- Fill to memory one in a transaction do possible Kesh-xotira liniyalari hamji qanday bo’lishi kerak? - Liniya o’lchami kamida xotira kanalining kengligida bo’lishi kerak
- Katta o’lcham
- Keshning «assotsiativligi»va liniyalar sonini kamaytirishga imkon beradi - Katta o’lcham
- Ixtiyoriy murojaat uchun xotira kanalidan yanada samarali foydalanish - To’ldirishni xotiraga bitta tranzaksiyada bajarish mumkin Cache basic parameters how to be do you need - Cache size
- Cache association degree
- Large , mine avoids probes
- Small , fast appeal to do for
- Cache lines size
- Large , from localization use for
- Large , tags reduce for
- Small ( if data in memory optional distributed if in the cache useful data share large )
Keshning asosiy parametrlari qanday bo’lishi kerak? - Kesh o’lchami
- Kesh assotsiyativlik darajasi
- Katta, чтобы избегать пробуксовки
- Kichik, tez murojaat qilish uchun
- Kesh satrlar o’lchami
- Katta, lokallashtirishdan foydalanish uchun
- Katta, teglarni kamaytirish uchun
- Kichik (agar ma’lumotlar xotirada ixtiyoriy taqsimlangan bo’lsa, keshdagi foydali ma’lumotlarning ulushi katta)
