Abstract
An ethernet card connected between a host computer and an ethernet includes a transmitting circuit connected between a CPU and a transceiver, a detection circuit connected between the CPU and a MAC (media access control), and an arbitration circuit to arbitrate packet data transmission order between packet data from the CPU to the ethernet and packet data from the host computer to the ethernet, wherein when the ethernet card receives packet data from the ethernet, packet data is received by the MAC through the transceiver and, at the same time the detection circuit is driven by the CPU to detect packet data received by the MAC. As a result the CPU directly drives the MAC to discard received packet data if packet data received by the MAC has nothing to do with the host computer, and the CPU immediately dispatches corresponding packet data to the ethernet through the transmitting circuit and the transceiver if packet data received by the MAC can be directly replied to by the ethernet card.
