  • Publication number: 20080143410
    Abstract: A clock input/output device has three-state inverters Iv1 to Iv3 and an inverter Iv4, which cooperate to make equal the on-state resistance through a supply-voltage-side (VDD-side) transistor and the on-state resistance through a ground-voltage-side (0-side) transistor so as to make equal to VDD/2 the threshold voltage with reference to which the clock input/output device evaluates the input thereto to determine whether or not to change the state of the output thereof.

  • Publication number: 20070118896
    Abstract: A network attack mitigation device defends a victim device against an attack from an attacker device while collaborating with other network attack mitigation devices. When the attack ends, the network attack mitigation device decides whether to terminate mitigation measure taken against the attack. This decision is made based on a status of other network attack mitigation device that is nearer to the attacker device than the network attack mitigation device. When deciding not to prepare for resume of the attack, the network attack mitigation device deletes information relating to the attack and returns to a normal state. When deciding to prepare for resume of the attack, the network attack mitigation device prepares to resume of the attack without deleting the information relating to the attack.

  • Patent number: 7216249
    Abstract: A clock generation system for generating a first-, a second-, and a third-reference frequency clocks having respective frequencies having predetermined ratios to the reference frequency of a reference clock, using PL circuits in such a way that the clocks have sufficient S/N ratios in spite of the S/N ratio limitation by the noise floor. A first reference frequency clock is supplied to a first PLL circuit to generate an intermediate-frequency clock having an intermediate frequency having a predetermined ratio to the reference clock. The intermediate-frequency clock is supplied to a second and a third PLL circuits to generate a second and a third reference frequency clocks having frequencies respectively having a second and a third ratios to the intermediate frequency, respectively.
