摘要: An enhanced interface between a processor and an Asynchronous Transfer Mode (ATM) segmentation controller. A software driver communicates with the controller to efficiently segment protocol data units (PDUs) into ATM cells for transmission. The creates series of structures in memory managing PDU, wherein include linked list buffer descriptors that describe size location subportions PDU. is capable accessing interpreting these structures. As result, only single I/O operation required initiate direct access (DMA) operations by retrieve from subsequently transmit
