A packet processing accelerator comprises a programmable packet classification module, a programmable flow control module, and a programmable packet header modification module. The programmable packet classification module is configured to receive a data packet and generate a start location of each protocol header of the data packet and a first index. The first index indicates classification of the data packet. The programmable flow control module is configured to generate a code of an output port and an action code according to the start location of each protocol header of the data packet and the first index. The programmable packet header modification module is configured to modify content of a plurality of protocol headers of the data packet according to the action code and to send the modified data packet to an output port according to the code of the output port.
