Abstract
In a data processing system, mapping circuitry is provided to map one of J first identifiers received from an upstream component to one of K second identifiers to be provided to a downstream component (K<J). K mapping entries are each associated with a respective second identifier and each store mapping information for identifying which first identifier is mapped to the associated second identifier. For a first subset of mapping entries, allocation circuitry prevents allocation of a given first identifier to a mapping entry of the first subset other than a selected group of one or more mapping entries of the first subset selected based on the given first identifier. For a second subset of mapping entries associated with a second subset of the K second identifiers, the allocation circuitry permits the given first identifier to be allocated to any mapping entry in the second subset.
