1. A method for prefetching data, the method comprising:
loading first data from a first memory location;
caching the first data in a cache memory; and
limiting overfetching of data by prefetching other data to the cache memory based on a comparison of a threshold compression ratio indicating a minimum acceptable compression level for performing prefetching with an average of a compression ratio of the first data and of a compression ratio of the other data.
