T mungaimitse-phidigu. Mfundo ntchito, dera zinchito

Hule - chipangizo chophweka ndi makina yadigito. Iwo ali limati awiri wokhazikika. Chimodzi mwa zinthu izi akapatsidwa mtengo "1" ndi zina "0". udindo chipangizo, ndi mtengo mfundo bayinare amene kusungidwa mmenemo, ndi chizindikiro linanena bungwe anatsimikiza: Direct ndi kukalowa. Ngati kumene mwachindunji angathe linanena bungwe udzakhazikitsidwe womwe ndi mfundo imodzi, ndiye boma la pepala-kulephera otchedwa unit (kuthekera pa linanena bungwe kukalowa limafanana ndi nkhani ziro). Ngati linanena bungwe mwachindunji si kuthekera, ndiye chikhalidwe choyambitsa amatchedwa ziro.

Akapsa anawagawira ndi mbali zotsatirazi:

1. Ndi njira kungosunga zomwe tamva (synchronous ndi asynchronous).

2. Mogwiritsa ntchito mfundo ulamuliro (ziwerengero zazikulu, osakwatira gawo, multistage).

3. Ndi njira ya kukwaniritsidwa kwa kugwirizana zomveka (JK-pepala-kulephera, RS-akapsa T mungaimitse-phidigu, D-pepala-kulephera ndi zina).

Magawo waukulu mitundu yonse ya akapsa ndi: pazipita nthawi ya chizindikiro athandizira, akuchedwa nthawi wofunikila kusintha pa pepala-kulephera, ndi kulola ntchito nthawi.

M'nkhani ino, tiyeni tikambirane za mtundu wa chipangizo, mmene - T pepala-kulephera. akapsa oterowo yekha mfundo imodzi (T) athandizira, ndilo lotchedwa ochuluka athandizira. Chingasinthe isostoyanie pambuyo chikuonetseratu kuti tawerenga (T) Muzifunsa wina chizindikiro kulamulira.

Malinga tebulo kusintha lamulo la ntchito ngati pepala-phidigu anafotokozedwa ndi aone kuti pali khalidwe: Q (T + 1) = TtQ't V T'tQt. Kuyambira aone kuti pali izo motere Pamene ntchito polowera (T) ndi mfundo ziro, ndi T pepala-kulephera adzakhala nawobe udindo wake ngati amodzi zimachitika linanena bungwe anyamata.

Tebulo limasonyeza kuti T-pepala-kulephera amachita Kuwonjezera opareshoni, ndipo izi zinachititsa kuti mutu wa choyambitsa izi ochuluka, mfundo zake (T) athandizira-ochuluka athandizira. Mlingo chizindikiro pa Muzifunsa latch pamaoneka kawiri nthawi kusiyana ndi linanena bungwe ake (Q). Motero, T-pepala-kulephera ntchito ngati pafupipafupi wogawira.

T-choyambitsa mtundu asynchronous akhoza inamangidwa zochokera RS awiri gawo mungaimitse-phidigu ndi kugwirizana zina, akuti: ndi choyambitsa linanena bungwe (Q) ayenera olumikizidwa kwa athandizira (R), ndipo linanena bungwe (Q ') ndi athandizira (S). Data athandizira (T) adzakhala synchronous athandizira (C).

The chithunzi limasonyeza T-pepala-kulephera. Chiwembu zinchito.

Mu boma koyamba, athandizira mudziwe mungaimitse-phidigu (R ndi S) kudyetsedwa mlingo mfundo-ziro, pamene ntchito kwa kauntala (T) Muzifunsa ziro zomveka kudzachitika mpaka kalekale buku boma la woyamba pepala-kuwuluka yachiwiri pepala-kulephera, chifukwa ndi NO mchitidwe chimatulutsa mfundo mlingo umodzi pa Muzifunsa wachiwiri pepala-kulephera. Ngati T-pepala-kulephera ndi mu mkhalidwe umodzi, ndiye zolowetsa (R ndi S) adzakhala atapereka kwa kuchuluka kwa ziro ndi munthu winayo. Pa chikuonetseratu kuti tawerenga Muzifunsa chizindikiro choyamba wofanana zomveka wina, zinalembedwa mu choyamba pepala-kulephera mfundo unit. Boma la wachiwiri pepala-kulephera sasintha, chifukwa mlingo wa ziro ku linanena bungwe la NAND chipata si watsekedwa ndi chikhalidwe chake. Pambuyo kuchotsa ochuluka zimachitika athandizira (T) amamasulidwa ku ziro, ndipo chachiwiri choyambitsa masiwichi kwa mfundo imodzi.

Mu chithunzi T-synchronous choyambitsa. Chiwembu zinchito.

Synchronous T pepala-phidigu ntchito ngati pakufunika kutero amaimira ndondomeko ya zomveka angathe wina pa athandizira T pepala-kulephera.
