Comparing Separate and Statically-Partitioned Caches for Time-Predictable Multicore Processors

In this paper, we quantitatively compare two different time-predictable multicore cache architectures, separate and statically-partitioned caches, through extensive simulation. Current research trends primarily focus on partitioned-cache architectures in order to achieve time predictability for hard real-time multicore based systems, and our experiments reveal that separate caches actually lead to much better performance and energy efficiency when compared to staticallypartitioned caches, and both of them are adequate for timing analysis for real-time multicore applications.
