I-RISC OS uhlelo olusebenzayo olwenziwe ekuqaleni yi-Acorn Computers Ltd eCambridge, eNgilandi. Yaqala ukukhishwa ngo-1987, yayenzelwe ngokukhethekile ukusebenza ku-chipset ye-ARM, i-Acorn eyayenzelwe ngasikhathi sinye ukuthi isetshenziswe kulayini wakhe omusha wama-computer ka-Archimedean.
Uhlelo lokusebenza lwe-RISC ithatha igama layo kusakhiwo esisekelwayo se-RISC (sinciphise i-set set computing).
Izinhlobo eziningi zakamuva ezizinzile sebenzisa i-ARMv3 / ARMv4 RISC PC, i-ARMv5 Iyonix, kanye namaprosesa, i-ARMv7, iCortex-A8, iCortex-A9 (njengaleyo esetshenziswe ku-PandaBoard).
I-RISC OS Kuyisistimu elula kakhulu, ukufakwa okuphelele kuthatha ngaphansi kuka-4 Mb. Ingafakwa kwimemori ye-Flash (eduze kwe-boot) ukuqala okusheshayo.
Uhlelo lulula kakhulu: ukubambisana okuningi, ukuvikelwa kwememori okuncane.
Kancane mayelana ne-RISC OS
Uhlelo lokusebenza ngumsebenzisi oyedwa. Yize iningi losetshenziswa lwanamuhla lokuvikela imicu eminingi (PMT) nezinhlelo zokusebenza kwedeskithophu eziningi, i-RISC OS inamathela ngohlelo lwe-CMT.
I-kernel yohlelo lokusebenza igcinwa ku-ROM, ukuhlinzeka ngesikhathi esisheshayo sokuqalisa nokuvikeleka ekukhohlisweni kohlelo lokusebenza
Uhlelo inikeza izindlela eziningi lapho umqambi anganqabela futhi aguqule ukusebenza kwawo. Lokhu kwenza lula umsebenzi wokuguqula ukusebenza kwawo, kungaba ku-GUI noma ngokujulile.
Uhlelo lwefayela
Uhlelo lwefayela eIqondiswe ngevolumu: Izinga eliphezulu lokulandelana kwamafayela liyivolumu (idiski, isabelo senethiwekhi) enamathiselwe nohlobo lwesistimu yefayela.
Ukunquma uhlobo lwefayela, isistimu yokusebenza isebenzisa imethadatha esikhundleni sezandiso zefayela.
Ikholoni isetshenziselwa ukuhlukanisa uhlelo lwefayela kolunye uhlangothi lwendlela; impande imelwe ngu- $ () futhi izinkomba zihlukaniswe yisitobha esigcwele (.).
Izandiso zohlelo lwamafayela angaphandle ziboniswa nge-slash (example.txt iguqulwa ibe yisibonelo / txt).
Lokhu ivumela ukuphathwa okusobala kwamafayela namafayela afanayo, Zivela njengezinkomba ezinezici ezithile ezikhethekile. Amafayela angaphakathi kwefayela lesithombe avela esigabeni sabaphathi esingezansi kwefayela eliyinhloko.
Amafomethi wefayela
Uhlelo olusebenzayo isebenzisa imethadatha ukuhlukanisa amafomethi wefayela. Imodyuli yeMimeMap ibalaza ezinye izinhlobo zamafayela ezejwayelekile kusuka kwamanye amasistimu kuya kuzinhlobo zamafayela.

I-interface ye-WIMP isuselwa kumphathi wewindows oyisitaki futhi ifaka izinkinobho ezintathu zegundane (okuthiwa Khetha, Imenyu, kanye no-Lungisa), amamenyu azwela kokuqukethwe, ukulawulwa koku-oda kwewindi (okungukuthi, ukubuyela emuva), nokugxila kwewindi okunamandla (iwindi lingaba nokugxila kokufaka kunoma isiphi isikhundla esitaki).
Ibha yesithonjana (i-Dock) iqukethe izithonjana ezimele ama-disk drive afakiwe, amadiski e-RAM, izinhlelo zokusebenza ezisebenzayo, izinsiza zohlelo, kanye namachweba: amafayela angasebenzi, izinkomba, noma izinhlelo zokusebenza. Lezi zimpawu zinamamenyu wokuqukethwe futhi zisekela ukuhudula bese uphonsa.
Aplicaciones
Uhlelo lokusebenza lwe-RISC luhamba nezinhlelo eziningi zedeskithophu njenge-software efakwe kuqala.
Ekugcineni, uhlelo lokusebenza lwe-RISC luza nenguqulo ye-BBC BASIC, ekuvumela ukuthi uqale ukwenza izinhlelo ngolimi olulula lokufinyelela.
Ungayithola kanjani iRisc OS?
Cishe njalo ngonyaka kusukela ngo-1987, okungenani kuvele umshini owodwa ohambisanayo we-RISC OS. Okudume kakhulu namuhla yiRaspberry Pi 3, BeagleBoard, nePandora.
Abanye abakhiqizi banikela ngamakhompyutha azinikele, okuvumela ukuba ube nomshini osheshayo wokubonga, ngokwesibonelo, ekusetshenzisweni kwe-SATA ukuxhuma i-SSD (esheshayo kunekhadi le-SD).
Ekugcineni, eLolu hlelo olunjalo ngezindawo ezikhiqizayo noma imisebenzi yansuku zonke alusebenzi.
Kodwa-ke, ilusizo kakhulu kulabo abafundela izinhlelo futhi uhlelo lusebenza ngokuphelele njengesethenjwa sokuthambekela ekwakhiweni nasekusebenzeni kohlelo lokusebenza.
Ukuze uthole lolu hlelo ku-Raspberry Pi yakho, i-NOOBS yenza kube lula ukufaka nokuqalisa uhlelo lokusebenza lwe-RISC.
