摘要： A packet-data-processing apparatus includes a first data-processing unit for computing information on a processing count; a memory; a second data-processing-unit for processing the input packet and storing first results in the memory; an access mechanism unit for reading out one of the first results written into the memory least recently from the memory at a request for a read operation and deleting the result of processing read out from the memory; a third data-processing unit for making the request for a read operation and carrying out processing based on the first result read out by the access control unit at the request and an input packet associated with the result of processing; and fourth data-processing unit constituting pipeline data-processing mechanism with the first and third data-processing unit.
