A CPU cache is a hardware cache used by the central processing unit (CPU) of a computer to reduce the average cost (time or energy) to access data from the main memory. [1] A cache is a smaller, faster memory, located closer to a processor core, which stores copies of the data from frequently used main memory locations.

L2 cache is important for the Lion Cove core architecture as Intel's reliance on L2 cache is to insulate the cores from the L3 cache's slow performance. [8] Lion Cove was designed to accommodate L2 caches configurable from 2.5 MB up to 3 MB depending on the product.

A browser's cache stores temporary website files which allows the site to load faster in future sessions. This data will be recreated every time you visit the webpage, though at times it can become corrupted. Clearing the cache deletes these files and fixes problems like outdated pages, websites freezing, and pages not loading or being ...
The resulting load on memory use is known as pressure (respectively register pressure, cache pressure, and (main) memory pressure). Terms for data being missing from a higher level and needing to be fetched from a lower level are, respectively: register spilling (due to register pressure : register to cache), cache miss (cache to main memory ...
There are three levels of cache. The first consisted of separate 2 KB instruction and data caches. These are direct-mapped. The L2 cache is on-die and is 32 KB in size. It is eight-way set set-associative. The L3 cache is larger, supporting capacities of 512 KB to 2 MB, and is located externally.
