Patent number: 7561585Abstract: 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.Type: GrantFiled: March 31, 2003Date of Patent: July 14, 2009Assignee: Nuvoton Technology CorporationInventors: Ming-Jun Chiang, Chih-Chieh Chuang, Chun-Yu Chen, Chun-Nan Li, Ishemel Chang

Patent number: 7219177Abstract: 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.Type: GrantFiled: November 23, 2004Date of Patent: May 15, 2007Assignee: Winbond Electronics Corp.Inventors: Hen-Kai Chang, Chung-Wen Kao, Chih-Chieh Chuang, Chun-Nan Li, Te-Tsoung Tsai, Hsi-Yuan Wang
