Raws li lub zej zog qhib tau tsim, cov embedded systems kuj tau nrov zuj zus. Kev xaiv ib lub embedded operating system uas tsim nyog tuaj yeem ua rau muaj ntau yam haujlwm kom siv tau hauv ib lub cuab yeej. Cov Linux distros, Yocto thiab Debian, yog qhov kev xaiv zoo tshaj plaws rau embedded systems. Cia peb saib qhov zoo sib xws thiab qhov sib txawv ntawm Yocto thiab Debian kom xaiv qhov yog rau koj txoj kev lag luam.
Yocto tsis yog ib lub distro linux uas raug cai tiag tiag, tab sis yog ib lub framework rau cov neeg tsim khoom los tsim ib lub distro Linux raws li lawv tus kheej xav tau. Yocto muaj ib lub framework hu ua OpenEmbedded (OE), uas ua kom yooj yim rau txoj kev tsim lub embedded system los ntawm kev muab cov cuab yeej tsim kho tsis siv neeg thiab cov software package nplua nuj. Tsuas yog los ntawm kev ua tiav cov lus txib, tag nrho cov txheej txheem tsim kho tuaj yeem ua tiav tau, suav nrog kev rub tawm, decompressing, patching, configuring, compiling thiab generating. Tsis tas li ntawd, nws tso cai rau cov neeg siv los nruab tsuas yog cov tsev qiv ntawv tshwj xeeb thiab dependencies xav tau, uas ua rau Yocto-system siv qhov chaw nco tsawg dua thiab tuaj yeem ua tau raws li qhov xav tau ntawm embedded ib puag ncig nrog cov peev txheej tsawg. Hauv ntej, cov yam ntxwv no ua lub luag haujlwm rau Yocto siv rau cov embedded systems uas raug kho kom haum.
Debian, ntawm qhov tod tes, yog ib qho kev faib ua haujlwm thoob ntiaj teb uas paub tab. Nws siv native dpkg thiab APT (Advanced Packaging Tool) los tswj cov pob khoom software. Cov cuab yeej no zoo li cov khw muag khoom loj, qhov twg cov neeg siv tuaj yeem nrhiav tau txhua yam software uas lawv xav tau, thiab lawv tuaj yeem tau txais nws yooj yim. Yog li ntawd, cov khw muag khoom loj no yuav siv ntau qhov chaw cia khoom. Hais txog qhov chaw ib puag ncig desktop, Yocto thiab Debian kuj qhia qhov sib txawv. Debian muab ntau yam kev xaiv ib puag ncig desktop, xws li GNOME, KDE, thiab lwm yam, thaum Yocto tsis muaj ib puag ncig desktop tiav lossis tsuas yog muab ib puag ncig desktop sib dua. Yog li Debian yog qhov tsim nyog dua rau kev tsim kho ua lub desktop system dua li Yocto. Txawm hais tias Debian lub hom phiaj yog muab ib puag ncig operating system ruaj khov, ruaj ntseg thiab yooj yim siv, nws kuj muaj ntau yam kev xaiv kho kom haum rau cov kev xav tau tshwj xeeb.
| Yocto | Debian | |
| Qhov Loj ntawm OS | Feem ntau tsawg dua 2GB | Ntau tshaj 8GB |
| Desktop | Tsis tiav los yog tsis hnyav | Ua tiav |
| Cov ntawv thov | Embedded OS uas hloov kho tau tag nrho | OS zoo li server, desktop, cloud computing |
Hauv ib lo lus, hauv thaj chaw ntawm lub operating system qhib, Yocto thiab Debian muaj lawv tus kheej qhov zoo. Yocto, nrog nws qib siab ntawm kev hloov kho thiab kev ywj pheej, ua tau zoo hauv embedded systems thiab IOT devices. Debian, ntawm qhov tod tes, yog qhov zoo tshaj plaws hauv server thiab desktop systems vim nws qhov ruaj khov thiab cov software library loj.
Thaum xaiv ib lub operating system, nws yog ib qho tseem ceeb heev uas yuav tsum soj ntsuam nws raws li qhov xwm txheej thiab cov kev xav tau ntawm daim ntawv thov tiag tiag. 3Rtable muaj ob lub ntsiav tshuaj rugged raws li Yocto:AT-10ALthiabVT-7AL, thiab ib qho raws li Debian:VT-10 IMXOb leeg muaj lub plhaub tsim khoom ruaj khov thiab kev ua haujlwm siab, uas tuaj yeem ua haujlwm ruaj khov hauv qhov chaw ib puag ncig hnyav, ua tau raws li qhov yuav tsum tau ua ntawm kev ua liaj ua teb, kev khawb av, kev tswj hwm nkoj, thiab lwm yam. Koj tsuas tuaj yeem qhia rau peb koj cov kev xav tau tshwj xeeb thiab cov xwm txheej thov, thiab peb pab neeg R & D yuav soj ntsuam lawv, ua qhov kev daws teeb meem zoo tshaj plaws thiab muab kev txhawb nqa kev tshaj lij rau koj.
3Rtablet yog lub tuam txhab tsim cov ntsiav tshuaj ruaj khov thoob ntiaj teb, cov khoom lag luam uas muaj npe nrov rau kev ntseeg tau, ruaj khov thiab muaj zog.
