WebSep 20, 2024 · A processor cache is denoted by the tuple (C, k, L) where C is the capacity, k the associativity and L the line size. Based on the various values of k, three types of caches are known. These are direct mapped cache with k = 1, set associative cache with k > 1, fully associative cache with one set and n blocks. Webcache.19 A Two-way Set Associative Cache ° N-way set associative: N entries for each Cache Index • N direct mapped caches operates in parallel ° Example: Two-way set …

WebMay 7, 2024 · Therefore, you can simply cache the response in memory and serve it very fast. Once there is new data, write it to the database, invalidate the cache, and update it asynchronously. Caching is also useful for user meta information. When you’ve logged in to any site, the user data will be required on every page.
