Abstract
A method for the simultaneous bidirectional transfer of digital data at a ry high rate between a host digital data processor and an external device includes the steps of: loading the output data into a data register of the processor; loading an address reference of an external device into an address register of the processor; forming a composite address consisting of the sum of the data register and an address register; and exporting the output data through the address lines from the processor to the external device while simultaneously reading data into the processor from the external device. The method accomplishes rapid data transfer by advantageously transferring data over what would normally be address lines between the processor and the external device. This method is suitable for applications where data is to be transferred from a processor operably coupled to only one external device.
