Message-passing communication system generating task for monitoring a specific communication path

摘要

A message-passing communication system including plural communication paths that can be simultaneously used for inter-process communication by which data is received without predetermining the address in order to avoid undesirable consumption of CPU resources is provided. The message passing communication system includes user memory areas having one or more communication tasks wherein each communication task monitors only one of the communication paths, interprets the communication protocol used for the monitored communication path, and converts the communication protocol into a predetermined communication protocol when data is sent via the monitored communication path. The user memory areas also include an arrival-data queuing unit for storing plural data in the order of arrival and a user task for extracting the data stored in the arrival-data queuing unit wherein, the user task interprets the predetermined communication protocol and executes a user application program using the extracted data.
