    摘要: Data transfer mode between a plurality of circuit mod modules connected to a data bus is dynamically switched between a time division, space-division multiplexing and so forth for improving data transfer efficiency. For example, the data bus of 4n bit width is used as two data bus of 2n bit width in certain period (transfer mode “b”), as one data bus of 4n bit width in a certain period (transfer mode “a”), and further as four data bus of n bit width in a further certain period (transfer mode “c”). A command of switching of the transfer mode is performed by a transfer control circuit common to respective circuit modules. In response to command of the transfer mode, switching of the bit width of data and switching of the bus connecting condition are performed by the bus adapter circuit.

It further has a monitoring module 12, an area unlocking module 13, a local accessing module 14, an area locking module 15, a search control machine 16, and a timer 17. A plurality of tasks (processes) are operating on a processor 18, and one memory 19 is commonly used by the plurality of tasks (processes). When a task (process) has secured a memory space (called a block here), free areas therein are managed by a group of pointers. A block is divided into a plurality of fixed length fields. A group of flags match the memory space (block) in one-to-one correspondence. The flag group indicate whether or not individual fields are being used, i.e. the flag group indicates whether each individual field is being used or unused (free).

    摘要: A transfer control table contains a source memory designation field, a desired region designation field, a shifting amount designation field, and a destination memory designation field. An source selection circuit selects source designation word data from the source word data stored in the source memory according to source memory designation data contained in the source memory designation field to provide the source designation word data. A transfer data bit operation circuit extracts, in response to the source designation word data, only the word data required for transfer as valid word data according to desired region designation data contained in the desired region designation field to shift the valid word data by a bit width that is predetermined based on shifting amount designation data contained in the shifting amount designation field and then to provide the shifted valid word data. A destination selection circuit selects which designation region in the destination memory the shifted valid word data are to be stored in and then provides the shifted valid word data to the designated area in the destination memory.

    摘要: A network system includes: a core switch; and an edge switch. The edge switch includes: a join message identification unit; and a marking unit. The join message identification unit identifies a join message from among MAC frames from the user network. The marking unit marks mark information to a header of a MAC-in-MAC frame in which the identified join message is encapsulated. The core switch includes: a plurality of input/output ports; a mark identification unit; and a port setup unit. The mark identification unit identifies a MAC-in-MAC frame in which a header is marked with the mark information. The port setup unit associates a multicast group of a join message which is encapsulated in the identified MAC-in-MAC frame, with an input/output port to which the identified MAC-in-MAC frame is input.
