ABSTRACT:
A rate based mechanism for determining which data to replace in a cache when the cache is full. The computer system processes data, which are associated with multiple channels or processes. These channels or processes have different, cyclic rates. When the cache is full, the system chooses the data to replace by selecting the data block in the cache that has the lowest rate and is the most recently used.
