Data communication for controlling message transmission and reception among processing modules using information stored in descriptor to form a loosely coupled multiprocessing system
 A message control system for a data communication system in the form of a loosely coupled multiprocessing system, in which a plurality of processing modules having a memory unit are coupled to each other via a system bus. In this message control system, a memory unit, within each processing module, includes a data processing part which is in software running on a central processing unit within its own processing module, a descriptor which manages address and data length information of a storage region for a message in the form of a chain, and a buffer which decomposes and stores a transmitting message. A connection unit within each processing module includes logical transmitting ports and a logical receiving port.
