Zitsanzo za kachitidwe opaleshoni zenizeni nthawi. Zitsanzo za kachitidwe opaleshoni maukonde

The opaleshoni dongosolo pompopompo (RTOS) - uyu Os, limene linapatsa mphamvu ena anakonzeratu nthawi imeneyi. Mwachitsanzo, akhoza lakonzedwa kuti kusonyeza kuti chinthu wakhala alipo kwa Makina pa mzere msonkhano. zokutira oterowo wachinsinsi monga "mwakhama, '' zofewa."

zenizeni nthawi Mwakhama machitidwe opaleshoni amaganiza kuti mawerengedwe sangathe aphedwe, ngati chinthu palibe pa nthawi anasankha (opaleshoni adzatha kulephera).

The opaleshoni dongosolo zofewa mu zenizeni nthawi msonkhano mzere pansi pa zikhalidwe izi adzapitiriza ntchito, koma linanena bungwe kungakhale m'munsi chifukwa maofesi sangathe kupezeka mu nthawi yake, ndi chifukwa kuti loboti adzatero mongoyembekezera wosabereka.

Pamaso kupereka zitsanzo za kachitidwe opaleshoni zenizeni nthawi, muyenera kumvetsa peculiarities wa ntchito zawo. Ena mwa Os izi analengedwa ndi ntchito yake, pamene ena - chifukwa kwambiri ambiri. Komanso, ena casing ambiri-cholinga zina amagwiritsidwanso ntchito ntchito mu nthawi yeniyeni. Monga zitsanzo za mtundu wa kachitidwe opaleshoni angachichite odziwika Windows 2000 kapena IBM Microsoft / 390. Ndiko kuti, ngakhale opaleshoni dongosolo si zofunika kuzikwaniritsa, n'kutheka makhalidwe amatithandiza kuona ngati njira kwa mavuto enieni ntchito mu nthawi yeniyeni.

Zitsanzo za kachitidwe opaleshoni ndi mapangidwe awo

Ambiri, za opaleshoni dongosolo la pompopompo ali ndi makhalidwe awa:

• Multitasking.
• utuluke ndondomeko zomwe zingagwiritsidwe prioritized.
• A okwanira milingo usokoneze.

kachitidwe opaleshoni zenizeni nthawi Mankhwalawa amagwiritsidwa ntchito mu zikopa yaing'ono ophatikizidwa, amene ntchito mu microdevices mtundu. Mwachitsanzo, ena mwa phata akhoza ankaona ngati umodzi-tasking opaleshoni dongosolo (Zitsanzo: ngale monga mbali ya iOS, Android, etc ...) Mu pompopompo. Komabe, kugwira ntchito zawo amafuna zigawo zina za chipangizo Mwachitsanzo, madalaivala. Ndicho chifukwa zonse kunachitika opaleshoni dongosolo ndi zenizeni nthawi, monga ulamuliro, ndi koposa monga ngale ya.

Chitsanzo chabwino ndi ntchito RTOS HDTV-wolandila ndi mtima. Iye ayenera kuwerenga chizindikiro digito, decode ndi chionetsero mu mawonekedwe a deta ukubwera. Kuchedwa aliyense adzakhala noticeable monga kanema mapikiselo ndi / kapena phokoso ndi oipa.

Komabe, pamene phokoso kusangalatsa "apereke zitsanzo za kachitidwe opaleshoni ya mtundu umenewu," amatanthauza mayina wotchuka. Kodi m'gulu?

VxWorks ku makampani WindRiver

VxWorks ndi zenizeni nthawi opaleshoni dongosolo kuyambira mapulogalamu kampani mothandizidwa ndi WindRiver. Pamene woyamba anamasulidwa mu 1987, VxWorks unali cholinga ntchito mu kachitidwe ophatikizidwa amene amafuna zenizeni nthawi ndi ntchito deterministic. Motero, zitsanzo za mtundu wa kachitidwe opaleshoni ntchito m'madera chitetezo, mafakitale osiyana (makamaka Azamlengalenga ndi chitetezo), kupanga zipangizo zachipatala, mafakitale zipangizo, Makina, mphamvu kasamalidwe zoyendera zomangamanga network patsogolo magalimoto ndi ogula zamagetsi.

VxWorks kuthandiza Intel (x86, kuphatikizapo Baibulo latsopano IntelQuarkSoC ndi x86-64), MIPS, PowerPC, SH-4, ndi mkono zomangamanga. Iwo ubwera zamphamvu RTOS ngale, middleware, thandizo amalipiritsa ofotokoza pokha-pa phukusi ndi umisiri hardware ku opanga ena. Mu magazini atsopano - ndi VxWorks 7 - dongosolo wakhala akweza kwa modularity ndi Mokweza kuti Os ngale uli mosiyana middleware ndi, ofunsira, ndi maphukusi ena.

QNX Neutrino

Komanso zitsanzo tingachipeze powerenga za mtundu wa kachitidwe opaleshoni - ena chipolopolo Unix ngati. Imeneyo ndiyo QNX Neutrino, poyamba anayamba mu 1980s oyambirira, Canada kampani kwadzidzidzi mapulogalamu Systems. Potsilizira pake, kupanga BlackBerry utapezeka mu 2010. QNX ndi imodzi mwa machitidwe woyamba malonda bwino microkernel opaleshoni, amene ntchito zipangizo zosiyanasiyana, kuphatikizapo galimoto ndi mafoni.

FreeRTOS

FreeRTOS ndi otchuka nyukiliya Os zenizeni nthawi ophatikizidwa zipangizo, amene yodzaza 35 microcontrollers. Munthu wotere pansi GPL chilolezo ndi chiletso zina ndi kuchotserapo okhulupirika. Chiletso limaletsa benchmarking, pamene wosamasula walola ogwiritsa ntchito malamulo awo omwe ndi gwero chatsekedwa, pokhalabe pachimake yokha. Choncho facilitates FreeRTOS ntchito mafomu anu.

Windows CE

Windows ophatikizidwa Yaying'ono - ndi opaleshoni dongosolo la subfamily anayamba "Microsoft" bungweli mkati Mawindo ophatikizidwa banja katundu. Mosiyana Windows ophatikizidwa Standard, ozikidwa pa Windows NT, zitsanzo za kachitidwe opaleshoni ntchito yekha hybrid ngale. "Microsoft" kampani imapereka Windows CE azichitira opanga zida choyambirira amene akhoza kusintha ndi kulenga polumikizira awo wosuta, kupereka maziko luso ichi.
