Abstract
Cache lines of a data cache may be assigned to a specific page type or color. In addition, the computing system may monitor when a cache line assigned to the specific page color is allocated in the cache. As each cache line assigned to a particular page color is allocated, the computing system may compare a respective index associated with each of the cache lines to determine maximum and minimum indices for that page color. These indices define a block of the cache that stores the data assigned to the page color. Thus, when the data of a page color is evicted from the cache, instead of searching the entire cache to locate the cache lines, the computing system uses the maximum and minimum indices as upper and lower bounds to reduce the portion of the cache that is searched.
