cache memory capacity and words in cache memory
No, it says each BLOCK has 4 words, and each word has 16 bits. Thus a block has 64 bits. Then it says, a SECTION has 2 blocks i.e 8 words, or 128 bits. The whole cache is 4’096 words, which would be 512 sections or equivalently 1’024 blocks, or 65’536 bits.
