METHOD OF OPTIMIZATION OF CACHE MEMORY MANAGEMENT AND CORRESPONDING APPARATUS

In order to optimize cache memory management, the invention proposes a method and corresponding apparatus that comprises application of different cache memory management policies according to data origin and possibly to data type and the use of increasing levels of exclusion from adding to cache of data the exclusion levels being increasingly restrictive with regard to adding data to cache as the cache memory fill level increases. The method and device allows among others to keep important information in cache memory and reduce time spent in swapping information in- and out of cache memory.
