Data packet transmission system and method

A method for transmitting data from a processor to a destination device, comprising the steps of:

• storing in a memory block of the processor a buffer descriptor array having a plurality of elements, each element indicating a selected one of the data packet segments:
• receiving at a communication controller of the processor a signal indicating a location of the buffer descriptor array;
• transmitting from the communication controller to the destination device the data packet segments indicated by the buffer descriptor array elements:
• storing a header in the memory block of the processor;
• and
• transmitting from the communication controller to the destination device the header;
• and
• wherein the step of storing the buffer descriptor array comprises the step of storing in the buffer descriptor array a second plurality of elements, each indicating the header.

A method for transmitting data from a processor to a destination device, comprising the steps of:

• storing a data packet in a memory block of the processor;
• storing a header in the memory block of the processor;
• storing in the memory block of the processor a buffer descriptor array having a first plurality of elements and a second plurality of elements alternating with the first plurality of elements, each one of the first plurality of elements indicating the header, and each one of the second plurality of elements indicating a corresponding segment of the data packet;
• transmitting to a communication controller of the processor a pointer having an address of the buffer descriptor array;
• and
• transmitting by the communication controller to the destination device, in response to the pointer, the header and the segments of the data packet.
