Abstract:
1. A processing system having a plurality of processing modules connected via a communication line, where each processing module comprises: a database to fetch either: a unique logical address indicating the processing module or a physical address of the processing module in the communication line, which are corresponding to mounting position information for each processing module in the communication line; a position identification device to identify the mounting position information which is defined according to the physical mounting position of the processing module in the communication line of the processing module; a unique/physical address conversion device to fetch the physical address corresponding to the unique logical address from the database; a communication device for performing communication between the processing modules; a memory for storing communication data received from the communication line according to a request from the communication device; a position/physical address conversion device to fetch the physical address corresponding to the mounting position information from the database; and an interrupt notification device to notify the processing module after receiving the communication data from another processing module and to notify the mounting position information of a source processing module; wherein, when a communication data packet is transmitted, the physical address is fetched from the unique logical address included in the communication data packet by the unique/physical address conversion device, and the communication data packet is transmitted to the physical address through the communication line; and when a communication data packet is received, a source mounting position information of the communication data packet which is notified by the interrupt notification device is fetched, and the physical address in which the communication data packet is stored in the memory is fetched by the position/physical address conversion device.
