Ndechipi-chaiyo nguva uchishandisa hurongwa?

Ndezvipi kushanda hurongwa nguva chaiyo? Nyatsoteerera uchida kudzidza RTOS. Chokutanga, zviri chaiyo siyana anodawo mugadziriro, izvo waisiyana Generic uchishandisa hurongwa hwayo kuita uye nokukurumidza mumamiriro ezvinhu akaoma zvikuru. Pane pfungwa dzakawanda dzinoratidza chaizvo:

- RTOS - hurongwa kuti anokwanisa kupa mabasa anodiwa imwe nguva;

--chaiyo nguva gadziriro, iyo inozivikanwa nokuva kugara takagadzirira, uye kubudiswa mashoko zvinoonekwa vanoshandisa;

- "Gadziriro kutsanya", kunouya yakatsviriridza kwete mhinduro nguva RTOS, uye nguva yakakwana kushanda application.

Kukwana, zvinokosha achiteerera hunhu-zvechokwadi nguva uchishandisa hurongwa. Chinonyanya chinokosha inosimbiswa uye irambe mukupindura zviitiko. Mabasa chero sandara (mukuru uye pasi kukoshesa) hazvifaniri kuvhiringidza mumwe uye bvikinyidza mumwe. Yakakwirira azvipire zvinodiwa kuti mhinduro nguva chiitiko chaicho munguva chaiyo.

Mhando uchishandisa hurongwa nguva chaiyo

Gurai maererano zvirongwa: vanachandagwinyira (zvakaoma), nyoro (nyoro) uye dyidzana. A kumboongorora neimwe mhando.

Hard RTOS vane yakajeka nguva mhinduro yokuti chiitiko nenguva chaiyo. Muenzaniso: mumwe Hardware zvinodzongonyedza, ari kuratidza kuzvidzora rinorayira kuti kupatsanurwa kuti imwe nguva, sezvo rinowanikwa muna 100% nyaya.

Soft-chaiyo nguva hurongwa kubvumira 80-90% dzokushungurudzwa kuti tsaukai chaiyo muganhu nomumwe hurongwa. Asi Chikurukuru, sokunonoka izvi hazvina kuita kuti irreparable nemigumisiro.

Dyidzana RTOS zvinosanganisira munhu chinhu (kana munhu wakamirira mhinduro kubva hurongwa pashure mirayiridzo kana mirayiro ravakapiwa).

Chinonyanya dzakakurumbira chaizvo nguva anodawo hurongwa hwavo unhu

RTOS Most - chine gedhi uye pamusoro pavo zvakaoma kuwana hwakadzama mashoko. The kambani kwakasimbiswa WindRiver Systems VxWorks (zvakaoma RTOS) nokuti midzi Software kukura pamusoro PC. Zvinonzi inobva hondo kombiyuta, iro yaiitisa kukura software, uye nemhosva kombiyuta, apo rinoshandiswa pasi VxWorks kuzvidzora.

Izvi-chaiyo nguva uchishandisa hurongwa - shirokonastraivaemye, asi Software modules hazvigoni kushandiswa nenzira dzakasiyana ezvinhu, unoita kuti zvikuru zvakawanda kushandiswa. Benefits dzinosanganisira:

- Unlimited nhamba mabasa.

- The Nhamba kukoshesa - kusvikira 256.

- mabasa dzakarongwa cyclically kana kukosha.

- semaphores, izvo kubatsira kutarisira yakaoma hurongwa kupfuma.

Realtime uchishandisa maitiro QNX Neutrino Realtime Operating System - the brainchild wekambani QNX Software Systems. Zvinonzi kwakavakirwa muchinjikwa Server mapurani uye kunoratidzwa hombe multi-tasking kuti panzvimbo yokutanga muoti. Nechimwe chine maatomu akafanana wegadziriro inoshanda vakazvimiririra: chero chikwata anogona vakazvimiririra kuti ritangezve pamwe zvikanganiso nokukundikana pasina kukanganisa kushanda musimboti kana zvimwe zvinoriumba. Rinewo yakadzika configuration sunga inokosha musimboti, iyo anobvisa basa imwe nharaunda.

ChorusOS muenzaniso ane midzi uchishandisa hurongwa, iro zvinowanzoshandiswa foni. It anotsigira siyana telecommunication protocols, Java-zvigadzirwa, izvo anobvumira kuunzwa zviitiko itsva uye mafomu.

Kusiyana Os uye zvakajairika chinangwa

RTOS vakasiyana rwevanhu-chinangwa mugadziriro, deterministic yezvakaita basa, riri nokuda wakaoma kudzora nguva yakawandisa kugadzira mabasa. Pfungwa yokuti 'determinacy "rinotsanangura predefined nguva chinguva, panguva iyo akaita purogiramu-zvechokwadi nguva.
