Taketake rorohiko Logic

Tetahi pūrere ranei tikanga hanga e te tangata, i runga i nga ture motuhake o tona mahi, e ka tohatoha ai i roto i nga āhuatanga tono me te taumahinga. Ko te hiahia ki te whakatau i te hiahia akiaki ko te faaitoitoraa matua mo te whanaketanga o ngā momo hou o mihini, hangarau, me ētahi atu hanga ana tēnei te taea te haaputuputuraa o te matauranga i roto i te maha ngā wāhi o te pūtaiao me te hangarau, te whakamahi o e taea ai ki a koe te hanga i tētahi whare arorau tuatahi wāhi hou o te hangarau, pērā i te turanga arorau o te rorohiko, a ka iriti i ratou ki momo hou o taputapu. Kei te tuku te reo tangata Simple ki rite "te ahunga whakamua hangarau".

Ko te pana o te putanga o rorohiko e rua taumu'a peia: te hiahia hoki buka nui o tukatuka mōhiohio me te whakatutukitanga i roto i mara ngā o te pūtaiao me te hangarau (hiko, pāngarau, te ahupūngao me te hangarau o Semiconductors, konganuku me te tini ke atu). Ko te tauira tuatahi o te rorohiko hiko whakapumautia whakaaro te mau parau tumu o te rorohiko, ka tīmata te tau o te whanaketanga tere o te piha haapiiraa hou o ngā hangarau, ka karanga "rorohiko hiko".

i whakatakoto hoki i te whakatinanatanga o te whakaaro hangarau o nga taketake rorohiko arorau pūrere rorohiko mā te whakamahi i te taurangi o arorau, te tautuhi i te huinga o ngā āhuatanga, me te pūtake ariā. ture Boolean e tautuhi nga turanga arorau o te rorohiko, whakatakoto i roto i te rau tau 19 Ingarihi Hoani. Bull. I roto i te meka, ko reira te pūtake ariā o ngā pūnaha mamati o tukatuka mōhiohio. kėia ko tōna ngako nga ture o whanaunga arorau i waenganui i te tau: i te taha, disjunction me te tahi atu, i te mea tino rite ki te hononga pai-mohiotia taketake i waenganui i te tau i roto i te tauhanga - whakareatanga, tua, me ētahi atu Ko te tau i roto i te taurangi Boolean ko te kanohi-rua, arā, kanohi anake i roto i te whika 1 me 0. nga mahi e whakaahuatia ki tau o Boolean atu tohu. Ēnei āhuatanga tukua te huinga o pāngarau ture arorau timatanga whakaahua i tetahi raruraru tātai he mahi mana e tohu motuhake ranei, e ko, "ki te tuhituhi i tētahi hōtaka." Mā te whakamahi i te pūrere tāuru, he "utaina" ki te rorohiko tenei hōtaka, me te tavini rite he "tukunga" mo ki kia whakamana ai.

pūrere Tāuru faafariu tohu taumai ki tohu hiko rite te waehere pūtakerua, me nga ngā mahi ki runga ki a ratou - whakamua, me te tahuri te ite mahi tauhanga me e whakamana ngā mahi arorau e ngā pūrere hiko i huaina kuwaha, neke, pore-flops etc. Ua riro raua na te hau hangarau te rorohiko, te wahi tatau ratou i roto i nga tekau o nga mano o ngā tūemi.

Te hanga Kei roto te rorohiko matua kōwae 4: CU - wae mana, he RAM me te ROM - mahara kōpuku me te rokiroki kaha, te ALU - wae arorau tauhanga, IOCTL - e te pūrere tāuru. O te akoranga, ia o ratou i roto i te hanganga ture i te hoahoa o nga turanga arorau o te rorohiko. tukanga rorohiko Work ngā utanga ki RAM ROM whakahaere ranei hōtaka, te tuhituhi i roto i nga tikanga motuhake, kei te rongoa i runga i ngā kāri weropepahia, rïpene autō, kōpae autō, me te whatu, me ētahi atu pāpāho. Kei te hangaia tēnei hōtaka mō te whawhe uu rerenga o nāianei ranei mōhiohio mahi, me te whiwhi i te hua programmed, hei tauira, te whakaatu i te whakapakoko i runga i te aroturuki i te faafariuraa tohu oro mamati ranei, me ētahi atu Ki tenei mutunga, mahi CU whakawhitinga maha o poraka mōhiohio i waenganui i nga whakaaro katoa ngā i roto i te rorohiko.

Ko te matua "pokapū karere" Ko te ALU rorohiko - kaiwhakaari o te tauhanga me katoa ngā mahi arorau. I tēnei wā, mahi te ALU te pūrere mahi i huaina he pūtukatuka microprocessor ranei, i te mea he pūrere Semiconductor te rahi o o matchboxes te tokorua, ki te maha whakaponohia huinga o ngā mahi. Āta tāpiri ki te microprocessor mahi mana o ngā pūrere waho - te aroturuki i, pūreretā, me ētahi atu Kua whakaaetia ngā whanaketanga Tata i roto i tenei rohe ki te waihanga i microprocessors ki te huinga tonu o ngā waeine mahi o rorohiko, na puta ratou rorohiko kotahi-kongakonga me ngā pute-rahi te rorohiko tonu. He aha te mea poitirere ko e te turanga arorau o te rorohiko hangaia kotahi mo te pūrere rorohiko tuatahi, kahore i puta ke ki tenei ra.
