摘要： In a distributed control system in which a plurality of nodes are connected to a transmission line, each node controlling components connected to this node and transmitting a message to other nodes, a message sent by each node includes at least two message-sending condition-identifying portions, one of the condition-identifying portions including data indicating a message-receiving node or non-designation of a message-receiving node; and a comparison-selection circuit provided in each node includes registration parts for registering data of message-receiving conditions, at least two registration parts for comparing contents of the condition-identifying portion in the taken-in message with the data of message-receiving conditions registered in the registration parts, a received-message storing part for storing a message to be received in this node, a control part for determining whether or not the taken-in message is to be received in this node based on a result of comparison-processing performed in the comparison and selection means and for transferring the taken-in message to the received-message storing part if it is determined that the taken-in message is received in this node, otherwise, abandoning the taken-in message.

摘要： A micro-controller includes a dictionary memory for storing instruction codes which appear in a program, and a compressed code memory for storing compressed codes each converted from each of the instruction codes included in the program. Each compressed code has a word length sufficiently long to identify all instruction codes included in the program. Each compressed code has a value indicative of an address in the dictionary memory at which an associated instruction code is stored. The micro-controller is responsive to an instruction code read request which specifies an address of a compressed code to read the compressed code stored in the specified address in the compressed code memory, and to subsequently read an instruction code stored in an address indicated by the compressed code in the dictionary memory.

摘要： In a distributed control system with a plurality of nodes connected to a transmission line, each node controlling components and transmitting a message to other nodes, a message includes at least two message-sending condition-identifying portions, one of the portions including data indicating a message-receiving node or non-designation of a message-receiving node. A comparison-selection circuit in each node includes at least two registration parts for comparing contents of the condition-identifying portion in the taken-in message with the data of message-receiving conditions registered in the registration parts, a received-message storing part for storing a message to be received, a control part for determining whether or not the taken-in message is to be received based on a result of comparison-processing performed in the comparison and a selector transferring the taken-in message to the received-message storing part if it is determined that the taken-in message is to be received, otherwise, abandoning the taken-in message.
