Mar 2, 2018 · The L1 cache needs to run synchronous to the CPU in order to be useful, so the size of the cache is a limiting factor in clock speed. Other cache layers can be larger and run at slower …

In this case that is 2^ (4+4) * 4 = 256*4 = 1 kilobyte. For the same size cache (capacity), if you were to go from 4-way to two-way set associative, it two way associative, you could do so by either doubling …

3 Categorizing Cache Misses I was wondering if somebody could provide an example illustrating a capacity miss in contrast to a conflict miss for a 2-way cache with arbitrarily small line size and cache …

Oct 20, 2014 · A cache with a line size of L 32-bit words, S number of sets, W ways, and addresses are made up of A bits. Assume that the cache is word addressed, i.e., the low two bits of the address are …

Is there is a correspondence between cache sizes and access latency? All other things being equal, does a larger cache operate slower? If so, why? How much slower?

Nov 26, 2015 · Your cache has 4 blocks of 4 bytes per block each ==> cache size is 16 bytes. Each cache block (4 bytes) stores one word (4 bytes). Thus, there are no byte select bits. (In this machine …

Sep 17, 2017 · On cache-line splits, it's still only a single uop, but does multiple cache accesses. The penalty is still small, except on 4k-splits. Skylake makes even 4k splits fairly cheap, with latency …

Note that if the set size were 256 bits, it would make the cache fully associative rather than direct mapped: a situation in which the entire cache is one big set of blocks, and so there is no set field in …

In write through cache, both main memory and cache are simultaneously updated and in write back cache only modified cache word is copied to main memory when that word is to be replaced with …

Apr 3, 2013 · Suppose you have a 64-byte cache on a system with 16-bit memory addresses. If the cache is direct-mapped and it has 10 bytes of tag overhead in total, how many bits are used for the …
