T ku dhajisan-flop. Mabda'a hawlgalka, Bannaanka functional

Kiciyaan - qalab sahlan waa mashiin digital. Waxay leedahay laba dawladood ah xasiloonida. Mid ka mid ah shuruudahaas waxaa loo xilsaaray qiimaha a "1" iyo kuwa kale ee "0". xaaladda Device, iyo qiimaha macluumaadka binary oo waxa lagu kaydiyaa dhexdeeda, signalada saarka la go'aamiyo: Direct iyo rogay. In kiiska halkaas oo ka iman kara wax soo saarka si toos ah u dhisan, taas oo u dhiganta macquulka ah mid ka mid ah, markaas gobolka ka mid ah flip-flop loo yaqaan unugga (iman kara ee wax soo saarka rogay dhiganta macquul ah eber). Haddii wax soo saarka si toos ah ma aha iman kara, markaas xaalad keebka waxaa lagu magacaabaa eber.

Kiciyaasha waxa lagu tilmaamay by sifooyinka soo socda:

1. By habka ay u qoro macluumaadka (synchronous iyo asynchronous).

2. By habka macluumaadka gacanta (statistics, firfircoon, hal-yada, multistage).

3. By habka xaqiijinta isku xirka macquul ah (JK-flip-flop, QPR-kiciya T ku dhajisan-flop, D-flip-flop iyo noocyada kale).

Beegyada uu ugu weyn ee dhammaan noocyada kiciya yihiin: muddada ugu badan ee signal la gelin ah, markii dib u dhac looga baahan yahay bedesheen waddada tooska-flop, iyo u hogaansanka waqtiga hawlgalka.

In this article, aan ka hadalno noocan ah qalab, sida - T flip-flop. kiciya noocan oo kale ah waxay leeyihiin hal macluumaad (T) aqbasho oo keliya, oo la yidhaahdo aqbasho tirinta. Waxaa badala ay isostoyanie ka dib markii gelitaanka talooyin ah ee signal gacanta kasta count (T).

Sida laga soo xigtay miiska kala guurka ah, sharciga ku saabsan hawlgalka sida flip-Mail waxa lagu tilmaamay by isla'egta sifo: Q (t + 1) = TtQ't V T'tQt. From isla'egta waxaa soo socota in marka codsanaya galo (T) waa macquulka ah eber, ee T flip-flop sii hayn doona xaalka sida unit saarka garaaca wadnaha beddeli.

Shaxda waxa ay muujineysaa in T-flip-flop qabata hawlgalka dheer, iyo tan keentay in horyaalka ee tirinta keebka this, ay macluumaadka (T) aqbasho aqbasho-tirinta. Heerka signal at talooyin ah ee soo dusiyey jeer u muuqataa sida inta badan ay wax soo saarka (Q). Iyadoo la raacayo, ee T-flip-flop loo isticmaalaa sida qaybiye inta jeer ah.

nooca asynchronous T-keeb la dhisey kara oo ku salaysan Rs laba-yada ku dhajisan-flop la xiriir dheeraad ah, kuwaas oo: saarka keebka (Q) waa in la xiran talooyin ah (R), iyo wax soo saarka ah (Q) talooyin ah (S). aqbasho Data (T) waxay noqon doontaa talooyin synchronous (C).

Sawirka wuxuu muujinayaa a T-flip-flop. Scheme functional.

In gobolka bilowga ah, talooyin macluumaadka ku dhajisan-flop (R iyo S) quudin heerka macquulka-eber, marka codsatay in ay aqbasho ah ee eber ah macquul counter (T) ayaa dhici lahaa dawlad nuqul joogto ah oo ka mid ah flip-Terres ah flip-flop labaad marka hore, maxaa yeelay, IYO-NO element soo saari doonaa macquulka ah mid heer on aqbasho oo ka mid ah flip-flop labaad. Haddii T-flip-flop waa ku jira xaalad ah midnimada, ka dibna gashiga ah (R iyo S) la geeyn doonaa in heerarka eber iyo mid ka mid ah ay u kala horreeyaan. On gelitaanka aqbasho count of signal a horeysay loo siman yahay mid macquul ah, waxaa ku qoran qaybta ugu horeeyay ee waraaq-flop macquulka ah. Dawladdu waxay of waddada tooska-flop labaad aysan waxba ka beddelin, maxaa yeelay heerka eber ka soo saarka ee iridda NAND aan la hor istaagay xaaladiisa. Ka dib markii ay ka saareen talooyin garaaca wadnaha tirinta (T) ayaa lagu wadaa in eber, iyo barta keebka labaad ee macquulka ah mid ka mid ah.

In sawirka T-synchronous kiciya. Scheme functional.

T Synchronous flip-Mail waxaa loo isticmaalaa marka loo baahdo si ay u matalaan isku xigxiga ee macquul ah mid ka mid ah ka iman kara ee aqbasho T flip-flop ah.
