I-AM1808EZWT3 Eyoqobo kwaye iNtsha enexabiso eliKhuphisanayo kwi-Stokhwe ye-IC yoMboneleli

I-16-bit microprocessor inokwahlulwa ibe ngamacandelo amabini, enye inxalenye yiyunithi yokubulawa (EU), eyona nxalenye eyenza imiyalelo;enye inxalenye yiyunithi yojongano lwebhasi (BIU), edityaniswe kwibhasi ye-8086 kwaye iqhube umsebenzi wokulanda imiyalelo kwimemori.Emva kokuba i-microprocessor yahlulwe ibe yi-EU kunye ne-BIU, imisebenzi yokulanda imiyalelo kunye nemiyalelo yokuphumeza inokugqithwa.Inxalenye ye-EU inefayile yerejista, equka iirejista ze-8 ze-16-bit, ezingasetyenziselwa ukugcina idatha, isalathisi kunye ne-stack pointer, i-arithmetic operation logic unit (ALU) ukwenza imisebenzi ye-arithmetic kunye nokusebenza kwengqondo, kunye neerejista zeflegi ukugcina. iimeko zeziphumo zale misebenzi.Ezi yunithi kwiyunithi yokuphumeza idatha yokudlulisa idatha ngebhasi yedatha.Iyunithi ye-bus interface nayo inefayile yerejista, apho i-CS, i-DS, i-SS, kunye ne-ES ziirejista zecandelo lokwahlulahlula indawo yememori.IP isalathiso somyalelo.Irejista yonxibelelwano lwangaphakathi ikwayirejista yokugcina idatha okwethutyana.Umgca womyalelo kukugcina umyalelo olandwe kwangaphambili.Inxalenye ye-bus interface nayo ine-adder yedilesi, eyongeza ixabiso lerejista yecandelo kunye nexabiso le-offset ukufumana idilesi ye-20-bit.Idatha kunye needilesi zidityaniswe nenkqubo yebhasi ye-8086 yangaphandle ngengqiqo yolawulo lwebhasi.I-8086 inebhasi yedatha ye-16-bit.Xa iprosesa kunye ne-off-chip ihambisa idatha, inani le-binary ye-16-bit lihanjiswa kwiklasi enye.I-8086 inokwakhiwa kombhobho osisiseko, onokuqonda ukugqithelana kwemisebenzi ye-on-chip kunye nokusebenza kwe-off-chip.
