Abstract
A method for replacing cached data is disclosed. The method in one aspect associates an importance value to each block of data in the cache. When a new entry needs to be stored in the cache, a cache block for replacing is selected based on the importance values associated with cache blocks. In another aspect, the importance values are set according to the hardware and/or software's knowledge of the memory access patterns. The method in one aspect may also include varying the importance value over time over different processing requirements.
