Abstract
A method and system for transferring data bytes includes a first memory adapted to store a plurality of multiple-byte data words including header field bytes and one or more data field bytes. The system also includes a second memory adapted to store data field bytes transferred thereto from the first memory. A controller coupled to the first and second memories reads a data word including the header field byte and the one or more data field bytes out of the first memory. The system also includes a data packer coupled to the controller and the second memory. The controller and data packer cooperate to transfer the one or more data field bytes of the first data word read from the first memory to the second memory. The data packer stores only the one or more data field bytes in the second memory contiguously with a previously transferred and stored data field byte.
