Receiving circuitry receives an access request that includes an input address. Lookup circuitry obtains a plurality of candidate sets that correspond with an index part of the input address. The lookup circuitry determines a selected storage location from the candidate sets using an access policy. The access policy causes the lookup circuitry to iterate through the candidate sets to attempt to locate an appropriate storage location. The appropriate storage location is accessed in response to the appropriate storage location being found.

Abstract: An apparatus and method are provided for arbitrating access to a set of resources that are to be accessed in response to requests received at an interface. Arbitration circuitry arbitrates amongst the requests received at the interface in order to select, in each arbitration cycle, at least one next request to be processed. Each request identifies an access operation to be performed in response to the request, the access operation being selected from a group of access operations. Further, each access operation in the group has an associated scheduling pattern identifying timing of access to the resources in the set when performing that access operation. In response to a given request being selected by the arbitration circuitry, access control circuitry controls access to the set of resources in accordance with the associated scheduling pattern for the access operation identified by that request.
