PERIPHERAL INTERFACE WITH DELAYED FLOW CONTROL FOR RUN LENGTH ENCODED DATA TRANSFERS

摘要

A method implemented in a computer peripheral having an IEEE 1284 interface controller for managing the transfer of data to the interface controller includes detecting a condition requiring the computer peripheral to control the flow of transfer of data to the interface controller and if a run length encoded data transfer to the interface controller is pending, delaying the control of flow of the transfer of data until a RLE data byte associated with the end of the pending run length encoded data transfer is received by the interface controller.
