Abstract: A circuit is provided for transferring a multibyte word of data from a buffer memory to a main memory beginning at any available byte position in the main memory. A gating circuit is controlled in response to an address designating the starting byte position for skewing bytes from the buffer to the starting byte position and to any remaining byte positions of the first addressed word location of the memory. A set of registers and a gating circuit are provided for storing any remaining data bytes from the word read from the buffer. On subsequent transfers, data is transferred simultaneously from the buffer and the register to form a complete word for storage in the main memory and remaining bytes from the buffer are then entered into the register for a subsequent transfer.
