Abstract

A packet processor having a general-purpose arithmetic operator and another dedicated circuit, which extracts a particular field from the general-purpose register as object field, on which the predetermined general-purpose arithmetic operation is to be performed by the general-purpose arithmetic operator and writes a result of the arithmetic operation by the general-purpose arithmetic operator into the general-purpose register as updated information of the particular field. Based on the extraction and write process of the packet field designated by software (instructions), the packet processor realizes high flexibility and high speed processing.
