Abstract: Apparatuses and methods for prefetch generation are disclosed. Prefetching circuitry receives addresses specified by load instructions and can cause retrieval of a data value from an address before that address is received. Stride determination circuitry determines stride values as a difference between a current address and a previously received address. Plural stride values corresponding to a sequence of received addresses are determined. Multiple stride storage circuitry stores the plurality of stride values determined by the stride determination circuitry. New address comparison circuitry determines whether a current address corresponds to a matching stride value based on the plurality of stride values stored in the multiple stride storage circuitry. Prefetch initiation circuitry can causes a data value to be retrieved from a further address, wherein the further address is the current address modified by the matching stride value of the plurality of stride values.

Abstract: Storage circuitry is provided, that is designed to form part of a memory hierarchy. The storage circuitry comprises receiver circuitry for receiving a request to obtain data from the memory hierarchy. Transfer circuitry causes the data to be stored at a selected destination in response to the request, wherein the selected destination is selected in dependence on at least one selection condition. Tracker circuitry tracks the request while the request is unresolved. If at least one selection condition is met then the destination is the storage circuitry and otherwise the destination is other storage circuitry in the memory hierarchy.

Abstract: An apparatus and method are provided for efficient utilisation of an address translation cache. The apparatus has an address translation cache with a plurality of entries, where each entry stores address translation data used when converting a virtual address into a corresponding physical address of a memory system. Each entry identifies whether the address translation data stored therein is coalesced or non-coalesced address translation data, and also identifies a page size for a page within the memory system that is associated with that address translation data. Control circuitry is responsive to a virtual address, to perform a lookup operation within the address translation cache to produce, for each page size supported by the address translation cache, a hit indication to indicate whether a hit has been detected for an entry storing address translation data of the associated page size.
