ABSTRACT:
A high bandwidth gateway comprises a source of packet traffic wherein received packets are stored in a buffer, a destination interface circuit for the packets, a microprocessor and a bus that interconnects the components. The microprocessor, which in the prior art controls data transfers, periodically gives up control to a hardware assist engine. The hardware assist engine detects the presence of packets in the source buffer and causes the source buffer to output one or more packets to the destination directly, thus by-passing the microprocessor completely. By this system, bandwidth is improved by the source and the destination working together directly, without having the overhead associated with microprocessor-based or initiated data transfers.
