Abstract
An apparatus comprises two or more partition identifier registers, each corresponding to a respective operating state of processing circuitry and specifying a partition identifier for that operating state. The processing circuitry issues a memory transaction specifying a partition identifier depending on the partition identifier stored in a partition identifier register selected based on the current operating state. The memory system component selects one of a number of sets of memory system component parameters in dependence on the partition identifier specified by a memory transaction to be handled. The memory system component controls allocation of resources for handling the memory transaction or manages contention for the resources in dependence on the selected set of parameters, or updates performance monitoring data specified by the selected set of parameters in response to handling of said memory transaction.
