Of memory hierarchical structure

Basic memory . Static and dimanic memory structure

Xotiraning iyerarxik strukturasi
Asosiy xotira. Statik va dimanik xotira tuzilishi
Large size information save the problem hal to do traditional way , memory hierarchical apparently formed reach with instead is increased (Figure 1).
Figure 1 Memory five sathli apparently formed reach _
Katta hajmdagi ma’lumotlarni saqlash muammosini hal qilishning ananaviy yo‘li, xotirani ierarxik ko‘rinishda tashkil etish bilan amalga oshiriladi (1-rasm).
1-rasm. Xotirani besh sathli ko‘rinishda tashkil etish.
Of the processor internal registers hierarchy eng high section located . To them appeal to do speed , other kind of memories relatively much is high ( a how much nanoseconds , 1ns = 10 -9 ).
Next in a row current at the time size 32 Kbytes a how much megabytes to be possible cache memory _ located .
Protsessorning ichki registrlari ierarxiyaning eng yuqori qismida joylashgan. Ularga murojaat qilish tezligi, boshqa xil xotiralarga nisbatan ancha yuqoridir (bir necha nanosekund, 1ns=10-9).
Keyingi qatorda hozirgi paytda xajmi 32 Kbaytdan bir necha megabaytgacha bo‘lishi mumkin bo‘lgan kesh-xotira joylashgan.
Of the hierarchy third step , size a how much on gigabytes has to be possible which was basic memory ( random access memory , OZU ) located . The speed at which it is applied is a few nanoseconds .
Next in rows magnetic disks and tapes , and optics disks based on using running memory devices located .
Ierarxiyaning uchinchi pog‘onasida, hajmi bir necha o‘n gigabaytlarga ega bo‘lishi mumkin bo‘lgan asosiy xotira (tezkor xotira, ОЗУ) joylashgan. Unga murojaat qilish tezligi – bir necha o’z nanosekund.
Keyingi qatorlarda magnitli disklar va lentalar, hamda optik disklar asosida yordamida ishlaydigan xotira qurilmalari joylashgan.
Hierarchy across from above down depending on , three pointer changing to go we can see possible .
First - to memory appeal to do time growing up goes _ In the registers this time - one how much nanoseconds , cache- in memory henceforth salgina more , basic in memory esa a how much on nanoseconds formed does . Next in rows differences even larger - to discs appeal to do time at least 10 mks larvae , optics disks and magnet on tapes esa even bigger _ values has will be , and in seconds measured .
