If you're going for "turns", then I would go even further and argue that it shouldn't be represented as a float, but rather a fixed point (signed?) integer. With 0x00000000 being 0°, 0x40000000 90°, etc. You get modular

I find especially painful the tradeoff between productivity and visibility. Every minute I spend trying to advertise my project is a minute I'm not spending making it better.

If you want to spawn multiple threads, all with access to a mutex, but without putting it behind an Arc, then you can simply spawn all your threads in a std::thread::scope(||{...}). These let you pass references &'scope Mutex<..

You had me on the first three paragraphs, but the last two veer so far off course that I've no idea what you're trying to say. Mind clarifying?

Well still, why tie this kind of processing to the registers themselves? Sure having a shorthand to instantiate a queue of writes I could see, but float to fixed conversion has no place being part of a memory mapped register bank. Wouldn&#x

I find it odd the author adds all these extra semantics to their input registers, rather than keeping the FIFOs, "drain + FIFOs", "float to fixed point converting register", etc as separate components, separate from the

Well both can be true, money is only made (or lost) on market swings. It is precisely the rich who can capitalize on such swings Whereas for regular people, an upswing means nothing, whereas a downswing means job loss, mortgage rate hikes,

I've been building high-bandwidth memory streaming interfaces for HBM on VCK5000 & U280 FPGAs in my own language - "SUS". The goal is to get consistent synthesis to 450MHz such that I can use a narrower 256-bit instead of

God Roko's Basilisk is the most boring AI risk to catch the public consciousness. It's just Pascal's wager all over again, with the exact same rebuttal.

Oh hi Rachit, long time no see. I sadly didn't have time to submit something to LATTE this year as I've been spending all my time building infrastructure for SUS. I think improving the safety of hardware design is a noble goal, an

The article specifically mentions this optimization as not working with the compiler at that time, hence the need for the separate index variable. > We will edit su.c to prevent the overflow by maintaining a counter, i, and verifying it

Well really, the language _is_ the difficulty of much of hardware design, both Verilog and VHDL are languages that were designed for simulation of hardware, and not synthesis of hardware. Both languages have of similar-but-not-quite ways of

Regulation is about setting minimum standards for acceptance, not specifying exactly how. This means that if I walk into a random croissant shop and buy a croissant, I don't subsequently have 2 days of food poisoning. Arguably, healthi

Oh, I just came back from Shimla actually. I stayed in Narkanda for 2 days to do some hiking, and Shimla one day, though I didn't interact with many people there. My next stop is Kochi, hopefully things are also a little quieter there.

Oh nono, with tree-sitter, you get an untyped syntax tree. That means, you have a Cursor object to walk the tree, which creates Node objects as you traverse, that have a "kind" (name of the tree-sitter node), span, and children. (

Printing the hash of the result is a nice trick I've used a couple of times myself, but jumping through the hoops of making the inputs parametrizeable (a la env vars) is only going to make your benchmarks less reliable, not more. It co

I've used tree-sitter for generating my parsers in Rust, and just working with the untyped syntax tree it generates, and gives you error-tolerance for free. It's a bit of a setup at first tho, requiring an extra crate for the gene

For the uninitiated in AArch64, are there specific parts of it you're referring to here? Mostly what I find is that it lets you stitch common instruction combinations together, like shift + add and fancier adressing. Since the whole po
