T amabini ध्यानाकर्षण. Umgaqo ukusebenza, wesiphaluka ukusebenza

Ukuqala - isixhobo elula umatshini wedijithali. It has ithi ezimbini uzinzo. Enye yezi meko unikwe ixabiso "1" kunye nezinye "0". isimo Device, kwaye ixabiso ulwazi yokubini igcinwa khona, iziganeko imveliso ixhomekeke: ngqo zocaphulo. Kwimeko apho amandla output ngqo lusekiwe, ongqamana ukulandelelana enye, ngoko ke imeko flip-गर्नुहोस् qalela kuthiwa unit (amandla kwi imveliso zocaphulo lihambisana ubhalo zero). Ukuba imveliso ngqo ayikho ezinokubakho, ngoko ke imeko aqala kuthiwa zero.

Ukuqaleka zihlelwa yi ezi mpawu zilandelayo:

1. Xa indlela zokurekhodisha ulwazi (yolunye kunye olungenangqamaniso).

2. Xa indlela ingcaciso yolawulo (manani, onamandla, single-yeqonga, multistage).

3. Xa indlela ukubonwa unxulumano ubhalo (JK-flip-गर्नुहोस् qalela, RS-ichukumisa T amabini ध्यानाकर्षण, D-flip-गर्नुहोस् qalela kunye nezinye iintlobo-ntlobo).

Ipharamitha ezingundoqo zonke iintlobo eyenza zezi: ubude iphezulu uphawu igalelo, ixesha ulibaziso efunekayo wayicima flip-गर्नुहोस् qalela, kwaye sivumele ixesha nokusebenza.

Kweli nqaku, makhe sithethe ngale hlobo yesixhobo, njani - T flip-गर्नुहोस् qalela. ezingabangela abanjalo ulwazi omnye (T) igalelo kuphela, ekuthiwa igalelo ukubala. Itshintsha isostoyanie yayo emva ukwamkelwa ubalo (T) igalelo isiginali yolawulo nganye.

Ngokutsho etafileni lenguqu, umthetho ukusebenza loo flip-flops sichazwa equation iimpawu: Q (t + 1) = TtQ't V T'tQt. Ukusuka equation kulandela ukuba xa isicelo zokungena (T) ukulandelelana zero, esi T flip-गर्नुहोस् qalela baligcine ubume bayo njengeyunithi ukubetha yemveliso ingene.

Le theyibhile ibonisa ukuba T-flip-गर्नुहोस् qalela owenza umsebenzi Ukongezelela, kwaye oku kukhokelele kwisihloko le ukubalwa senyanga, ingcaciso yaso (T) igalelo-ukubala igalelo. Inqanaba uphawu kwi igalelo kwikroba ivela ngokuphindwe kaninzi ngaphezu kwi output kwayo (Q). Ngako oko, i T-flip-गर्नुहोस् qalela esetyenziswa njenge ehlukanisayo rhoqo.

T-ibangelwe uhlobo olungenangqamaniso unako kwakhiwa ngokusekelwe RS yeqonga-ezimbini kumacala amabini ध्यानाकर्षण ihlangene ezongezelelweyo, ezizezi: imveliso aqala (Q) kufuneka adityaniswe input (R), kunye output (Q ') kunye igalelo (S). input Data (T) iya kuba igalelo yolunye (C).

Lo mfanekiso ubonisa T-flip-गर्नुहोस् qalela. Scheme esebenza.

In isimo sokuqala, le igalelo ulwazi amabini ध्यानाकर्षण (R kunye S) wondla kwinqanaba logic-zero, xa isicelo kwi-counter (T) igalelo lwe zero sengqiqweni kubakho esisigxina ikopi imo lokuqala flip-kaFosbury yesibini Flip-गर्नुहोस् qalela, kuba AND-NO Ingxenye kuvelisa logic kwinqanaba elinye ku igalelo lesibini flip-गर्नुहोस् qalela. Ukuba T-flip-गर्नुहोस् qalela sikwimo womanyano, ngoko ke amagalelo (R kunye S) ziya kunikwa kumanqanaba zero enye ngokulandelelanayo. Kwi sokwamkelwa ubalo igalelo uphawu yokuqala elingana eyodwa kuphela enengqondo, ebhaliweyo iyunithi logic flip-गर्नुहोस् qalela yokuqala. Isimo sesibini flip-गर्नुहोस् qalela ayitshintshi, kuba umgangatho zero ukusuka we NAND isango akuxhomekekanga ivalwe imeko yakhe. Emva kokuba igalelo ukubala ukubetha (T) isetwe ku-zero, kunye itshintshela abangela lesibini logic omnye.

Kwifoto T-yolunye adubule. Scheme esebenza.

T yolunye flip-flops asetyenziswa xa kuyimfuneko ukubonisa ulandelelwano enengqondo omnye kho igalelo T flip-गर्नुहोस् qalela.
