Tiag tiag-lub sijhawm ua haujlwm operating system Nco faib

Mar 08, 2019


Nco lub sij hawm yog qhov tseemceeb rau kev khiav haujlwm hauv lub sijhawm ua haujlwm tshaj li lwm qhov kev khiav haujlwm.


Ua ntej, kev ruaj ntseg tsis tuaj yeem yog lub cim xeeb txaij (cim xeeb uas raug faib tab sis tsis tso tawm tom qab siv). Tus ntaus ntawv yuav tsum ua haujlwm tas mus li, tsis tas yuav tsum tau siv lub reboot. Vim li no, lub cim xeeb ntawm lub cim xeeb yog cim rau kev ntseeg. Thaum twg ua tau, txhua yam yuav tsum tau nco nco yog qhov tseem ceeb ntawm lub sij hawm sau tseg.


Lwm cov laj thawj yuav tsum tsis txhob muaj lub cim xeeb ntawm kev cim xeeb yog qhov cim fragmentation. Nres qee zaus thiab tso me me ntawm kev nco, qhov teeb meem tshwm sim tau tshwm sim thaum muaj qhov cim xeeb muaj peev xwm muab faib rau ob peb seem thiab RTOS tsis muaj peev xwm faib cov txheej txheem loj nrawm ntawm lub cim xeeb, tab sis nws muaj kev nco txaus. Qhov thib ob, qhov ceev ntawm kev faib yog ib qho tseem ceeb. Tus txheej txheem cim tseg lub tswv yim soj ntsuam ib daim ntawv teev txuas ntawm indeterminate ntev mus nrhiav kev ywj pheej tsis haum, uas yog tsis tsim nyog nyob rau hauv ib qho RTOS txij thaum lub sij hawm nco tau tshwm sim nyob rau hauv ib qhov nqi ntawm lub sijhawm.


Vim hais tias cov neeg tsav tsheb muaj ntau dua thiab ntau lub sij hawm uas tsis tuaj yeem ua ntej, pauv mus rau disk cov ntaub ntawv tsis raug siv rau tib lub ntsiab lus raws li RAM qhov kev sib tham tau tham saum toj no.


Qhov yooj yim tsuam-loj-blocks algorithm ua haujlwm zoo heev rau cov txheej txheem yooj yim rau kev vim nws tsis tshua muaj nyiaj siv ua haujlwm.
