Abstract

The disclosure is directed to a cache management system ('system') for storing data in a cache of a computer system in a compact form. The system identifies multiple instances of a candidate value stored in a primary cache and stores those instances as a single value in a value cache. The system stores multiple pointers to the candidate value in the value cache, e.g., as many as the number of occurrences of the candidate value in the primary cache, each of which corresponds to an address in a memory of the computer system storing an instance of the primary cache candidate value. By storing multiple instances of the candidate value as a single instance, the system reduces the cache pollution and the memory bandwidth and facilitates storing more number of distinct values in the primary cache of a given size.
