Also list if each reference is a hit or a miss, assuming the cache is initially empty.

Question
Caches are important to providing a high-performance memory hierarchy to processors.
Below is a sequence of ten memory references in binary to an empty eight- one word block
cache.
10110,11010,10110,11010, 10000, 00011, 10000, 10010, 10000, 10111
For each of these references tabulate the tag, valid bit status, the index, and the data given
a direct-mapped cache. Also list if each reference is a hit or a miss, assuming the cache is
initially empty.
