Controllers in memory information search when does it work

Controllers in memory information search when does it work

  • posle fiksatsii promaxa ( skvoznoy prosmotr ).
  • Cache- in memory block search with a at the time , in the cache when encountered , fast to memory appeal is stopped ( delayed see ).

Kontroller xotiradagi ma’lumotlarni qidirishni qachon bajaradi?

Kontroller xotiradagi ma’lumotlarni qidirishni qachon bajaradi?

  • после фиксации промаха (сквозной просмотр).
  • Kesh-xotiradagi blokni qidirish bilan bir vaqtda, keshda uchraganda, tezkor xotiraga murojaat to’xtatiladi (kechiktirilgan ko’rish).

Cache memory formed of basic issues

  • Cache memory basic memory addresses description algorithms .
  • Cache - from memory basic to memory information and instructions write algorithms .
  • Cache- in memory lines exchange algorithms .
  • Cache memory size _
  • Cache- in memory lines length _

Kesh-xotirani tashkil etishning asosiy masalalari

  • Kesh-xotirasiga asosiy xotira adreslarini tasvirlash algoritmi.
  • Kesh-xotiradan asosiy xotiraga ma’lumotlar va ko’rsatmalarni yozish algoritmi.
  • Kesh-xotiradagi satrlarni almashtirish algoritmi.
  • Kesh-xotira o’lchami.
  • Kesh-xotiradagi satrlar uzunligi.

Description algorithms

  • Direct mapping.
  • Associative (full associative mapping).
  • Set -associative mapping.

Tasvirlash algoritmlari

  • To’g’ridan-to’g’ri (direct mapping).
  • Assotsiativ (full associative mapping).
  • Assotsiativ-to’plami (set-associative mapping).

Address description algorithms comparison

  • Straight away
  • ( Full ) associativity
  • Plural-associative
    • 1 block - one how many satr
    • Compromise variant
