Interruptions and exceptions - in the system or given time at the moment in the matter muayan condition when done appear when the processor intervention is required .
This is the processor being performed current problem to stop and management interruptions again running or exceptions again known as running special procedure or assignment transfer forced reaches _
Interruptions usually optional time moment appear will be . Interruptions hardware and software will be . The first is to him service required to do peripheral devices received hardware signal on yield will be .
Software interruptions INT n instruction using yield will be .
Exceptions - processor internal events - he or this of the guide completion on time somehow wrong conditions signal : to zero _ to be , to protect rules breaking pages _ absence and hk
Interruptions or exceptions happen when being performed current issue again performance being performed time duration automatic stops , hence then his completion duration without losing to be continued reaches only _ delay or exception again performance application to stop forced reaches _
All interruptions and exceptions 0 to 255 which was in the range numbered ( mostly ) they are called vectors ) . 0..31 numbers exceptions Intel company for by to reserve obtained .
Interruptions
Uzilishlar va istisnolar – tizimda yoki berilgan vaqt momentidagi masalada muayan shart bajarilganda paydo bo’lganda, protsessorning aralashuvi talab etiladi.
Bu protsessorni bajarilayotgan joriy masalani to’xtatishga va boshqaruvni uzilishlarni qayta ishlaydigan yoki istisnolarni qayta ishlaydigan deb nomlanuvchi maxsus protsedura yoki topshiriqqa uzatishga majbur etadi.
Uzilishlar odatda ixtiyoriy vaqt momentida paydo bo’ladi. Uzilishlar apparatli va dasturiy bo’ladi. Birinchisi, unga xizmat qilish talab etilgan periferik qurilmalardan olingan apparat signali bo’yicha xosil bo’ladi.
Dasturiy uzilishlar INT n ko’rsatmasi yordamida hosil bo’ladi.
Istisnolar - protsessorning ichki hodisalari – u yoki bu ko’rsatmaning bajarilishi vaqtida qandaydir noto’g’ri shartlar to’g’risida signal berish: nolga bo’lish, ximoya qoidalarini buzish, sahifalarning yo’qligi va h.k.
Uzilishlar yoki istisnolar sodir bo’lganda bajarilayotgan joriy masala qayta ishlash bajarilayotgan vaqti davomiyligida avtomatik to’xtaydu, shundan so’ng uning bajarilishi davomiyligini yo’qotmasdan davom etadi, faqat uzilish yoki istisnoni qayta ishlash dasturni to’xtatishga majbur etadi.
Barcha uzilishlar va istisnolar 0 dan 255 gacha bo’lgan oraliqda nomerlangan (ko’pincha ular vektorlar deb ataladi). 0..31 nomerlar istisnolar uchun Intel firmasi tomonidan zaxiraga olingan.
