Abstract: PURPOSE: A method for calculating a checksum of a TCP segment/UDP data gram during IPv4(Internet Protocol version 4)/IPv6(Internet Protocol version 6) translations is provided to implement a required checksum value without including a value of a newly specified data area while calculating a checksum, thereby reducing a time for calculating the checksum value. CONSTITUTION: A TCP segment of an IPv4-based network is received through a receiving processor(S2001). A checksum reader reads a checksum within a TCP header, and a receiving pseudo header area checksum processor and a receiving header area checksum processor operate values of a pseudo header and a header area(S2002). A complement translator translates the read checksum to a complement of '1'(S2003). An adder adds the operated values of the pseudo header and the header area(S2004). A pseudo header area checksum processor and a header area checksum processor operate values of a pseudo header area and a header area of a packet, respectively(S2005-S2006). Another adder adds the operated values to the operated values of the receiving checksum processor, and translates the added value to '1' by another complement translator, to obtain a new checksum(S2007-S2008). A checksum insertion processor inserts the new checksum value to a newly translated TCP header, to transmit the value to an IPv6-based network(S2009).

Abstract: A differential cascode structure is configured to propagate a data state to a static latch at each active edge of a clock. A clock generator enables the communication of the data state and its inverse to the latch for a predetermined time interval. In a first embodiment, each cascode structure includes three gates in series, the gates being controlled by the clock signal, a delayed inversion of the clock signal, and the data state or its inverse. In an alternative embodiment, each cascode structure includes two gates in series, the gates being controlled by the clock signal and the delayed inversion of the clock signal. In this alternative embodiment, each of these cascode structures is driven directly by the data signal or its inverse. The static latch obviates the need to precharge nodes within the device, thereby minimizing the power consumed by the device. The latch preferably comprises cross-coupled inverters, which, being driven by the differential cascode structure, enhance the switching speed.
