    摘要: A bus management node 11 has a register for channels in use REG1 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 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. This enables bus management to be achieved easily in a system performing synchronous communication between plural nodes connected to the bus.

    摘要: A data demultiplexer includes a write controller, a memory, an analyzing processing unit, and transfer control units. The write controller writes packets which have arrived thereat into the memory in the order of arrival and sends the write information to the analyzing processing unit. The analyzing processing unit analyzes packets in the order of arrival on the basis of the write information and sends only the result of analysis to the transfer control units. On the basis of the result of analysis, the transfer control units send data read from the memory in the order of packet arrival to the decoder. A data demultiplexer capable of reducing the processing in the analyzing processing unit can be provided.

    摘要: A method of testing an electronic apparatus which eliminates a control signal line for setting an integrated circuit to a test mode and a test mode select terminal of an external terminal section and wherein fetching of test data and transfer of the thus fetched test data are performed in an integrated operation. In each of the integrated circuits, a boundary scan control circuit discriminates a category code at the top of data inputted from a serial input terminal to control a pair of switching circuits. When the category code represents a test mode, predetermined terminals of the switching circuits are selected so that input data are sent out to boundary scan cells. Fetching of parallel data from parallel input terminals and transfer to the boundary scan cells are performed at a time.
