A Study of Cache Management Mechanisms for Real-Time Embedded Systems

Due to the rapid development in the technology, embedded systems have an effective part in controlling and managing variety of hardware and software systems. These systems plan to solve problems that make embedded systems become more complex than before. The majority of embedded systems are currently intended to be more interactive with the environment and process data in real-time in order to fulfil requirements that recruited for. Thus, this requires a high speed of processing data to produce an output. Hence multicore processors are usually employed in embedded system design. To ensure that embedded systems as processing units work perfectly to finish a task with expecting the Worst-Case Execution Time (WCET). A considerable number of researches have been done to handle cache memory organization for multicore processor units in real-time embedded systems. To this end, this paper presents a study of cache management techniques in real-time embedded systems.
