Title: Lru system considering access frequency
Inventor: YAMANE YASUO
IPC: G06F12/08
Filed: 1990-11-28
Abstract: PURPOSE:To improve a hit rate by setting up the rate of probability of purging a certain data from a buffer memory to probability of purging data whose access frequency is larger than that of the former data to a prescribed value. CONSTITUTION:The access frequency of all data stored in the buffer memory is stored and identified. When it is necessary to purge already stored data in order to input new data when the buffer memory is filled with existing data, a purge data determining means sets up the rate of the probability of purging a certain data to the probability of purging data whose access frequency is larger than that of the former data to a prescribed value, e.g. '1'.
