Automotive embedded systems have an increasing need for computing power. To address this issue, we can implement critical and non-critical tasks in the same multicore processor. A disadvantage of this kind of processor is the indeterminism it involves due to its complexity. New technologies, like dynamic allocation of cache memory, allow reducing the impact of this indeterminism. In this article, we provide an experimental approach to verify if the dynamic allocation of the cache memory of Intel (CAT Intel) is efficient.
