1. An integrated circuit comprising:

  • execute circuitry operable to execute at least part of an encryption process involving a set of data having numerousness N, the circuitry arranged to update at least first and second data concurrently in the set in a series of overlapping iterations followed by subsequent overlapping iterations in the series wherein at least one of the second data depends on the uncompleted processing of the first data; and

    an assemblage of memory elements coupled to the execute circuitry having at least two read ports and at least two write ports operable for concurrent read and write, the elements having addresses, the number of memory elements being bounded in numerousness by the number N and sufficient to be utilized by the execute circuitry for updating the set of data for a subsequent iteration in the series.
