Data packet processing method

A data packet processing method adapted to be applied in a processor performing data processing operations, the method comprising the following steps of:

• receiving data packets, each of the data packets including a first key message that indicates at least source of the data packet and a second key message;
• executing a first analyze for analyzing the first key messages of the data packets;
• determining whether the data packet is a high priority source data packet or a normal source data packet according to the result of analyzing the source of the data packet;
• executing an Rx high priority interrupt in response to determining that the data packet is the high priority source data packet;
• executing a second analyze for analyzing the second key message of the data packet in response to determining that the data packet is the normal source data packet;
• determining whether the normal source data packet is the high priority data packet or a normal data packet according to a result of analyzing the second key message of the normal source data packet;
• and
• executing the Rx high priority interrupt in response to determining that the normal source data packet is the high priority data packet;
• wherein the Rx high priority interrupt is to immediately transmit an interrupt signal to interrupt receiving of the data packets such that currently-received data packets can be instantaneously processed, and
• wherein the first analyze is different from the second analyze.
