D-rukungiso: yacho uchishandisa pfungwa, tafura chokwadi

Rukungiso - imwe chepuraimari chikwata vanoumba digital otomatiki maviri-mamiriro pakusimba, mumwe iyo basa kukosha "1", uye mumwe - "0".

Mune nzira kuzadziswa musoro kwokubatana kusiyanisa marudzi anotevera mano: T-pafiripi-chips on whitekuva, D-pafiripi-chips on whitekuva, JK-pafiripi-chips on whitekuva, RS-ude. Chokwadi, pano ndivo rakajairika kusarudza, asi kunze navo pane otomatiki mano uye mamwe marudzi.

Munyaya ino, isu kunyatsotarisisa panguva D-rukungiso. Akati muchina ane mashoko chete (D) chiyamuro, naizvozvo, Mwari akaronga kushandisa nguva kunonoka chaitika.

The maitiro mukana wokuti vanhu vanga Q _{(T + 1)} = DT anorondedzera kushanda kwaiita mudziyo akadai D-pafiripi-chips on whitekuva. The tafura chokwadi (Table kuchinja) ichi hurumende muchina unoratidzwa pazasi.

Sezvo tinogona kuona, ari wokutanga mutsetse rechina tsika Q anonongedzera panguva T uye T + 1 rienderane. Kureva D-pafiripi-chips on whitekuva ndicho chiratidzo kunonoka Kufananidzira. Somugumisiro pakati asynchronous mhando kutofunga mano hadzina kuwanikwa chikumbiro chavo, sezvo goho kudzokorora mazano Mureza duku nguva yokunonoka.

D-mhando pafiripi-chips on whitekuva inovakwa pamusoro synchronous chete-pamwero (chete-dariro) uye duplex (mbiri-Danho) RS-mano chete mhando. Michina operam maererano tafura iitike.

Single-Danho D-pafiripi-chips on whitekuva anogona configured kubva chete paiva synchronous RS-midziyo uye mumwe UYE-HE1, izvo richibatanidza zvakafanana mashoko (D) mazano mbiri D-Ivan Kuchin chiyamuro rukungiso.

At okutambirwa imwe pfungwa razero pamusoro wachi chiyamuro RS mhando otomatiki pfungwa-imwe pamwero akarwiswa chete zvine maatomu akafanana outputs UYE-NO ₂ uye UYE-NO _3. Kana kuchinja sync chiratidzo pamwero kureva mashoko chiyamuro, kana anosika inonzwisisika razero pa mazano S (pana D = 1) kana mazano R (pamwe D = 0) ari asynchronous rukungiso T. Richaita chinja kuti hurumende chaienzanirana musoro padanho D. Single- D-mhando pafiripi-chips on whitekuva rinononotsa mashoko mazano ari kumbomira pakati synchronizing anonongedzera.

D-pafiripi-chips on whitekuva pamwe vakagwinya kuzvidzora. Job Description, dzichipfekeka dhayagiramu

Automatic umhare ichi mhando inovakwa nhatu RS-rukungiso asynchronous mhando. Vari kwakavakirwa NAND, vaviri kuita nokuchinja basa, uye wechitatu ari goho. The outputs of nokuchinja rukungiso zvakagadzirirwa kudzora goho rukungiso.

Kana padanho chiratidzo C yakaenzana inonzwisisika zero, kuti goho mumwe chikungiso zvinoshandisa pakurima yaipiwa kwairi kwazvakarerekera chiratidzo mubatanidzwa, uye kuitwa kuchengetera muoti. Kana kuchinja mashoko chiratidzo nokuchinja kunokonzera mu hope muoti, uye chiratidzo ndiyo mazano kuti vakwanise pfungwa imwe rukungiso chiyamuro C, iyo goho pamusoro automaton yakaiswa itsva pakusava iyo unoenderana mashoko chiratidzo pamusoro D-mazano muzvirevo kutenderera.

In Kana apo mashoko chiratidzo pamwero shanduko kuchaitika munguva kugadzwa goho rukungiso chiratidzo kana nokuchinja mudziyo asingadi kupfuura. Zvakaratidza kuti chinangwa nokuchinja rukungiso ndiyo negashiro mashoko anonongedzera, uchatamisa navo goho mudziyo nenguva chiyamuro shanduko chiratidzo panguva nokudzora chiyamuro C kubva pfungwa razero mumwe pfungwa imwe latching chiratidzo kubva inofambiswa ruzivo chiyamuro.
