Nooca Wareegga Isku-dhafan
Microprocessor-ka 16-bit ah waxa loo qaybin karaa laba qaybood, qayb waa unugga fulinta (EU), oo ah qaybta fulinaysa tilmaamaha;Qaybta kale waa unugga is dhexgalka baska (BIU), kaas oo ku xidhan baska 8086 oo fulinaya hawlgalka habaynta tilmaamaha ee xusuusta.Ka dib marka microprocessor-ku u qaybsamo EU iyo BIU, hawlgallada keenista tilmaamaha iyo fulinta tilmaamaha waa la isku dhejin karaa.Qaybta EU-da waxay leedahay faylka diiwaanka, kaas oo ka kooban 8 diiwaanka 16-bit, kaas oo loo isticmaali karo in lagu kaydiyo xogta, index iyo stack pointer, unit logic operation arithmetic (ALU) si loo fuliyo hawlaha xisaabinta iyo hawlgallada macquulka ah, iyo diiwaanka calanka si loo kaydiyo. shuruudaha natiijooyinka hawlgalladan.Cutubyadan ku jira qaybta fulinta waxay xogta ku wareejiyaan baska xogta.Unugga is-dhexgalka baska waxa kale oo uu leeyahay faylka diiwaanka, halkaas oo CS, DS, SS, iyo ES ay yihiin diiwaanka qaybinta booska xusuusta.IP waa tilmaame tilmaame.Diiwaanka isgaarsiinta gudaha sidoo kale waa diiwaan si ku meel gaar ah loo keydiyo xogta.Safka amarku waa in la kaydiyo socodka tamarta ee horay loo keenay.Qaybta is dhex galka baska waxa kale oo ay leedahay ciwaanka ciwaanka, kaas oo ku daraya qiimaha diwaangalinta qaybta iyo qiima dhimista si loo helo ciwaanka jireed ee 20-bit ah.Xogta iyo ciwaanada waxa lagu xidhay baska nidaamka 8086 ee dibadda iyada oo loo marayo macquulnimada xakamaynta baska.8086 wuxuu leeyahay baska xogta 16-bit ah.Marka processor-ka iyo off-chip-gu ay gudbiyaan xogta, nambarka binary-ga ah ee 16-bit ah ayaa lagu kala qaadaa hal fasal.8086 waxa ay leedahay qaab-dhismeedka dhuumaha aasaasiga ah, kaas oo xaqiijin kara isku-dhafka hawlgallada on-chip-ka iyo hawlgallada ka baxsan-chip-ka.
