    • A vehicle step-up converter circuit capable of preventing an excessive current from flowing in electric components and quickly regulating the step-up voltage. The vehicle step-up converter circuit comprises a battery; an inductor, one terminal of which is connected to one terminal of the battery; a first switch connected between the other terminal of the inductor and the other terminal of the battery; a second switch, one terminal of which is connected to the other terminal of the inductor; a capacitor connected between the other terminal of the second switch and the other terminal of the battery; and a switch control unit that controls the first and second switches; wherein the first and second switches are controlled, thereby charging the capacitor to output the voltage held by the capacitor. The switch control unit controls the second switch on and off at a predetermined duty ratio, thereby regulating the output voltage.

    • A data queue controlling apparatus including a plurality of input interfaces and a method of controlling the data queue controlling apparatus is provided. The apparatus performs effective data queue controlling without use of a single common data queue and solves the problems in LSI yield, operation frequency and power consumption by providing a plurality of data queues which are less than the number of input interfaces and also providing a means for equally sharing the packet data inputted from each input interface to each data queue.
    • 提供一种包括多个输入接口的数据队列控制装置和一种控制数据队列控制装置的方法。 该装置在不使用单个公共数据队列的情况下执行有效的数据队列控制,通过提供小于输入接口数量的多个数据队列来解决LSI产量,操作频率和功耗中的问题,并且还提供用于 将从每个输入接口输入的分组数据均等地共享到每个数据队列。
