Abstract
A digital data transfer system comprises a source module and a destination module interconnected by an information transfer medium. The source module initiates a transfer operation in which it transfers a data item and an associated address over an information transfer medium. The address having an aperture identification portion that identifies one of a plurality of apertures. The destination module receives the data item and the associated address from the information transfer medium during the transfer operation, the destination module using the one of the plurality of apertures identified by the aperture identification portion to generate an aperture value for association with the data item. The source module can also initiate a retrieval operation, during which it transfers an address over the information transfer medium to retrieve previously transferred information. The address used during the retrieval operation also has an aperture identification portion that includes an aperture identification value that identifies one of a plurality of the apertures. The destination module provides a response value in response to the address provided by the source module during the retrieval operation. In one embodiment, the destination module transfers one of the previously-transferred data item or the generated aperture value, depending on the aperture identification portion of the address. In another embodiment, the destination module transfers the data item and a correspondence indication indicating whether the aperture value corresponds to the aperture identification value provided in the address.
