  • Multi-phase power system with redundancy
    Patent number: 8901909
    Abstract: An integrated circuit device for delivering power to a load includes a controller circuit, a cascade circuit, and a power delivery circuit. The controller circuit generates a plurality of control signals. The cascade circuit receives the control signals from the controller circuit and sequentially outputs the control signals onto a cascade bus. The power delivery circuit receives the control signals from the controller circuit and delivers an amount of current to the load, in response to one of the control signals.
    Type: Grant

  • Regular expression search engine
    Patent number: 7656716
    Abstract: A system for searching an input string for a number of regular expressions includes a search block and a compiler. The search block includes a plurality of content addressable memory (CAM) devices, wherein each of the CAM devices is differently configured to implement search operations for regular expressions having a unique level of complexity. The compiler is configured to determine the complexity level of each of the regular expressions, and is configured to store each regular expression in a selected one of the CAM devices according to its complexity level.
