Since the advent of multi-core processors, different multi-core system and in particular processor architectures have emerged exhibiting individual advantages and disadvantages. One of the main distinguishing factors among these architectures is their varying degree and type of resource sharing among individual cores. On the one hand, resource sharing is necessary for the cores to communicate, while on the other hand resource sharing is often used for economic reasons. Depending on the degree and type of resource sharing, the impact on performance depends on the workload applied and can vary to a large extend.
