Struktur mesin dilengkapi dengan memori utama $8$MB dengan ukuran blok $128$ bit masing$-$

masing, dan cache yang mempunyai $2K$ barisan. Dengan menggunakan teknik pemetaan

bersekutu set $2-$arah $($rujuk Rajah $2),$ jawab soalan berikut.

A machine structure is equipped with a $8MB$ main memory with a block size of $128$ bits each,

and a cache that consist of $2K$ lines. Using a $2-$way set associative mapping technique $($refer

to Figure $2),$ answer the following questions.

Address length $=(s+w)$ bits

Number of addressable units $=2^{s+w}$ words or bytes

Block size $=$ line size $=2^v$ words or bytes

Number of blocks in main memory $=\frac{2^{s+v}}{2^w}=2^s$

Number of lines in cache $=m=2^x$

Size of cache $=2^{x+u}$ words or bytes

Size of tag $=(s-r)$ bits

Number of lines in set $=k$

Number of sets $=v=2^d$
