Abstract
A method for storing a sequence consisting of a repeated data pattern of three bytes to a memory in double word increments aligned with double word boundaries. A register is loaded with the first four bytes of the sequence. The contents of the register are then repeatedly stored to consecutive locations of the memory. Between each storing of the register's contents, the contents are updated to the next four bytes of the sequence by shifting the second through fourth bytes to the first through third bytes and also moving the second byte to the fourth byte. When the beginning address where the sequence is to be stored in memory is not aligned with a double word boundary, the initial bytes of the sequence up to the double word boundary are stored and the contents of the register updated to the next four bytes of the sequence.
