pushing quantum annealing when it was un-cool and everybody wanted to see real quantum computers.

So well, who knows. ARM in the datacenter isn't exactly new but it's still interesting. Now mates, let's work on more Risc-V stuff.
