Qhov kev txhais tau yog qhov khoom siv digital uas muaj peev xwm khaws cov ntaub ntawv me me. Hauv tshwj xeeb, thiaj li hu ua RS-triggers yog qhov tshwm sim heev. Lawv siv nyob rau hauv RAM me me zoo li qub, thaum lub qhov ntev ntawm ib lub xov tooj tsis tseem ceeb, piv txwv li, hauv CMOS lub cim xeeb ntawm kev teeb tsa ntawm lub computer motherboard.
Cov Lus Qhia
Kauj ruam 1
Siv lub microcircuit uas muaj tsawg kawg yog 2II-TSIS lub laj kab qhov rooj. Qhov no tuaj yeem yog tshwj xeeb, K155LA3 lossis K561LA7. Ob ntawm lawv muaj plaub lub ntsiab lus, thiab yog li ob txog RS-triggers tuaj yeem sib sau ua ke ntawm ib qho ntawm lawv. Tab sis microcircuit thib ob zoo dua siv, vim nws siv ntau zog tsis tshua muaj hwj chim.
Kauj ruam 2
Txuas cov zis ntawm ib qho ntawm lub rooj vag mus rau ib qho ntawm kev nkag ntawm lwm qhov. Ua tib yam nrog kev hwm rau tsim tawm ntawm cov txheej txheem thib ob lub ntsiab lus. Yog tias koj tau ua txhua yam yog, cov khoom yuav txuas nrog txhua tus "crosswise", thiab txhua ntawm lawv yuav muaj ib qho nkag dawb. Tsis txhob hnov qab thov siv fais fab rau lub microcircuit (nws cov txwv thiab txoj kev sib txuas ntawm lub peev xwm nyob ntawm seb hom microcircuit).
Kauj ruam 3
Txij li thaum lub ntsiab muaj sib npaug sib luag, tsis pom zoo hu ib qho ntawm lawv "sab saud", lwm qhov - "qis dua". Tam sim no, thaum cov zis ntawm thawj ntawm lawv yog lub hauv paus hauv paus, thiab qhov tsim tawm ntawm tus thib ob yog xoom, peb tuaj yeem xav tias qhov txhais nws tus kheej tau teeb tsa rau lub xeev kev sib koom ua ke, thiab nrog sib xyaw ua ke - mus rau lub xeev ntawm xoom Cov.
Kauj ruam 4
Txhawm rau qhov txhais tawm mus rau hauv lub xeev ntawm lub cav qhov tseeb, pub xoom rau qhov kev tawm tswv yim pub dawb ntawm lub sab saud, thiab ib qho mus rau qis dua ib qho (nco ntsoov tias tsis yog AND cov ntsiab lus tau siv, tab sis NAND cov ntsiab lus). Txheeb tus txhais mus rau xoom, ua qhov sib txawv.
Kauj ruam 5
Tab sis cov cuab yeej tseem ceeb ntawm RS-trigger, rau qhov nws tau siv, nws yog lub peev xwm los tswj lub xeev muab tom qab tshem qhov kev tswj hwm tau ua. Siv cov koog rau ob qho kev nkag, thiab tus txhais yuav nyob hauv lub xeev uas nws tau ua ntej.
Kauj Ruam 6
Tsis txhob siv lub pov thawj xoom rau ob qho kev nkag ntawm RS-flip-flop - hauv qhov no, nws yuav tsis nco qab lub xeev dhau los, thiab cov twg yuav tshwm sim ntawm ob qho ntawm nws qhov tawm. Los ntawm qhov pom ntawm cov binary logic, lub xeev zoo li no tsis muaj qab hau.
Kauj Ruam 7
Ntxiv nrog rau cov khoom siv cim xeeb, RS flip-flop tseem tuaj yeem siv tau rau hauv kev tiv thaiv hluav taws xob hauv Circuitry. Hauv qhov no, siv lub laj thawj siab rau ob qho ntawm nws txoj kev nkag los ntawm rub tawm-resistors. Txuas lub pob hluav taws xob tog mus rau qhov tshwm sim, uas hloov txuas txuas rau hauv av ib qho lossis lwm qhov ntawm nws qhov kev nkag.
