    • 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.
    • 分组数据处理装置包括用于计算关于处理计数的信息的第一数据处理单元; 记忆 第二数据处理单元,用于处理输入分组并将第一结果存储在存储器中; 访问机构单元,用于在请求读取操作时从存储器中最少读出写入存储器的第一结果中的一个,并从存储器中删除从该存储器读出的处理结果; 第三数据处理单元,用于基于由访问控制单元根据请求读出的第一结果和与处理结果相关联的输入分组进行读操作请求和执行处理; 以及与第一和第三数据处理单元构成流水线数据处理机构的第四数据处理单元。
