Molao-motheo o Sebetsang oa Lipotoloho tsa Flip-flop
Pendahuluan
Disekete tsa Flip-flop ke e 'ngoe ea litene tsa motheo tsa lisebelisoa tsa elektroniki tsa dijithale, tse nolofalletsang polokelo le ts'ebetso ea tlhahisoleseling ea binary (li-bits). Li-flip-flop li tla ka mefuta e mengata 'me li na le mefuta e mengata ea lits'ebetso, ho tloha polokelong ea data ho isa ho lisekete tse rarahaneng tsa logic. Sengoloa sena se ikemiselitse ho teba ka ho teba melao-motheong ea ts'ebetso ea li-flip-flop, mefuta e fapaneng, le ts'ebeliso ea tsona lisebelisoa tsa elektroniki.
Melao-motheo ea Motheo ea Mosebetsi
Flip-flop ha e le hantle ke potoloho e nang le bistable, ho bolelang hore e ka ba teng ho e 'ngoe ea maemo a mabeli a tsitsitseng. Potoloho ena e khona ho boloka maemo ana ntle le tlhoko ea lets'oao le tsoelang pele la ho kenya. Ho fapana le liheke tse bonolo tsa logic, tse fetolang tlhahiso ea tsona hang-hang ho latela tlhahiso, flip-flop e ka "hopola" boemo ba eona ba ho qetela.
SR Flip-flop
Mofuta o bonolo ka ho fetisisa oa flip-flop ke flip-flop ea SR (Set-Reset). Likarolo tse ka sehloohong tsa flip-flop ea SR ke liheke tse peli tse hokahaneng tsa NOR kapa NAND. Mona ke tafole ea 'nete bakeng sa flip-flop ea SR e sebelisang liheke tsa NOR:
| S (Sete) | R (Seta Botjha) | Q (Sehlahiswa) | Q' (Tlatsetso ya Sehlahiswa) |
|————|————–|————|————————|
| 0 | 0 | Q (e fetileng) | Q' (e fetileng) |
| 0 | 1 | 0 | 1 |
| 1 | 0 | 1 | 0 |
| 1 | 1 | E sa Hlalosoang| E sa Hlalosoang |
Boemo bo tafoleng moo S le R ka bobeli e leng 1 ke boemo bo sa tsitsang 'me ha bo sebelisoe ts'ebetsong.
D Flip-flop
Ho rarolla bothata ba boemo bo thibetsoeng ho SR flip-flops, ho ile ha hlahisoa D flip-flop. D flip-flop e nolofatsa tlhahiso ka ho ba le data input e le 'ngoe feela (D) le oache input e le 'ngoe (C). Tlhahiso e tla fetola boemo feela ha lets'oao la oache le le teng. Mona ke tafole ea 'nete bakeng sa D flip-flop:
| D | Oache | Q (Sehlahisoa) | Q' (Tlatsetso ea Sehlahisoa) |
|—|——-|—————|————————|
| 0 | ↑ | 0 | 1 |
| 1 | ↑ | 1 | 0 |
Ha ntlha e nyolohang ya letshwao la oache e hlaha, tlhahiso ya Q e tla latela boleng ba D.
JK Flip-flop
JK flip-flop ke ntlafatso e 'ngoe ho SR flip-flop, e felisang boemo bona bo sa tsitsang. JK flip-flop e na le li-input tse peli, J le K, le oache e kenang. Tafole ea eona ea 'nete ke e latelang:
| J | K | Oache | Q (Sehlahisoa) | Q' (Tlatsetso ea Sehlahisoa) |
|——|——|——-|—————|————————|
| 0 | 0 | ↑ | Q (e fetileng) | Q' (e fetileng) |
| 0 | 1 | ↑ | 0 | 1 |
| 1 | 0 | ↑ | 1 | 0 |
| 1 | 1 | ↑ | Q' (e fetileng) | Q (e fetileng) |
Ha di-input J le K e le 1, tlhahiso e tla ba tlatsetso ya boemo bo fetileng, kapa ka mantswe a botekgeniki "toggle".
T Flip-flop
Flip-flop ea T kapa Toggle flip-flop ke mofuta oa JK flip-flop moo li-input ka bobeli J le K li hokahaneng 'moho 'me li ngoloa T. Sena se etsa hore tlhahiso ea Q e fetole boemo nako le nako ha ho na le moeli oa lets'oao la oache. Tafole ea 'nete e tjena:
| T | Oache | Q (Sehlahisoa) | Q' (Tlatsetso ea Sehlahisoa) |
|—|——-|—————|————————|
| 0 | ↑ | Q (e fetileng) | Q' (e fetileng) |
| 1 | ↑ | Q' (e fetileng) | Q (e fetileng) |
Ho Kenngwa Tshebetsong le Tshebediso
Lingoliso le Memori
E 'ngoe ea lits'ebetso tsa mantlha tsa li-flip-flop e ho li-registers le memori. Register ke pokello ea li-flip-flop tse bolokang likotoana tsa data; hangata, flip-flop e le 'ngoe e boloka bit e le 'ngoe. Li-registers li sebelisoa haholo ho li-microprocessor ho boloka data e ntseng e sebetsoa ka nakoana. Ka ho hokahanya li-flip-flops tse ngata, re ka theha rejista e nang le bophara bo itseng ba bit, mohlala, 8-bit kapa 16-bit.
Memori ea khomphutha e kang SRAM (Static RAM) e na le matrix e kholo ea li-flip-flop tse ka fihlellehang ho bala kapa ho ngola data.
Sehatsetsi le Sekhao-nako
Li-flip-flop li boetse li sebelisoa lipotolohong tsa counter le timer. Khaontara ke potoloho e balang lets'oao la oache ebe e le fetola sebopeho sa binary, se ka sebelisoang bakeng sa nako kapa e le index. Mohlala o bonolo ke ho sebelisa li-flip-flop tsa T ka tatellano ho theha khaontara ea binary.
Shift Register
Rejistara ya diphetoho ke mofuta wa rejistara e ka fetolang di-data bits tsa yona ka ho le letshehadi kapa ka ho le letona. E sebediswa ditshebedisong tse fapaneng, tse kang ts'ebetso ya data ya serial-to-parallel, moo data e serialized kapa e bapiswang bakeng sa ho romela kapa ho amohela ho tswa tsamaisong.
Molaoli oa Logic
Ka lebaka la tlhaho ea ho boloka boemo ba li-flip-flop, li sebelisoa ho balaoli ba logic ho latela boemo kapa phetoho ea potoloho e thehiloeng liketsahalong tsa ho kenya. Mohlala ke mochini oa boemo, o etsang ts'ebetso e itseng ho latela boemo ba oona ba hona joale le lets'oao la ho kenya leo o le fumanang.
Qetello
Li-flip-flop ke karolo ea bohlokoa lipotolohong tsa elektroniki tsa dijithale. Ka mefuta e fapaneng ea li-flip-flop, tse kang SR, D, JK, le T, re ka finyella mefuta e mengata ea mesebetsi le lits'ebetso, ho tloha polokelong e bonolo ea data ho isa taolong e rarahaneng ea logic. Ho utloisisa melao-motheo ea ts'ebetso ea li-flip-flop le lits'ebetso tsa tsona ho re lumella ho rala litsamaiso tsa dijithale tse sebetsang hantle le tse sebetsang hantle ho latela litlhoko tsa rona. Jwalo ka e 'ngoe ea litene tsa mantlha lefatšeng la lisebelisoa tsa elektroniki, li-flip-flop li tla lula e le karolo ea bohlokoa mekhoeng ea theknoloji ea nakong e tlang.
