I-AM1808EZWT3 Eyangempela Futhi Entsha Ngenani Elincintisanayo Kumhlinzeki we-IC Wesitokwe

I-microprocessor engu-16-bit ingahlukaniswa ibe izingxenye ezimbili, ingxenye eyodwa iyunithi yokubulala (EU), okuyingxenye eyenza imiyalelo;enye ingxenye iyunithi yesixhumi esibonakalayo sebhasi (BIU), exhunywe ebhasini le-8086 futhi lenze umsebenzi wokulanda imiyalelo kumemori.Ngemuva kokuthi i-microprocessor ihlukaniswe yaba yi-EU ne-BIU, imisebenzi yokulanda imiyalelo nemiyalo yokwenza ingagqitshwa.Ingxenye ye-EU inefayela lokubhalisa, eliqukethe amarejista ayi-8 16-bit, angasetshenziswa ukugcina idatha, inkomba kanye ne-stack pointer, i-arithmetic operation logic unit (ALU) ukwenza imisebenzi ye-arithmetic kanye nokusebenza okunengqondo, namarejista amafulegi okumele agcinwe. izimo zemiphumela yale misebenzi.Lawa mayunithi eyunithi yokusebenza adlulisa idatha ngebhasi ledatha.Iyunithi yesixhumi esibonakalayo sebhasi nayo inefayela lerejista, lapho i-CS, DS, SS, ne-ES kuyirejista yengxenye yokuhlukaniswa kwesikhala sememori.I-IP iyisikhombi semiyalo.Irejista yokuxhumana kwangaphakathi nayo iyirejista yokugcina imininingwane okwesikhashana.Ulayini womyalo uwukugcina umyalo olandwe ngaphambilini.Ingxenye yesixhumi esibonakalayo sebhasi nayo ine-adder yekheli, eyengeza inani lerejista yengxenye kanye nevelu ye-offset ukuze uthole ikheli lendawo le-20-bit.Idatha namakheli axhunywe nebhasi lesistimu ye-8086 yangaphandle ngokusebenzisa i-logic yokulawula ibhasi.I-8086 inebhasi yedatha engu-16-bit.Lapho iphrosesa kanye ne-off-chip kudlulisa idatha, inombolo kanambambili engu-16-bit idluliselwa ekilasini elilodwa.I-8086 inokwakheka kwepayipi okuyinhloko, engabona ukugqagqana kokusebenza kwe-on-chip nokusebenza kwe-off-chip.
