a cache may be organized such that: in one case, there are more data elements per block and fewer blocks in another case, there are fewer elements per block but more blocks however, in both cases - 1.0., larger blocks but fewer of them or shorter blocks, but more of them - the cache's total capacity (amount of data storage) remains the same what are the pros and cons of each organization? support your answer with a short example assuming that the cache is direct mapped (ii) assume: a processor has a direct mapped cache data words are 8 bits long (i.e., 1 byte) data addresses are to the word a physical address is 20 bits long the tag is 11 bits each block holds 16 bytes of data how many blocks are in this cache? (in) consider a 16-way set-associative cache: - data words are 64 bits long - words are addressed to the half-word - the cache holds 2 mbytes of data - each block holds 16 data words - physical addresses are 64 bits long how many bits of tag, index, and offset are needed to support references to this cache?
