Cov kev khiav hauj lwm hauv nruab nrog tsis muaj dab tsi tshiab rau lub ntiaj teb ntawm hluav taws xob. Lawv tau raug ntsia rau ntawm ntau yam ntawm cov neeg siv khoom siv hluav taws xob kom tso cai rau lawv ua haujlwm hauv ntau yam haujlwm sib txawv. Embedded operating systems tsis txawm tshiab rau kev ua haujlwm ntawm computers.
Qee lub sij hawm cov embedded operating systems yog hu ua systems ntawm ib tug nti.
Handheld khoos phis tawj xws li Xibtes thiab Windows Mobile txhua tus siv cov qauv ntawm embedded operating systems uas tau khaws cia rau hauv lub cim xeeb sab hauv es tsis yog khau raj ntawm lub disk.
Dab tsi yog Embedded OS?
Ib qho kev ua haujlwm embedded yog qhov tseem ceeb ntawm kev ua haujlwm tsis raug tshem tawm nrog qee qhov tshwj xeeb. Nws feem ntau yog tsim los rau cov haujlwm tshwj xeeb rau kev tswj cov khoom siv hluav taws xob. Piv txwv li, txhua lub xov tooj ntawm tes siv lub operating system uas khau raj thaum lub xov tooj qhib. Nws tuav tag nrho cov yooj yim interface thiab nta ntawm lub xov tooj. Cov kev pab cuam ntxiv tuaj yeem thauj mus rau hauv xov tooj, tab sis lawv feem ntau yog Java daim ntawv thov uas khiav saum lub operating system.
Cov kev khiav hauj lwm hauv nruab nrog tuaj yeem yog cov kev cai sau ua haujlwm tshwj xeeb rau lub cuab yeej lossis ib qho ntawm ntau lub hom phiaj kev ua haujlwm uas tau hloov kho kom ua haujlwm saum toj ntawm lub cuab yeej. Cov kab ke ua haujlwm feem ntau suav nrog Symbian (cov xov tooj ntawm tes), Windows Mobile / CE (handheld PDAs) thiab Linux. Nyob rau hauv cov ntaub ntawv ntawm ib tug embedded OS ntawm tus kheej lub computer, qhov no yog ib tug ntxiv flash nco nti ntsia rau ib tug motherboard uas yog siv tau rau khau raj los ntawm lub PC.
Hloov kho Embedded Operating Systems
Cov kev khiav hauj lwm hauv nruab nrog tuaj yeem hloov kho dua yog tias cov nti lawv khaws cia yog flashable. Piv txwv li, koj lub tsev Wi-Fi router muaj ib qho kev ua haujlwm embedded; Thaum koj rub tawm cov firmware tshiab, koj nyem lub nti hauv lub router nrog kev hloov kho tshiab ntawm lub operating system.
Qee qhov kev kos OSes tsis tuaj yeem hloov kho los ntawm kev tsim. Piv txwv li, nyob rau hauv ib co automated teller machines, ib co Cheebtsam yuav tsis tau upgraded raws li kev ruaj ntseg ceev faj tiv thaiv tampering.
