Forth, za one sa razlčitim rasporedom vijuga...

"In my experience: Never ask a forth fan if something is possible. You'll get only one answer: yes, of course it is. "

Momci, (Vojče, Macola, Dragan), ko je "krio" ovo od nas sve ove godine ?

Naravno da ima, CUDA Forth na primer:
https://github.com/michelp/cudafor

Ili ovako nešto iz Google grupe:

IMHO, the most interesting development towards a Forth on the GPU is SPIR-
V, the virtual machine for Vulcan (and OpenCL). Conceptually, this
should be an umbilical Forth, so you write Forth code, which gets
translated into SPIR-V, and you can let it run as shader or compute core.

Zanimljivo, nisam skorije radio sa nekim DAC-kićem koji ima ovavku inicialnu preciznost tj kada DAC dobije instrukciju da na primer postavi 110mV pa zatim relativno merenje i komanda za 120 mV i instrument pokaže ovo sa fotke a pri tome taj DAK-ić dolazi za nožice kontrolera i ima setling-time reda 2ns i sve se pokrece kroz FORTH tj u ovom konkretnom slučaju TAQOZ Forth na 8-core Propeller 2 kontroleru!

Imam problema sa brzinom opreme, najbrži FTDI 232R USB interface koji imam radi do 3MBaud-a asinhronu serisku komunikaciju, inače Propeller 2 radi do nekih 20MBaud : ) ... Inače ima auto-speed detekciju, tj ovaj kontroler se ne buni ni za jednu brzinu, šta imaš i kolko možes ti teraj ...

BTW: Da ne nabrajam šta sve ima u ovom TAQOZ i kakve sve podrške, samo kada sam video da je neko u tu verziju uključio i "drajver" za Si5351 Clock Generator, pomislio sam da se neko šali samnom!?

A ako hoćete baš tačno da nabrajam šta sve ima u TAQOZ Reloaded V2.5 za Paralax Propeller 2, to se u FORTH kaže "WORDS" pa gledajte

Interaktivni assembler, VGA podrška, PS/2, uSD kartice, bruka ... u oko 60kB interaktivnog Forth-a u 8-paralelnom radu ...

[Macola]

Obzirom da P2 ima 64 IO pinova, i neka bude da upotrebimo 10 za uSD, konzolu, neku memoriju, ostaje još 54 slobodnih pinova, od kojih SVAKI i svi odjednom, mogu biti: adc, dac, IO, komparatori, digitalna logika i još gomilu funkcija golih smart pinova, a bez bitnog angažovanja jezgara.

P2 ima jako moćan hardver smart pinova, plus što ima 8 jezgara koji praktično rade istovremeno (samo prvih nekoliko taktova treba da se ulanči bafer i posle su istovremeno angažovana).

Sam Forth zahteva drugačiji način razmišljanja od ostalih jezika i apsolutna je greška da pokušate neki svoj kod (npr C i td...) da "preradite" na Forth.

Dobićete daleko lošije performanse od maksimalnog rezultata. Treba drugačije razmišljati iz korena.

Kod Forth je dobro iscepkati masivniji kod na više sitnih reči, koje ograničeno u jednom mahu koriste stek, a na taj način se maksimalno izbegava pravljenje i upotreba varijabli i štedi se jako na vremenu izvršenja...

Takođe, za razliku od mase ostalih jezika, ovde možete imati gomilu povratnih vrednosti iz "funkcije", tj. iz REČI.
Broj povratnih vrednosti je praktično ograničen samo dubinom steka.

Uspeo sam da spojim minimalni Forth koji sam postavio ovde sa Qt-om.

Vrlo interesatna priča, prvo što to odprilike da to niko nije probao niti koristio (osim jednog rusa, administrator nekog foruma : ), drugo što mi je trebalo od same ideje i pomisli da tako nešto uradim i poteram neki osnovni koncept odprilike manje od jednog dana, treće radi mnogo dobro, četvrto kako se to "bezobrazno dobro" integriše i kako se prelepo skače iz konteksta u kontekst preko stack-a, peto Qt (C/C++) je postao napokon interaktivan kada mu se ubaci Forth interpreter i napokon mogu da izvršim sekvencu komanti poput ove koja se zove "skok" koja hvata nekoliko Qt kontrola i "klikne ih" u razmaku od jedne sekunde, da mi preskoči tamo neke korake da ne moram ja stalno to da klikćem ručno ...

Code:

": skok fl click 1000 msleep gotit click 1000 msleep usb click ;\n"
