Eliminating Inter-proces Cache Interference Through Reconfigurability for Real-time and Low Power Embedded Systems

This study proposes a technique which leverages data cache reconfigurability to address the problem of cache interference in multitasking embedded systems. Modern embedded systems often implement complex applications, comprising of multiple execution tasks with heavy memory requirements. Data caches are necessary to provide the required memory bandwidth. However, caches introduce two important problems for embedded systems. Cache outcomes in multi-tasking environments are difficult to predict, thus resulting in very poor real-time performance guarantees. Additionally, caches contribute to a significant amount of power…
