(asciilifeform) snsabot: Logged on 2020-01-20 19:59:57 asciilifeform: ( and in fact the only properly kosher, i.e. wholly reversed, fpga on the market , is afaik still '
ice40' , which is rather small . just barely holds a useful mipslike w/ 64bit regs. )
(asciilifeform) snsabot: Logged on 2020-08-22 13:19:48 asciilifeform: ftr also there can be no question of a 500nm fpga holding anyffin like a nontrivial cpu. ( for comparison, e.g.
ice40 -- which is ~barely~ cpu-capable -- is a 40nm product. )
(asciilifeform) shinohai: I acquired
ice40, but have done only minimal verilog things with it. My sole experience with mips was getting gentoo to work w/ edgerouterlite
(trilema) a111: Logged on 2019-04-22 00:00 asciilifeform: in entirely unrelated heathen lulz : asciilifeform found an -- apparently working -- usb 'serial device' stack for
ice40 . only eats 1/3 of the LUTs in the '8k', too.

(trilema) a111: Logged on 2019-04-17 18:33 asciilifeform: meanwhile, in february, chinese
'gowin semiconductor co' cloned
ice40. but if anyone thought this means 'open spec', guess again, only worx with their 'YunYuan' closed shitware toolchain.
(trilema) a111: Logged on 2018-01-04 20:06 asciilifeform: in other 'news', it is apparently impossible to fit even ONE 4096-bit adder into an
ice40-8k ( the largest in the series )
(trilema) bvt: asciilifeform: isn't
ice40 a done thing, i.e. is there anything else to add to it?
(trilema) OriansJ: spyked: well the
iCE40 is a good starting point for now and I guess we can agree on that. You are right about not having to be portable but I prefer building a stack that can be used to defend against a Nexus Intruder program class attack.
(trilema) a111: Logged on 2019-03-17 18:55 mircea_popescu: IMO it makes no sense adopting the VM, given that apparently mips.v7 will be the republican CPU architecture on
ice40. << i very much not agree ; much too soon to standardize this.
(trilema) bvt:
http://btcbase.org/log/2019-03-17#1903106 << i also agree that it is; i don't find myself knowledgable enough to make a decision on the republican cpu architecture, but for bootstrapping using
ice40 with its limited resources a simple mips core sounded fitting.

ice40 with own hands yet. but, interestingly, when bought a 'scsi2sd' device for replacing disk in bolix box, found that author in fact used
ice40 for the job

ice40 x250 and other projects: If I get a toe hold in Qatar, they have a 'free zone' to entice foreign R&D and tech startups which permits a new company to have 100% foreign owners, 0% tax on profits, duty free import/export. But requires them to like you and what you're trying to do.

ice40 , i.e. 'tmsr cpu'.

http://btcbase.org/log/2017-08-31#1707895 -- picture an a4-sized plinth, of, e.g., 32 dimm slots. each can contain a card of sram, or alternatively of 4
ice40-8k's, or some peripheral ( e.g. nic magnetics. )
(trilema) a111: Logged on 2017-09-01 15:38 asciilifeform: in very very other noose : the vendor's vga and ps/2 kbd demo verilog for
ice40 builds and WORX
(trilema) a111: Logged on 2017-08-31 22:23 asciilifeform: since we're on subj, asciilifeform got the recently released
ice40-8k (largest in the series) going. ( there's only 1 decent dev board for the 8k, the one released by olimex ~2wks ago )
(trilema) mod6: <+asciilifeform> in very very other noose : the vendor's vga and ps/2 kbd demo verilog for
ice40 builds and WORX << cool
(trilema) a111: Logged on 2017-08-31 22:26 asciilifeform: phf: at some point ( and by this i mean when finished ffa / released 'p' ... ) i'ma have a large board made, with, say, 8
ice40-8k's, and row of dimm-holders...
(trilema) a111: Logged on 2017-08-21 21:18 asciilifeform: !~later tell spyked
http://btcbase.org/log/2017-08-21#1701446 >> on second thought, you probably could put this chore off, olimex sells a
ice40-8k (largest available) with 512k of sram glued on. and this is theoretically enough to prototype . the more pressing matter is ethernet. ( afaik nobody sells an
ice40 + ethernetmagnetics . and just as with ddr dram, answer is 'lattice wants you to use their larger fpgas, with THEIR toolchain'
(trilema) a111: Logged on 2017-08-21 12:05 spyked: ok, so to sum up; 1. get
ice40 fpga; 2. run fpga lisp machine (cadr?); work from that towards symbolics/ivory, or the other way around starting from symbolics.
(trilema) spyked: asciilifeform, was going to ask. is there particular
ice40 you're recommending? it might be a while until I get one but I looked over the list and they had various types (ultralite etc.)

ice40!!!!
(trilema) a111: Logged on 2017-08-03 23:02 asciilifeform: to add insult to injury, even BROWSING shithub ( where all of the 'open'
ice40 projects live ) no longer works on any of my graphical wwwtrons
(trilema) a111: Logged on 2017-01-16 23:36 asciilifeform: leaving entirely aside the question of whether
ice40 can in fact be made to do anything useful with the 'open' toolchain discussed earlier, or whether a toolchain that required clang, llvm, and ten other poetteringesque abortions is 'open'
(trilema) ascii_field: 'We have enough bits mapped that we can create a functional verilog model for almost all bitstreams generated by Lattice iCEcube2 for the
iCE40 HX1K-TQ144, as long as no block memories or PLLs are used. ' << wake me up when that last part changes. and when i can get this chip from ten different chinese foundries.
