RS-flip-गर्नुहोस् qalela. Umgaqo yokusebenza, imizobo ezisebenzayo, itheyibhile yenguqu

Ukuqala - isixhobo elula umatshini wedijithali. It has uzinzo ezimbini karhulumente. Enye yezi meko unikwe ixabiso "1", kunye nezinye - "0". imeko senyanga, kwaye ixabiso ulwazi yokubini igcinwa khona, iziganeko imveliso ixhomekeke: ngqo zocaphulo. Kwimeko apho amandla output ngqo lusekiwe, ongqamana ukulandelelana enye, imeko flip-गर्नुहोस् qalela kuthiwa unit (amandla kwi imveliso zocaphulo ngu 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-Triger, D-flip-गर्नुहोस् qalela kunye nezinye iintlobo-ntlobo).

Ipharamitha ezingundoqo zonke iintlobo eyenza ezi ixabiso likhulu ubude uphawu igalelo, ixesha ulibaziso efunekayo wayicima Flip-गर्नुहोस् qalela, kwaye sivumele ixesha nokusebenza.

Kweli nqaku, makhe sithethe ngale hlobo yesixhobo, njengoko RS-flip-गर्नुहोस् qalela. Bona kweentlobo ezimbini: yolunye kunye emgudu munye.

Olungenangqamaniso RS-flip-गर्नुहोस् qalela na imigca emibini ngendlela eyakhayo (R kunye S) igalelo. Esi sixhobo isebenza ngokungqinelana nale thebhile yenguqu.

Vala loo flip-गर्नुहोस् qalela ludibaniso lwemiqondiso kwi kwizimvo ezinikwe zikomiti ngethuba isixhobo, engunobangela ukungaqiniseki. Oku kudityaniswa ingavezwa njengemfuneko RtSt = 0. Xa ukunciphisa imephu Karnaugh wabonisa ukusebenza komthetho senyanga, ekuthiwa equation iimpawu: Q (t + 1) = St V R'tQt. Ngaloo ndlela RtSt ngu zero.

Kwi mzobo esebenza ibonisa RS-flip-गर्नुहोस् qalela olungenangqamaniso uhlobo NAND kunye nokusebenza yesibini NOR iziqalelo.

Uhlobo lwesibini - yolunye RS-FF. Loo isixhobo ngokokwakheka na igalelo ngqo S ezintathu, R, kunye C. Umahluko phakathi yolunye kunye olungenangqamaniso uhlobo flip-गर्नुहोस् qalela kuba phambi igalelo sokuGcina ungqamaniso (C). Kuyimfuneko ngenxa yezi zizathu zilandelayo: ngokuba segalelo yifowuni (logic element) iimpawu bathunyelwa akusoloko ngexesha elinye. Oku kungenxa yokuba kugqitha iintlobo kunye nenani nodes ukuba babe ulibaziseko ezahlukeneyo ezahlukeneyo. Le nto ibizwa ngokuba "umdlalo." Ngenxa "iziganeko" ezinjalo amaxabiso uphawu efunyenweyo iya enyanzeliswa phezu amaxabiso ezidlulileyo ezinye iziganeko. Konke oku kukhokelela izixhobo alarm lobuxoki.

Lo mkhwa lupheliswe ngokusebenzisa igalelo amaza isixhobo ngezisombululo. Ezizezi, i-logic element ulwazi input Imiqondiso ngaphandle kwabo bakhonza ngqo pulses ezingundoqo ukuvumelanisa, eli xesha ulwazi input iimpawu ixesha ukutshixa akhwele igalelo.

Imeko esingundoqo ukusebenza oluchanekileyo yokutshintsha amanqanaba logic kwi RS-flip-गर्नुहोस् qalela kunye logic ezilawulwa zizo - RT ukungamkeleki inyathelo ngaxeshanye okanye uphawu St, isixhobo ziguquka, kunye nolwazi retrieval evela imveliso Q (t + 1) amabini ध्यानाकर्षण. Kulo mba, la manqaku okunokwenzeka oqulethe izinto kuphela yolunye.

RS-uhlobo flip-गर्नुहोस् qalela iimpawu yolunye kumelwa equation: Q (t + 1) = StCt V R'tQt V QtC't.

Le ifoto ibonisa RS-adubule uhlobo yolunye NAND. Input KUNYE amasango, HAYI iyunithi ngokwengqiqo idluliselwe data utshintshe nje igalelo S okanye R ukuba amagalelo kuyimfuneko RS olungenangqamaniso ungachwetheza Kwasika esiswini kunye igalelo wakhona kuphela xa ngegalelo yolunye (C) uphawu kwi logic enye.
