Abstract: Data processing circuitry comprises a processing element to execute successive iterations of program code to access a set of data elements in memory, each iteration accessing one or more respective data elements of the set; a data element structure memory to store a memory address relationship between the data elements of the set; and prefetch circuitry, responsive to an access by a current program code iteration to a current data element of the set, to detect, using the memory address relationship stored in the data element structure memory a memory address defining a subsequent data element to be accessed by a next program iteration and to initiate prefetching of at least a portion of the subsequent data element from memory.
