Abstract

PURPOSE:To attain the application of the software developed for a single processor also to the broadcast type service as it is, by adding a command reply control part to each processor and transferring an input command received only the input right is set to the own processor through each command reply control part in case the input command is broadcast from a certain processor. CONSTITUTION:A command supplied from an LAN (local area network) 1 is fetched to a buffer register 23 from an LAN interface part 21. A command analysis part 24 analyzes the command of the register 23 and carries out the following process according to the type of the analyzed command. While the input right validity is stored to a memory part 25 with a command to set an input device to a processor 5. It is decided whether or not an input is carried out by means of the contents of the part 25 with an input command. When said input is carried out, an input signal is transferred to the processor 5. While the input command within the register 23 is erased in case no input is carried out. Then the input command is transferred as it is to the processor 5 with an output command.

。There is so-called broadcast-type communication in which commands are sent to multiple distributed processing devices, and each processing device performs the desired processing.
