ABSTRACT:
In a high speed data processing system, there is provided a circuit for shifting either right or left as data is transmitted to or from the main storage unit. Apparatus for high speed parallel byte shifting is connected to the data bus which connects the main storage unit to the system and comprises logic which selects predetermined byte lines. Information from the individually selected byte lines is temporarily stored in parallel buffer registers and subsequently returned to a different byte line to provide byte shifting without the requirement of shift registers or complex logic.
