  • Patent number: 9112520
    Abstract: A transmission interface includes a first pin, a second pin, a conversion unit, and a decoding unit. The conversion unit receives a serial input data stream via the first pin and receives a serial clock via the second pin. The conversion unit converts the serial input data stream to parallel input data and converts the serial clock to a parallel clock. The serial input data stream has a full swing form. The decoding unit receives and decodes the parallel input data and generates an input data signal according to the decoded parallel input data.

  • Patent number: 7561585
    Abstract: The speed of the network address translation translated with software is generally slower than the speed of transmitting packet in the network, so that the data stored in memory is affected. In this invention, the network address translation is translated by hardware, and a plurality of comparing engines is employed to accelerate the translating speed. Therefore, even in the worst case scenario, the time needed for translating the network address is shorter than the time needed for storing the packet into memory, so that the operation of the network address translation is assured not to affect the data transmission in the network.

  • Patent number: 7219177
    Abstract: A method and an apparatus in a computer system for connecting buses with different clock frequencies are provided. The method comprises receiving a request transmitted from a master to a slave. If the clock frequency of the master is lower than that of the slave such that the slave sees more requests than the master does, redundant cycles of the request signal are masked lest the slave repeatedly receive the request. The request is then transferred to the slave. If the clock frequency of the master is higher than that of the slave such that the slave cannot receive the request in time, then the request signal is lengthened so that the request signal is synchronized with the clock cycles of the slave. The output data responded from the slave is then transferred to the master.
