Dear Hong Chiat,

Please see my comments below.

Good day professor

I have some question regarding

Lecture Material for Week #9

ComputerMemory-Week9 slide 27.

1) Let say the cache is not filled by any memory block currently.

So when memory block 33 map to a cache block 3 for example. The cache access will be successful  as it is empty.

So based on the definition of hit which is “A hit is when data is found at a given memory level”,

should this be considered as cache hit or miss?

[Jason] If the cache is initially empty, there is no data in the cache. Data will need to be fetch from the main memory. So, an empty cache will result in cache miss.
