mircea_popescu: they did this dumb shit whereby passing was done by shared registers ; every process or w/e could see 8 proper and 8 shared or such.
asciilifeform: the thing being indexed, gets populated ( or not ) exactly like, e.g., ipv4, or the holes in your pci bus, etc
asciilifeform: the index into these is a register. having some immutable width.
mircea_popescu: not the register width.
mircea_popescu: asciilifeform at issue is the count of "registger windows" that can be implemented.
asciilifeform: the word is this-wide.
asciilifeform: mircea_popescu: you can't have infinitely elastic registers. there's N bits , physically.
mircea_popescu: leaving aside how "our idea of scalable is to define a number up to 32 and then you can go from 3 to 32 and this is now scaling" hurr.
asciilifeform: mircea_popescu: it was a pretty ordinary thing in '80s
mircea_popescu: asciilifeform ftr, the "register window" spark thing seems the height of idiocy, but what do i know.
mircea_popescu: the usg not holding up to its side of any bargain it ever made -- also surprise. to some people.
asciilifeform: ( largely because they historically were able to externalize the cost. )
asciilifeform: it apparently is a surprise to some people.
mircea_popescu: asciilifeform so the cost will be epsilon, 0 from real estate and epsilon from heat.
mircea_popescu: the design of any general purpose item is above, there's no exceptions.
asciilifeform: ( it can lower thermal output, so still makes sense sometimes to have empty. )
mircea_popescu: so the cost will be 0, this is correct.
asciilifeform: correct. but the answers to these depend SEVERELY on the substrate. for instance, if your thing lives in a fpga, not filling it up doesn't make it cycle any faster. so you want to actually use the available gates, if they can be used productively
mircea_popescu: (what is the total cost of this item ? what percentage of that is this new addition ? what is the output of this item ? what percentage of that would the new addition produce ? make these two rations equal, you're done adding parts.)
mircea_popescu: but the decision of whether to have or not have barrel shifter is strictly carried on the cost of it.
asciilifeform: ( or, on the extreme end of things, not having arithmetic other than add-one. as scheme chip did. )
asciilifeform: or the cost of not having a barrel shifter.
asciilifeform: the basic tradeoff is, the fewer the moving parts in cpu, the more constrained is the horse by the switching elements' speed.
mircea_popescu: that's the design flow. automobile, therefore powerplant, therefore ice.
mircea_popescu: car gets internal combustion engine NOT because "the needs of the buyer", but because it needs a power plant and that's the better powerplant available. the needs oif the buyer are welcome to adapt.
asciilifeform: there are several known schemes for this.
mircea_popescu: asciilifeform design does not proceed towards requirement.
asciilifeform: and answer very very depends on what is required in terms of horse
mircea_popescu: you know, the basis of design and documentation.
mircea_popescu: for my own curiosity, what's the state of the art re "MINIMAL cpu design" ? ie, the theory of how many instructions mustg be in a set and why and per-instruction justification and everything ? ☟︎
asciilifeform: and the ones in cn also iirc.
asciilifeform: it's what the ru elbrus folx ripped off for elbrus.
mircea_popescu: yep! and all the same things, too. "community", there;'s also a "sparc-climate science".
asciilifeform: at any rate the published opensparc fpga thing actually worx
asciilifeform: probably 9000 things
mircea_popescu: so indeed, nuked very well. they even invented "other things" to be it instead of it.
mircea_popescu: as per google : "SPARC is a global coalition committed to making Open the default for research and education." and Sparc - Wikipedia https://en.wikipedia.org/wiki/Sparc Sparc is an exclusive import distributor for the Philippine market.
asciilifeform: major objective of the usg.oracle acquisition, was to nuke it.
jhvh1: pete_dushenski: The operation succeeded.
pete_dushenski: !~ later tell BingoBoingo working on blackzilla-infant photo. in the meantime, please enjoy these other lawnmower solutions http://www.caranddriver.com/comparisons/mobility-scooters-comparison-test-whill-vs-pride-vs-golden-tech-comparison-test
asciilifeform: sparc fit all of the wish list conditions ( incl. being multi source ) when it was alive. today afaik dead.
mircea_popescu: powerpc was an intel tyhing i thought
pete_dushenski: west will split off in my lifetime, probably into two pieces. prairies will have stand your ground, west coast will have "he's entitled to his opinion"
asciilifeform: which i'm quite confident leaves : the empty set.
asciilifeform: briefly revisiting the cpu thing, incidentally i forgot a 7) not ppc
asciilifeform: iirc they have the opposite
pete_dushenski: it's official mouthpiece of Truth
mircea_popescu: i see it in the same samizdat as always.
mircea_popescu: i don't see this in pravda.
pete_dushenski: the difference being, pravda didn't used to publish post-interrogation bitching by defendent. now... does.
mircea_popescu: he's exactly right, at that. precisely the sort of thing that happenbs in soviet unions.\
pete_dushenski: like, no shit dude, wtf kinda revelation is this. another quiet #t reader, apparently.
pete_dushenski: "The whole experience was horrifying," says Adam Lackman, founder of TVAddons and defendant in a copyright infringement lawsuit launched by the television giants. "It felt like the kind of thing you would have expected to have happened in the Soviet Union." << my fav quote from piece.
pete_dushenski: asciilifeform: aha. actually saw that already this morning.
mircea_popescu: how are these different ?
asciilifeform: if anyone has any knowledge, even thirdhand, of such a thing existing -- plz to post.
asciilifeform: summary : asciilifeform is looking for a 1) 32 ( or greater ) bitness cpu 2) that is able to execute code WHOLLY from external bus ( a la 1980s ), incl from rom 3) not ARM 4) in production
hanbot: mod6 : coupla more typos, if you care, http://wotpaste.cascadianhacker.com/pastes/jdZ6j/?raw=true
mircea_popescu: by mass, the lenin world was built out of the fat of the idiots who lived in old shithouse, wrung out through their skin pores.
a111: Logged on 2017-01-26 14:44 asciilifeform: because unfortunately lenin was right when he wrote 'we build new world from the planks of the old shithouse we blew up, not from imported brick'
asciilifeform: asciilifeform however habitually collects and referments the aborted foeti of items which nearly existed, to try an' grow item that exists. because no other materials available.
mircea_popescu: it seemed like it may exist ; upon examination it turns out ignis fatuus
mircea_popescu: so the arch is NOT actually documented.
asciilifeform: which in practice are needed to do anything particularly useful.
asciilifeform: for the debug extensions.
mircea_popescu: for the chip ?
asciilifeform: can make board quickly. but nowhere does -- afaik! -- the full doc exist publicly.
asciilifeform: well yes, so asciilifeform picked up a classic devboard to investigate
mircea_popescu: in the process discovering that a) they diverge from the spec and b) in no particular or ennumerable way.
asciilifeform: that was the contemplated item
mircea_popescu: unless we make an actual board for the extant superh items
asciilifeform: reporting today that result of this is still empty.
asciilifeform: for clarity : asciilifeform ain't inluvv with superH. but he ~does~ search for a cpu where 1) respectable (say, even trb-capable) horse 2) no internal flash rom 3) not ARM
mircea_popescu: so it's basically "this piece of flotsam i once found which for a time light up when you said boo".
asciilifeform: ( other than a pdf where 'flip the dip switches like-so, click in winblowz like-so' )
asciilifeform: it exists in everybody's 1990s game console, stereo, vcr, etc. and now also in that fpga item.
mircea_popescu: in what sense does this item exist then ?
asciilifeform: also typical.
mircea_popescu: is it documented by the japs at least ?
asciilifeform: anyway this isn't half the grief : if it were just a matter of flashing, i could flash via crocodiles, applied externally. but you need the debugger to singlestep.
asciilifeform: apparently they flashed it in from winblowz.
mircea_popescu: but didn;'t the dorks need to use some kind of debugger to get it to boot linux anything ?
mircea_popescu: how the fuck is this possible ?
asciilifeform: this doesn't change the fact that the only other non-internalflashed serious-horsepower chips are ARMs.
a111: Logged on 2017-07-31 17:07 asciilifeform: the sh2, which is still massively made, beats the mips micros available on open market in ability to run from external rom
asciilifeform: in very very other lulz, asciilifeform actually got hold of a superH ( http://btcbase.org/log/2017-07-31#1691143 see also ) dev board, sh7216. mega-disappoint : ZERO linux support for the on-board debugger. which one actually NEEDS to do anything whatsoever with the thing. ☝︎
mircea_popescu: in other "crowdsourcing", http://publications.newberry.org/dig/rc-transcribe/index (chicago library looking for volunteers to type old english/vernacular latin texts)
mircea_popescu: http://www.laweekly.com/arts/the-highlander-taught-me-how-to-sword-fight-7558697 << actually apparently they have the same dumbass on the west coast, too. http://archive.razorcake.org/site/spaw/uploads/files/Liz_O_b.jpg ☟︎
mircea_popescu: i thought this was english.
asciilifeform: it was in the mass of us tv asciilifeform saw in '90s when he still had a tv, to suck in the language
mircea_popescu: tales from the crypt : the new generation or how did it go
phf: oh, yeah, the guy from the tv show. i think i might've watched it back in russia, along sliders and quantum leap and such
mircea_popescu: ~only thing that can help with local carrier is if so and so "businessman" calls. otherwise...
mircea_popescu: adrian paul! there we go. dumbass name to boot.
phf: maybe it helps with a local carrier? "i was at this party with such and such" works on people who don't usually go to parties with such and such
mircea_popescu: i dunno, they were figuring it's gonna help their "careers", as if 200 dollar a show tv extras in intl markets have fucking careers or somethign.
mircea_popescu: and all the ~OLD~ ro tv hookers were crowding him, it was fucking hysterical to watch.
mircea_popescu: so i was once at a party, i dun recall teh details, but that dude, adrian whatever, was there.
phf: yeah! i rewatched it recently on a plane ride, it's incredibly bad in the way only 80s movies can be
mircea_popescu: the thing with the beheadings ?
