Consider the cache memory depicted in Figure . For a main memory capacity of 2* words, determine the total number of bits in the cache array and derive the contribution of nondate bits as a percentage overhead relative to actual data bits. 

Repeat above part for the cache memory depicted in Figure.

 Direct-mapped cache holding 32 words within eight 4-word lines. Each line is associated with a tag and a valid bit

  Two-way set-associative cache holding 32 words of data within 4-word lines and 2-line sets.
