Eh. It's both. You don't have one without the other. SIMD is pretty much entirely extensions to base processor ISA; there might be a few architectures that have SIMD as a basic part of them (GPUs are one of them, taken to an extreme order), but for the most part you have to know which instruction set you're working with.
SIMD is basically "pack multiple data points into a single CPU register, then to another, and perform some operation on them as if you ran that op on all of the pairwise data points individually". Some ops are binary (arithmetic, bitwise, etc) and some are unary.
Some have "gates" whereby you can do a comparison, the boolean output of which is stored in a bit packed integer. Then you can run conditional instructions after that that only perform the instruction if the bit in that variable is set, creating "constant time" SIMD instructions with what amounts to branching. Really depends on the instruction set's capabilities.
AVX512 is far and away one of the most extensive extensions, with a ton of super niche instructions meant for enterprise number crunching. It has weird stuff, like swapping bytes, collating them, doing all sorts of weird manipulations. But the number of x86 CPUs that support that instruction set are small.
You can't emit code that has e.g. AVX512 and just run it on a CPU that doesn't have that extension. You get a CPU exception and it crashes the process (or, if this is in kernel/driver land, your machine).
So they're kind of tied together.
Anyway if you want to see a list of them, Intel's SIMD intrinsics site has always been really nice to browse IMO.
You're conflating "what's illegal" with "what a private entity doesn't want". I don't like it any more than you do, but the first is very clear, the second is a bit harder to "solve".
I am aware, yes. After the paste deposition via stencil, doing passives manually takes hours. I'm asking if anyone's done anything interesting with stencils for placing those.
For those of us without the cash/apartment space for a PNP, has anyone experimented with a stencil system for populating passives? Is that even a thing?
My PCB project's population time is currently 11 hours the last time I did it, from blank to tested, for one unit. The largest amount of time spent is on the resistors and capacitors - over 200 of them.
That's a stretch. This isn't a new approach to such obfuscation. Also plagiarism would mean they ripped the source material verbatim or they at least copied the methodology and intentionally used the source material's findings as their own.
It's super unbelievable they needed to. This isn't novel.
Yes of course, the transmitted audio would be mono. I meant one radio in one ear and another radio in the other ear, or if you mix them and they both play in both ears. But it sounds like they're mixed (talking over each other in a single audio stream).
This is a completely different phenomenon. Your ear/brain are tuned to rhythmic beats in the lower frequencies (footsteps). We're better at pattern recognition with the lower frequencies.
Also, our brains will encode the differences in registers to evoke emotion differently, which is often used by horror films to make a scene scarier[0]. Evolutionarily this is probably to detect screams or babies crying, a rustling bush, etc.
Speech encoding, at least per this article, has little to do with that. We don't have music encoding so much as we have pattern recognition, instinctual emotional respond to sound, etc.
Another great video about how music is perceived in animals is [1], just while we're on the topic.
Perhaps a dumb question but are they center panned (or mono, i.e. talking over each other) or is it split left ear/right ear when they come through the headset?
Not really. If the services that grant you access to your own hard disk ever go under, you lose it. You do not have access to the files. You're effectively paying for a licence to play the game for a finite amount of time, for the same (if not higher) price that physical media used to cost.
It shouldn't be the case that this is relied upon. There needs to be a cultural shift in the industry back to physical - or at least, preservable - media.
