WebFor a byte-addressable machine with 16-bit addresses with a cache with the following characteristics: It is direct-mapped Each block holds one byte The cache index is the four least significant bits Two questions: How many blocks does the cache hold? How many bits of storage are required to build the cache (e.g., for the Webtrade-off on cache design. We present the zcache, a cache design that allows much higher associativity than the number of physical ways (e.g. a 64-associative cache with 4 ways). The zcache draws on previous research on skew-associative caches and cuckoo hashing. Hits, the common case, require a single
