Management of the last level cache for multimedia application system

To achieve high efficiency and ensure Quality of Service (QoS), the last-level cache of Chip Multiprocessors has to be carefully managed. Previously proposed cache management schemes focus on reduction of the overall number of misses and or by allocating cache capacity without taking into consideration the applications' memory sharing characteristics. In this work we describe an adaptive scheme for last-level caches that balance the high efficiency and QoS for multimedia application system. The proposed scheme improves both system throughput and execution fairness. Our detailed, full-system simulations showed an average improvement for a multimedia system. ? 2014 IEEE.EI
