Abstract: One node is selected from a plurality of candidates for a bus management nod e. A bus management node 11 has a register for channels in use REG 1 and a bus capacity register REG2. Before starting the synchronous communication, each node 12 transmits a read-out command to the register for channels in use REG 1 and t he register for channels in use REG1 in order to read out their contents for ascertainin g the number of the un-used channel and the residual capacity. If there is any un- used channel and any residual bus capacity, the node 12 transmits write commands to these registers REG 1 and REG2 so that the number of the channel to be in us e and the capacity of the bus to be in use will be stored in the register for channels in use REG 1 and the bus capacity register REG2. This enables bus management to be achiev ed easily in a system performing synchronous communication between plural nodes connected to the bus.

Abstract: In a communication system, isochronous data can be continuously received without any interruption, and also asynchronous data irregularly transmitted can be received in a signal receiving apparatus. The signal receiving apparatus is arranged by comprising isochronous data being regularly transmitted; asynchronous data being irregularly transmitted; a common bus for transferring the isochronous data and the asynchronous data thereon; and temporary storage means for writing therein the received isochronous data and the received asynchronous data, respectively.

Abstract: A bus management node (11) is provided with a used-channel register REG1 and bus capacity register REG2. Before starting synchronous communication, each node (12) transmits a read instruction to the registers REG1 and REG2 to read their contents so as to check for available channels and bus capacity. When an unused channel exists and a bus capacity remains, the node (12) transmits a write instruction to the registers REG1 and REG2 so that the number of used channels and the capacity of used buses can be respectively stored in the registers REG1 and REG2. Therefore, buses can be managed by a simple method in a system which performs synchronous communication among a plurality of nodes connected to the buses.

Abstract: A bus management node 11 has a register for channels in use REG1 and.a b us capacity register REG2. Before starting the synchronous communication, each node 12 transmits a read-out command to the register for channels in use REG1 and the register for channels in use REG1 in order to read out their contents for ascertaining the number of the un-used channel and the residual capacity. If there is any un-used channel and any residual bus capacity, the node 12 transmits write commands to these registers REG1 and REG2 so that the number of the channel to be in use and the capacity of the bus to be in use will be stored in the register for channels in use REG1 and the bus capacity register REG2. When carrying out the writing in REG1 an d REG2, the node 12 compares read channel state information and read bus sta te information read out by the read-out command with channel state information and bus state information in REG1 and REG2 respectively. If the read channel information and the bus state information are identical to the channel state information and the bus state information in REG1 and REG2 respectively, it writes new channel information and new bus state information. This makes it possible to elimina te the possibility of wirting by other nodes.
