The very neat part about firmForth is that if you compile the firmForth JIT with cparser (libfirm compiler), it can inline C functions into the JITted code.

Yeah, code-morphing/hardware JIT is extra weird (and probably why Nvidia's Project Denver kinda tanked—turns out, that doesn't work too great for smartphone apps). One thing I've thought about is having a code-morphing C

Eh, the Transmeta Crusoe (first gen) processors had pretty decent performance compared to Pentium M at much lower TDP. The Transmeta Efficeon (second gen) had performance comparable to bigger processors but had some thermal issues that hind

Even if the details are a bit… inscrutable, I do like that figuring out the structure of this interpreter is quite easy as it's all on one page and easy to see all the “moving parts”. It perhaps looks a bit scary, but it is, IMO, much

As impressive as that is, I doubt there's much room for RISC-V in Cortex-A's target market (phones, smart TVs, etc etc). I explicitly mentioned Cortex-M.

66 years from the invention of the airplane, we landed a man on the moon. 50 years later, we regularly fly from New York to Tokyo in 3 hours via supersonic upper-atmosphere aircr—wait a second, that's not how that turned out at all. Sa

ARM Cortex-M is quite likely much smaller and more power efficient than RISC-V will be for the foreseeable future. If RISC-V is going to go anywhere, it's going to have to start with hobbyists and RaspPi-like devices.

SQLite is pretty fast actually. More problematic is that this uses Electron. Loading a tiny 200-line CSV file took 120MB for me lol

Because 2MB of MRAM for $43¹ is not exactly game-changing.² 3D-XPoint is more like a much faster SSD than real NVRAM. Everspin and other true NVRAM companies are trying very hard and making huge strides, but scaling density up to expected m

For better or worse, I wrote https://github.com/alpha123/cpplib which is actually used in a commercial product. The C preprocessor can be remarkably useful for metaprogramming.

I thought it was just the PowerPC one (which had a different, Mach-based kernel), but it turns out¹ that it has had some sort of SMP support since 2.11 in 1993. 1. http://www.edm2.com/0509/smp2.html

A new kernel with SMP support suggests they have at least some source access.

OTOH, if you're a Prolog programmer and you write a type checker, you rather quickly realize what's going on ;-)

What would be really interesting if AMD CPUs and GPUs both support their Infinity Fabric concept. Heterogeneous systems with high-performance direct memory access is a huge deal.

Pretty much. Mainframes have been very I/O oriented from the start. Channel I/O (more or less DMA) with dedicated channel programs and processors can be very high-throughput.

Windows does this very aggressively. It's built in to the I/O subsystem, actually, and (IIRC—it's been a bit since I've messed with this) IOCP calls execute immediately (on the same thread, avoiding any context switches)

It's instantaneous for large projects. Literally I've compiled fairly large Delphi projects in the time it takes a Python interpreter to start.

Why would someone trying to learn Rust be interested in a web framework? I think they ought to learn how Rust works first, or they'll just be more confused.
