Publication number: 20240152467Abstract: For a given application, increasing the size of a cache is beneficial up to a certain point and the number of hits does not increase significantly with a greater cache size. This disclosure provides a method to determine a miss ratio curve, for a cache having data blocks with a time-to-live. A hashed value of a data block's key address can be used to generate a 2D HLL counter for storing expiry times of the data blocks. The 2D HLL counter can be converted to a 1D array, from which a stack distance can be calculated. A frequency distribution of stack distances can then be converted into a miss ratio curve, from which an appropriate cache size can be selected.Type: ApplicationFiled: November 7, 2022Publication date: May 9, 2024Applicants: HUAWEI TECHNOLOGIES CANADA CO., LTD., The Governing Council of the University of TorontoInventors: Sari SULTAN, Kia SHAKIBA, Albert LEE, Michael STUMM, Ming CHEN, Chung-Man Abelard CHOW
