![]() ![]() Open-source processors are increasingly being adopted by the industry, which requires all sorts of open-source implementations of peripherals and other system-on-chip modules. Presented in this paper are useful for hardware designers to optimize their cache designs or the This is in contrast to what was observed in previous studies for the shared L2 cache. (Least Recently Used) replacement policy outperforms all of the other replacement policies. Our experimental results show that for the private L1 caches, the LRU Publicly available SESC simulator, which models in detail a multicore processor with a multilevelĬache hierarchy. The number of cores is steadily increased from 1 to 16. We measure the miss rates of various cache replacement policies, as In this study, weįocus on the top level of the hierarchy, which bears the brunt of the memory requests emanatingįrom each processor core. Studies have focused on the shared levels of the multicore cache hierarchy. Multicore, there is a need to study cache replacement policies for multi-core systems. As most of the processor designs have become Cache replacement policy is an importantĭesign parameter of a cache hierarchy. With the number of transistors in a chip continuing to increase, the number ofĬores in a processor is also expected to increase. Multicore processors have become ubiquitous, both in general-purpose and special-purposeĪpplications. ![]()
