Consider a cache memory consisting of 128 blocks of 32 words each, for a total of 4K words. Assume that Main memory is addressable by a 32 bit address. The MM has 4 Giga words, which we will view as 1 Mega Blocks of 4K words each. For simplicity we will assume that consecutive addresses refer to consecutive words.
What is the Main Memory address format if Direct mapping is used
please format as Tag|Block|Word
