    • An information processing apparatus linked to a network includes a central processing unit CPU, a power management unit, a physical layer, a packet engine unit, a packet filter, and a transmission control unit. The packet engine unit transmits a packet to the network. The packet filter receives a packet from the network. The transmission control unit controls packet transmission. The power management unit supplies power to the physical layer, packet filter, and packet engine unit but not the CPU during a low-power mode. The packet engine unit includes an identification data generator, a message data generator, and a packet frame generator. The identification data generator generates identification data. The message data generator generates message data. The packet frame generator generates a packet by combining the identification data and message data. The transmission control unit transmits the packet periodically during the low-power mode.
    • 链接到网络的信息处理装置包括中央处理单元CPU,功率管理单元,物理层,分组引擎单元,分组过滤器和传输控制单元。 分组引擎单元向网络发送分组。 分组过滤器从网络接收分组。 传输控制单元控制分组传输。 电源管理单元在低功耗模式下为物理层,数据包过滤器和数据包引擎单元供电,但不为CPU供电。 分组引擎单元包括识别数据生成器,消息数据生成器和分组帧生成器。 识别数据生成器生成识别数据。 消息数据生成器生成消息数据。 分组帧生成器通过组合识别数据和消息数据来生成分组。 传输控制单元在低功率模式期间周期性地发送分组。

    • In a data transfer apparatus a clock transmitting unit transmits a first clock to a target for data transfer that is situated at a distance from the data transfer apparatus, a data transmitting unit in synchronization with the first clock transmits data including a start signal to the target; a response receiving unit receives from the target a response having therein the start signal and outputs a first response based on the response received; a clock generating unit receives the first clock and generates a second clock based on the first clock; a response generating unit in synchronization with the second clock generates a second response based on the first response; and a selector selects any one of the first response and the second response depending on the distance.
    • 在数据传送装置中,时钟传送单元将第一时钟发送到距离数据传送装置一定距离的数据传送目标,与第一时钟同步的数据发送单元向目标发送包括起始信号的数据 ; 响应接收单元从目标接收其中具有起始信号的响应,并且基于接收到的响应输出第一响应; 时钟发生单元接收第一时钟并基于第一时钟产生第二时钟; 与第二时钟同步的响应产生单元基于第一响应产生第二响应; 并且选择器根据距离选择第一响应和第二响应中的任何一个。
