The choyambitsa - ndi maziko digito makina

Choyambitsa - ndi chipangizo chophweka ndi makina yadigito. Iwo ali awiri bata boma. Mmodzi wa iwo anayamba "1", ndi wina - "0". Choyambitsa chikhalidwe, ndi mtengo mfundo bayinare amene kusungidwa mmenemo, ndi chizindikiro linanena bungwe anatsimikiza: Direct ndi kukalowa. Ngati linanena bungwe mwachindunji ali ndi kuthekera lolingana ndi mfundo imodzi, ndiye ngati boma amatchedwa choyambitsa Unit (ndi kukalowa chizindikiro mlingo pa linanena bungwe limafanana ndi nkhani ziro). Ngati nyumba si ndi udindo ngati chipangizo amatchedwa ziro.

Choyambitsa Mitundu. Gawo

1. Malinga ndi njira zambiri kujambula zimatulutsa asynchronous ndi synchronous akapsa. Mu zipangizo asynchronous kusinthitsa kumachitika pamene kulowa deta zizindikiro zolowetsa lapansi. Mu Kuwonjezera synchronous kuti mudziwe zofunika, pali ulamuliro zolowetsa (mmodzi kapena angapo). akapsa ndi anazimitsa pamene ntchito kwa zizindikiro kulamulira.
2. Mu kufanizira kwa chipangizo kulamulidwa ndi zomwe zowerengera amagawidwa wodalirika limodzi ndi multistage. Mfundo ntchito pamene choyambitsa akulamulira zowerengera kusintha chipangizo ndi athandizira mlingo chizindikiro kwa zolowetsa deta ndi ulamuliro wamphamvu - kusintha mu Zoyenereza ntchito kwa zolowetsa wa chipangizo michenga yopangira zida zamagetsi. zipangizo Single-siteji ndi ulamuliro siteji, awiri gawo - awiri. synchronous mtundu ndi umodzi akapsa kuloweza nkhani wotchedwa lokhala ndi mkombero, motero, ndi kulowa awiri gawo - awiri sitiroko.
3. Malinga ndi mtundu wa kuzindikira kugwirizana zomveka olekanitsidwa JK-pepala-kulephera, RS-akapsa, T-pepala-kulephera, D-pepala-kulephera ndi zipangizo za mitundu ina.

Magawo waukulu mitundu yonse ya akapsa ndi pazipita athandizira mbendera nthawi, akuchedwa nthawi wofunikila chipangizo kusinthitsa ndi kulola ntchito nthawi.

Kusonyeza mitundu ya zolowetsa choyambitsa

• R - zikutanthauza osiyana athandizira chipangizo anaika mu boma ziro.
• S - chipangizo kusinthitsa mu mode limodzi.
• K - polowera nawo choyambitsa kolowera paliponse ziro.
• J - zikutanthauza osiyana kusinthitsa michenga yopangira zida zamagetsi chipangizo mu chikhalidwe chimodzi.
• T - kuwerenga chipangizo athandizira.
• D - kusintha mode choyambitsa athandizira, kubwereza mlingo athandizira.
• C - synchronizing chipangizo athandizira.
• V - kulamulira, kuwapangitsa athandizira.

The mitundu ikuluikulu ya akapsa

1. Asynchronous RS-pepala-kulephera. chipangizo chimenechi ali limati awiri khola ndi zolowetsa awiri - R ndi S.
2. T-choyambitsa - mtundu yotchuka kwambiri ya zipangizo michenga yopangira zida zamagetsi, iwo ali mmodzi yekha mudziwe (T) athandizira, koma iwo akutchedwa schetnym.Sinhronny RS-pepala-kulephera ali ndi ulamuliro zina (C) athandizira.
3. D-pepala-kulephera. Zipangizo za mtundu uwu m'modzi deta (D) athandizira ndipo akuimira nthawi yomweyo.
4. Nkhanza za m'banja-choyambitsa - Ndipotu, yemweyo D-pepala-kulephera, koma kukhala ndi zina (V) kulamulira athandizira.
5. JK-pepala-kulephera. Mtundu wa chipangizo isiyana asynchronous mu mtengo wa sali RS-mtundu ma chipangizo ndi kukalowa mudziwe kusungidwa.
