Abstract
Within a data processing system, data transfer between a host device and a slave device is accomplished with only one write operation. The write operation performed by the host device, such as a central processing unit, is performed to an alias destination address, which is related to the destination address by an offset number. The data included within the write operation includes the source address of the data to be transferred. Such a data transfer operation could be utilized to transfer data to a display adapter for display of video related data on a display device.
