Mienzaniso-zvechokwadi nguva uchishandisa hurongwa. Mienzaniso samambure uchishandisa hurongwa

The uchishandisa hurongwa nguva chaiyo (RTOS) - Os ichi, iyo inosimbisa imwe kukwanisa akafanorongerwa nguva penguva. Somuenzaniso, anogona yakagadzirirwa kuti kuratidza kuti chimwe chinhu zvava kuwanika nokuti robhoti pamusoro peungano mutsetse. coatings vakadaro semhosva "zvakaoma" uye "munyoro."

-Chaiyo nguva Hard anodawo hurongwa vanofungidzira kuti dzemaitirwe haagoni kuurayiwa, kana chinhu haisi kuwanikwa panguva akasarudzwa nguva (oparesheni iyi ichaguma kukundikana).

The nyoro uchishandisa wemuTesitamende-chaiyo nguva gungano mutsetse pasi izvi ezvinhu ucharamba uchishanda, asi goho kungava yakaderera nokuti zvivako havagoni kupiwa munguva yakafanira, zvikaguma kuti robhoti vachatitaka kwechinguva isingabereki.

Usati wapa mienzaniso-chaiyo nguva anodawo mugadziriro, unofanira kunzwisisa peculiarities avo kushandiswa. Zvimwe Os aya kusikirwa dzakananga mafomu, apo vamwe - nokuti mamwemazwi. Uyezve, vamwe vakawanda-chinangwa casing chiri dzimwe nguva inoshandiswa kushanda nenguva chaiyo. Sezvo mienzaniso iri mhando anodawo gadziriro anogona kuita vanozivikanwa Windows 2000 kana IBM Microsoft / 390. Kureva, kunyange kana uchishandisa hurongwa asingadi kusangana zvimwe zvinodiwa, zvinogona kuva unhu hunoita kuti tifunge rive kuitwa chaizvo kushanda matambudziko munguva chaiyo.

Mienzaniso anodawo hurongwa hwavo characterization

Kazhinji, kuti uchishandisa hurongwa nguva chaiyo ine zvinotevera unhu:

• Multitasking.
• Process Rwako zvinogona prioritized.
• A nhamba yakakwana kudimburira siyana.

Real-nguva anodawo hurongwa inowanzoshandiswa diki midzi namatebwe, izvo zvinoshandiswa microdevices format. Somuenzaniso, vamwe mwoyo kunogona kunzi sezvo vasina tasking uchishandisa hurongwa (mienzaniso: asi tsanga sechikamu IOS, Android, etc ...) Nokufamba kwenguva chaiyo. Zvisinei, kuita mabasa avo inoda zvimwe zvinoumba mudziyo Somuenzaniso, vatyairi. Ndicho chikonzero dzakazara uchishandisa hurongwa ndiyo-chaiyo nguva, somunhu mutemo, ndizvo zvinopfuura chete tsanga.

Muenzaniso uri kushanda RTOS HDTV-mugamuchiri chiratidzwa. Anofanira kuverenga digitaalinen chiratidzo, nzwisisa uye kuratidza zviri muchimiro kuuya mashoko. kunonoka Chero achava kuoneka sezvakaita Pixel vhidhiyo uye / kana inzwi iri kukanganiswa.

Zvisinei, kana kurira kufadza "kupa mienzaniso anodawo mugadziriro ino mhando," rinoreva kuti mazita dzakakurumbira. Ndezvipi boka iri?

VxWorks kubva Makambani WindRiver

VxWorks iri-chaiyo nguva uchishandisa ezvinhu zvakangonyuka-software proprietary tichibatsirwa WindRiver. Apo pakutanga kubudiswa muna 1987, VxWorks pakutanga akagadzirirwa kushandiswa mune midzi hurongwa zvinoda-chaicho nguva uye deterministic unongotaura. Saka, mienzaniso iyi mhando anodawo hurongwa zvinoshandiswa nekuchengetedzwa nekuchengeteka nzvimbo dzakasiyana maindasitiri (kunyanya Aerospace uye kudzivirira), anogadzira zvinhu zvokurapa mano, maindasitiri midziyo, robotics, simba, nezvifambiso zvakanaka, nomumbure kwezvivako, vanatsiridze motokari uye mutengi Electronics.

VxWorks rinotsigira Intel (x86, kusanganisira itsva shanduro IntelQuarkSoC uye x86-64), MIPS, PowerPC, SH-4, uye ruoko-mapurani. Anouya ane simba RTOS tsanga, middleware, rutsigiro muripo anotsanangura wedzera-pamusoro Mabhokisi uye Hardware michina nezvimwe vagadziri. In ichangobva nyaya yacho - kuti VxWorks 7 - kuti hurongwa kwave upgraded kuti modularity uye ndiwedzere zvokuti Os tsanga zvirimowo yoga kubva middleware, mafomu, uye dzimwe package.

QNX Neutrino

Uyewo mienzaniso klassiske kwaiita anodawo gadziriro - vamwe Unix-kufanana nevamwe. Ndizvo QNX Neutrino, pakutanga yakatanga mukutanga 1980s, yeCanada kambani Quantum Software Systems. Pakupedzisira, kukura Blackberry akanga awana 2010. QNX ndomumwe wokutanga kutengeswa kubudirira microkernel anodawo mugadziriro, iro rinoshandiswa nenzira dzakasiyana-mano, kusanganisira motokari uye maserura.

FreeRTOS

FreeRTOS munhu akakurumbira renyukireya Os chaiyo-nguva midzi mano, iyo akatakura 35 microcontrollers. Runosvika pasi GPL rezinesi chete mamwe yairambidzwa uye hako anosiyiwa. Kumanikana unorambidza benchmarking, ukuwo vakabvumirwa achibvumira vanoshandisa kushandisa bumbiro avo ane namahwindo tsime, apo kuramba pokupedzisira pachayo. Saka hwezvekukurukurirana kushandiswa FreeRTOS rwenyu mafomu.

Windows CE

Windows midzi Compact - ndiye anoita gadziriro yacho subfamily dzakabudirira "Microsoft" dzesangano mukati Windows midzi mhuri zvigadzirwa. Kusiyana Windows midzi Standard, iyo yakavakirwa Windows NT, mienzaniso iyi uchishandisa hurongwa vanoshandisa oga chemasanganiswa tsanga. "Microsoft" kambani rinopa Windows CE rezinesi kuti yepakutanga michina vagadziri vanogona kuchinja nokusika yavo User interfaces, kupa hwokugadzira hwaro ichi.
