Abstract

Data processing apparatus includes a storage circuit or memory, and an addressing circuit for identifying word locations within the storage circuit or memory into and from which a plurality of information items are to be written and read, respectively. A translating circuit is provided for successively shifting, in a write mode of operation, at least a portion of each information item so that it is stored in the storage circuit in a manner that the stored information item in each word location has a bit order different from that order of any other information item as stored in the storage circuit. In a read mode of operation, the translating or de-skewing circuit shifts the information items as read out from the storage circuit in a direction opposite to that imparted during the writing mode.
