JK-flip-flop. Umgomo we operation, funtsktsionalnye wesifunda isithebe samaqhuzu ayizinamba

A inhlamvu umshini elula digital. It has ukuzinza ezimbili isimo. Omunye wabo kusethelwe ku- "1", nomunye - "0".

Esikhathini indlela ukugcwaliseka uxhumano okunengqondo ukuhlukanisa lezi zinhlobo ezilandelayo amadivaysi okukhulunywa: JK-flip-flop, RS-flip-flop, T-flip-flop, D-flip-flop , njll ...

Ekhulunywe yethu namuhla uhlobo imishini JK. Ziyahlukahluka kuye kusukela RS-amadivayisi lapho isetshenziswa ulwazi okokufaka enqabela RS-trigger, egcinwe nabokhulumile ulwazi lwabo.

Wethule ukunakwa yakho etafuleni gxuma, echaza umsebenzi JK-flip-flop. Ngo ukunciphisa Carnot Kata etholakala isici kwesibalo yedivayisi okukhulunywa ngawo: Q (t + 1) = K't Qt V Jt Q't.

Ithebula ibonisa ukuthi isimo zedivayisi uzimisele kuphela izimiso ulwazi okokufaka J kanye K, kodwa futhi isimo okukhipha Qt, elalikade ezanquma JK-flip-flop. Lokhu kukuvumela ukwakha uhlelo functional amadivayisi kangaka ezimbili isigaba imishini RS hlobo. JK-amadivayisi zokuvumelanisa iphinde indlela.

Ukuze umklamo we JK-flip-flop RS yohlobo ezimbili isigaba amadivayisi zokuvumelanisa iyadingeka ukuxhuma ezimbili esiteji RS feedbacks umshini okukhiphayo kuya okokufaka of KANYE amasango isigaba saso sokuqala.

I yokusebenza Umgomo we JK-trigger: Uma ulwazi (J kanye K) kudivayisi isetshenziswa ezingeni uvo zero ke ekhishwa KANYE-HHAYI (1 no-2) isethelwe iqophelo elilodwa, kanye JK-flip-flop uzobuyisa isimo salo. Ngokwesibonelo, Q kuyoba ulingana logic zero, Q '- iyunithi okunengqondo. Kulokhu, lapho J isignali no-C, ilingana iyunithi okunengqondo KANYE-HE1 okokufaka setha futhi bacabanga zero, ngokulandelana, ezingeni logic esisodwa itheku wokuqala T-flip-flop. Lapho kukhishwa i-signal iwashi (C zero) isimo idivayisi ye-T-uhlobo logic-zero ezingeni okukhiphayo kusukela FUTHI = HE3 ingadlulela uvo yesibili T-flip-flop. Ngenxa JK-flip-flop wokushintsha isimo logic nanye (lapho Q lingana kuze fike, futhi Q 'ilingana zero). Manje, uma okufakwayo flip-flop (K no C) isiginali okulingana logic eyodwa, ekhishwa KANYE-HE2 zero okunengqondo usungula T-flip-flop kuqala iqanda isimo. Ngemva kokukhipha isignali iwashi kusukela ekhishwa KANYE-HE4 logic zero ezizophasiswa uvo the automaton yohlobo T yesibili, futhi JK-flip-flop esitshalweni bacabanga zero isimo.

Ekuklanyweni eziyinkimbinkimbi logic izifunda ayadingeka izinhlobo ezahlukene amadivaysi. Ngakho-ke kusiza ukwenza jikelele uhlobo apharathasi angasetshenziswa ezimweni ezahlukene kanye ukuhlela kabusha. Ngo okuhlangene design wesifunda kabanzi kunazo D- zokuvumelanisa iphinde JK-flip-flops. Ngo amakhompyutha electronic kabanzi zisebenzisa digital JK-uhlobo imishini neqembu J, K futhi ezengeziwe ukufakwa R, S-okokufaka. iqembu ngamunye ngokuhlangana united elikuvumela ukuba sandise amathuba ngekulandzelana JK-flip-flop.

amadivaysi Automatic uhlobo esetshenziswa ekwakhiweni zokubala (ikhompyutha node ukuthi wenza ikhodi akhawunti nokugcina inani abalwa signal). Ngokwesibonelo, lesi sithombe sibali JK-flip-flops. Inhlangano isakhi counter kanambambili nge ukudluliselwa parallel kuba lula kakhulu uma ukwakha kumadivayisi JK-hlobo nge esishunyekiwe izakhi logic I.

Futhi, lezi trigger ziye zasetshenziswa ekwakhiweni shift amarejista.

Shift amarejista - kukhona ISIZINDA kokwenza offset Imininingwane kanambambili kwesokunene nezinhlanu kwesobunxele kubukwa irejista yalabakhona ngokuvumelana amasignali control.
