DATA COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a data communication system for reducing a load on a processor by reducing the number of times of the generation of an interrupt signal indicating that communication data transmitted by packet units through a network are received. SOLUTION: In this data communication system, a status flag indicating that following communication data are present and that the communication data can be continuously transferred is erected in a descriptor added to each head of continuously received communication data so that the continuous communication data can be integrally handled and that the incoming of a series of communication data can be indicated to a CPU by one interrupt signal.
