Abstract
An apparatus comprises processing circuitry to process data access operations specifying a virtual address of data to be loaded from or stored to a data store, and proxy identifier determining circuitry to determine a proxy identifier for a data access operation to be processed by the data access circuitry, the proxy identifier having fewer bits than a physical address corresponding to the virtual address specified by the data access operation. The processing circuitry comprises at least one buffer to buffer information (including the proxy identifier) associated with one or more pending data access operations awaiting processing. Address translation circuitry determines the physical address corresponding to the virtual address specified for a data access operation after that data access operation has progressed beyond said at least one buffer.
