Ingatan utama menggunakan keupayaan pemindahan blok, di mana masa capaian perkataan pertama (8 bit) adalah selama 60ns dan masa capaian adalah selama 4ns untuk setiap perkataan seterusnya. Cari masa capaian untuk ingatan para sekiranya para terlepas berlaku. (Andaikan ingatan para menunggu sehingga garis para telah diambil dari memori utama) Consider a 1-level cache memory with an access time of 1.5ns. The main memory uses a block transfer capability, where for first word (8 bit) access time is 60ns and the access time is 4ns for the each word thereafter. Find the access time when there is a cache miss. (Assume that the cache waits until the line has been fetched from the main memory) (3 markah/marks)
