Data rearrangement processor.

摘要

To rearrange the arrangement order of a byte data read from an external memory into a data arrangement order suitable for a microprocessor or the arrangement order of a byte data read from an internal memory into a data arrangement order suitable for an external memory, the byte data is rotated by a rightward byte rotator (21) or a leftward byte rotator (23) provided between an internal bus and an external bus without depending upon software, thus increasing data arrangement speed and decreasing data access time and program storing capacity.
