1번 문제 풀이

average rotational latency 즉 회전 지연 시간을 구하는 문제이다.

0.5rotation/(7,200/60RPS) = 4.167 (아마 근삿값으로 오차도 허용)

transfer time 데이터에 접근해서 데이터를 전송하는데 걸리는 시간 거/속*시, 즉 transfer rate 속도가 34MB/sec 로 주어졌고 거리는 1024byte = 1KB로 주어져있으니까 시간은 거/속 1KB/(34MB/sec) = 0.029ms(오차범위허용) 1/34 해준 값임

controller overhead : 문제에서 주어진 480 Mbits/sec을 물리단위 변환하라는 문제 1byte는 8bit니까 (480*M/8)/sec 계산하면 

60MB/sec 를 ms로 변환하면 1/60 하라는 거 그래서 0.017ms

4개 (average rotational latency + transfer time + controller overhead + average seek time) 다 더하면

4.167 + 0.029 + 0.017 + 11 = 15.206

1번 문제 풀이

block 개수 = (32K/2)/8 = 2K = 2의 11승 

index size = 11

tag size = 64-(11+1+3) = 49

valid + tag = metadata

total cache size = #blocks * (valid + tag + data) = 2의11 * (1 + 49 + 2*64)

block 개수 = (64K/16)/8 = 0.5K = 2의 9승

index size = 9

tag size = 64-(9+4+3) = 48

total cache size = 2의9 * (1 + 48 + 16*64) = 549376 (콤마 쓰지 말것)
