Tauira o ngā pūnaha whakahaere wā-tūturu. Tauira o ngā pūnaha whakahaere whatunga

Ko te pūnaha whakahaere i te wā tūturu (RTOs) - tenei OS, e whakapūmau i te tetahi kaha mo te wā wā tomu'a. Hei tauira, kia hangaia ai reira kia rite ki te whakaatu i riro he ahanoa kua wātea mō te karetao i runga i te raina whakaminenga. Whakaröpütia taua coatings rite "pakeke", me te "ngohengohe."

amo pūnaha whakahaere Hard wā-tūturu e kore e taea te mahi i te tātaitanga, ki te kahore he wātea i te wā whakaritea (e mutu tenei mahi i roto i te kore) i te ahanoa.

Ka haere tonu te pūnaha whakahaere ngohengohe i roto i te rārangi whakaminenga wā-tūturu i raro i enei tikanga ki te whakahaere, engari kia waiho te putanga raro no te mea e kore e taea e ki te kia hanga e wātea ana i roto i te wa e tika ana, me te hua te whakaurunga e te karetao e poto huakore.

I mua i te whakaatu i ngā tauira o ngā pūnaha whakahaere wā-tūturu, e hiahia ana koe ki te matau i te peculiarities o ratou te whakamahi. Ētahi o ēnei OS e hanga mō ngā tono motuhake, i ētahi atu - mo te atu whānui. Ano, Kei te ētahi wā whakamahia hoki etahi casing-whakaaro whānui mō te mahi i roto i te wā tūturu. Ka rite ki taea tauira o tenei momo o ngā pūnaha whakahaere te mahi pai-mohiotia Windows 2000 ranei IBM Microsoft / 390. E ko, ara, ki te kore e whakatau i te pūnaha mahi etahi whakaritenga, kia whai i te reira mau huru e tukua ki a tatou whakaaro i te reira rite te otinga mo te raruraru tono motuhake i roto i te wā tūturu.

Tauira o ngā pūnaha whakahaere , me to ratou kiripuaki

I roto i te whānui, i te pūnaha whakahaere e te āhuatanga e whai ake nei o te wā tūturu:

• Multitasking.
• rerenga tukanga e taea te ngā.
• He maha rawaka o ngā taumata haukoti.

Kei te maha ngā pūnaha whakahaere-wā Real whakamahia i roto i hiako iti tāmau, e kua whakamahia i roto i te hōputu microdevices. Hei tauira, e taea te whakaaro etahi o te karihi rite te pūnaha kotahi-tasking whakahaere (tauira: te pata hei wāhanga o iOS, Android, etc ...) I roto i te wā tūturu. Heoi, ki te mahi i a ratou mahi rapu atu wāhanga o te pūrere, hei tauira, taraiwa. Ko te aha tonu-parirau pūnaha whakahaere he wa-tūturu, rite ki te tikanga, he neke atu i te tika te pata.

He tauira angamaheni ko te tono RTOs HDTV-kaiwhiwhi me te whakaaturanga. kia lau ia te tohu mamati, Pūwhiwhi reira me te whakaatu i roto i te puka o raraunga taumai. ka kia kitea rite te ataata pika, me / oro ranei e mio'i tetahi e whakaroa.

Heoi, ka pai te oro "hoatu tauira o ngā pūnaha whakahaere o tenei momo," e pā ana ki te whakahua i te ingoa tino rongonui. He aha wāhanga o tenei rōpū?

VxWorks i kamupene WindRiver

VxWorks Ko te pūnaha whakahaere wā-tūturu whakawhanakehia rite te pūmanawa kamupene ki te awhina o WindRiver. A, no te tuatahi tukua i roto i te tau 1987, VxWorks i hangaia tuatahi mō te whakamahi i roto i ngā pūnaha tāmau e rapua e te wā-tūturu me mahi deterministic. Ko te kupu, tauira o tenei momo o ngā pūnaha whakahaere e whakamahia i roto i te wāhi tiaki me te haumaru, ahumahi rerekē (ngā te Aerospace me korero), te hanga o ngā pūrere hauora, taputapu ahumahi, karetao, pūngao, te whakahaere waka, hanganga whatunga, te whakapai ake i te hikohiko automotive me kiritaki.

tautoko VxWorks te Intel (x86, tae atu i te putanga hou o IntelQuarkSoC me x86-64), MIPS, PowerPC, SH-4, a ARM-hoahoanga. mai te reira ki te pata kaha RTOs, Middleware, tautoko hoki pōkai tāpiri-i runga i hāngai ana utu-a hangarau pūmārō i etahi atu kaihanga. I roto i tona take hou - nga VxWorks 7 - te pūnaha kua ake ki te modularity me te whakahōu kia roto te pata OS te motuhake i te Middleware, tono, me ētahi atu pōkai.

QNX Neutrino

Hoki tauira matarohia o tenei momo o ngā pūnaha whakahaere - etahi Unix-rite anga. He pera ano te QNX Neutrino, tuatahi whakawhanakehia i roto i te tīmatanga o nga 1980, i te kamupene Canadian Quantum Software Systems. I te pae hopea, riro te whanaketanga o parakipere i roto i 2010. QNX Ko tetahi o te pūnaha microkernel whakahaere arumoni angitu tuatahi, whakamahia nei i roto i ngā whakaaro, tae atu motokā me waea pūkoro.

FreeRTOS

FreeRTOS Ko te OS karihi wā tūturu-rongonui tāmau whakaaro, utaina nei te 35 microcontrollers. toro te reira i raro i raihana GPL ki te rāhuitanga atu me okotahi kōwhiringa. Tikanga opani te ünga, i te whakawāteatanga e āhei ngā kaiwhakamahi ki te whakamahi i ō rātou ake waehere ki te pūtake kati, i te tiaki i te matua ano. Te reira i te kupu whakahaere te FreeRTOS whakamahi i roto i to koutou ake tono.

CE Windows

Windows Embedded Kiato - ko te pūnaha whakahaere o te subfamily whakawhanakehia "Microsoft" kaporeihana i roto i te hapu Tāmau Windows o ngā hua. Rerekē Paerewa Embedded Windows, e hāngai ana nei i runga i Windows NT, enei tauira o ngā pūnaha whakahaere whakamahi pata kākano motuhake. whakarato "Microsoft" kamupene raihana CE Windows mō kaiwhakanao taputapu taketake nei e taea te whakarerekē me te hanga i to ratou ake atanga kaiwhakamahi, whakarato i te pūtake hangarau mō tenei.
