Qee zaum hu ua kev sib dhos lub ASM, ib lus sib dhos yog qib qis programming lus . Cov kev pab cuam sau rau hauv cov lus sib dhos yog sau los ntawm ib sib dhos . Txhua sib dhos muaj nws tus kheej lus sib dhos , uas yog tsim los rau ib tug tshwj xeeb computer architecture.
Tsis tas li ntawd, qhov piv txwv lus sib dhos yog dab tsi?
Ib lus sib dhos yog ib qho programming qis lus tsim los rau ib hom processor tshwj xeeb. Tej zaum nws yuav ua tau los ntawm kev sib sau ua ke code los ntawm high-levelprogramming lus (xws li C / C ++) tab sis kuj tuaj yeem sau los ntawm kos. Hauv qab no yog qee qhov piv txwv ntawm cov lus qhia txhawb nqa los ntawm x86 processors.
Qhov thib ob, cov lus sib dhos ua haujlwm li cas? Koj CPU tsis ua haujlwm kev sib dhos . Cov sib dhos converts nws mus rau hauv lub tshuab code . Qhov txheej txheem no nyob ntawm ob qho tib si lus sib dhos thiab thetarget computer architecture. Cov lus qhia hauv assemblycode daim ntawv qhia rau cov kev qhia tiag tiag thiab sau npe rau CPU architecture koj tab tom npaj.
Ua raws li qhov xav tau, cov lus sib dhos siv rau dab tsi?
Hnub no, lus sib dhos yog siv Feem ntau rau kev kho vajtse ncaj qha, nkag mus rau cov lus qhia tshwj xeeb processor, lossis daws teeb meem kev ua haujlwm tseem ceeb. Typicaluses yog cov cuab yeej tsav tsheb, cov tshuab qis qis, thiab lub sijhawm tiag tiag.
Dab tsi yog mnemonic hauv lus sib dhos?
Hauv computer sib dhos (los yog kev sib dhos ) lus , a mnemonic yog ib qho luv luv rau kev ua haujlwm. Feem ntau, a mnemonic yog lub cim lub npe rau asingle executable tshuab lus kev qhia (ib qho opcode), thiab muaj tsawg kawg yog ib qho opcode mnemonic txhais rau txhua lub tshuab lus kev qhia.

Cov ntaub ntawv sib dhos yog dab tsi?
Kev sib dhos yog ib cov ntaub ntawv uas tau txais los ntawm lub compiler raws li kev ua tiav ntawm txhua qhov. NET application. Nws tuaj yeem yog Dynamic Link Library lossis cov ntaub ntawv ua tiav. Nws tsuas yog tsim ib zaug rau ib daim ntawv thov thiab thaum txhua qhov kev sib sau ua ke tom qab lub rooj sib txoos tau hloov kho
Dab tsi yog qhov sib txawv ntawm cov ntaub ntawv sib sau ua ke thiab cov ntaub ntawv tsis sib xws?
Kev sib sau cov ntaub ntawv yog sau thiab sau cov ntaub ntawv; kom disaggregate cov ntaub ntawv yog rhuav tshem cov ntaub ntawv sib sau ua ke rau hauv cov khoom siv lossis cov ntaub ntawv me me
Dab tsi cuam tshuam cov lus qhia hauv kev sib txuas lus tsis yog lus?
Cov lus qhia cuam tshuam yog qhov hais lus thiab tsis hais lus ntawm kev cuam tshuam (kev xav). Cov kev qhia no tuaj yeem yog los ntawm lub ntsej muag, kev piav tes piav taw thiab lub cev lus, ntim thiab lub suab ntawm lub suab, luag, quaj, thiab lwm yam. Kev cuam tshuam cov duab tuaj yeem hloov kho lossis cuav yog li ib qho tuaj yeem tshwm sim, thaum lawv hnov lwm (piv txwv li luag ntxhi thaum tu siab)
Dab tsi yog accumulator register hauv lus sib dhos?
Lub accumulator yog ib lub npe rau lub sij hawm luv luv, nruab nrab cia ntawm cov lej lej thiab cov ntaub ntawv logic hauv lub computer CPU (central processing unit). Thaum cov lej tau txiav txim siab, nws raug sau rau hauv lub cim xeeb tseem ceeb lossis rau lwm tus sau npe
Dab tsi yog qhov sib txawv tseem ceeb ntawm kev sib txuas lus tsis sib xws thiab kev sib txuas lus taw qhia?
1. Hauv kev sib txuas lus tsis muaj kev sib txuas lus tsis tas yuav tsim kev sib txuas ntawm qhov chaw (sender) thiab qhov chaw (receiver). Tab sis nyob rau hauv kev sib txuas-taw qhia kev sib txuas lus kev sib txuas lus yuav tsum tau tsim ua ntej hloov cov ntaub ntawv
