  • Patent number: 6798687
    Abstract: A system and method for effectively implementing a high-speed DRAM device may include memory cells that each have a bitline for transferring storage data, a wordline for enabling an accelerated-write operation in the memory cell, and a data storage node with a corresponding cell voltage. An accelerated-write circuit may then directly provide the storage data to an appropriate bitline in a pre-toggled state in response to one or more accelerated-write enable signals. The corresponding cell voltage may therefore begin a state-change transition towards the pre-toggled state immediately after the wordline is activated to successfully reach a full-state level before the wordline is deactivated during a high-speed memory cycle.

  • Patent number: 6788350
    Abstract: An apparatus and method for effectively implementing a unified clock-recovery system includes an analog frontend module that is configured to generate an analog-source timing reference signal that is based upon analog-source data. Similarly, a digital frontend module may extract a digital-source timing reference signal based upon digital-source data. A switch module may then select between the analog-source timing reference signal and the digital-source timing reference signal to thereby provide a selected input timing reference signal to a unified backend clock recovery module. The backend clock recovery module may then compare the selected input timing reference signal with an output timing reference signal in order to generate a timing error for advantageously adjusting a local clock to thereby compensate for the foregoing timing error.

  • Patent number: 6788813
    Abstract: A system and method for effectively performing a white balance operation preferably includes an electronic camera device that captures image data using a image sensor device. A color manager may then analyze the image data to selectively locate one or more neutral areas in the image data.

  • Patent number: 6753856
    Abstract: A system and method for dynamically correcting display characteristics to compensate for non-uniformities is disclosed. In the preferred embodiment, the display screen is divided into logical tiles, and then the initial correction parameters of the characteristics under consideration, namely convergence, brightness, hue, and beamlanding, are measured at the vertices of each tile. The dynamic correction circuitry automatically synchronizes the correction waveforms, which are functions of the locations on the physical display screen, with the control signals of the displayed image. Due to the synchronization, the previously stored initial correction parameters of the characteristics under consideration may be used to dynamically correct for uniformity of these characteristics. The preferred embodiment performs linear vertical and horizontal interpolation on the correction values between the vertices of the tiles.

  • Patent number: 6751588
    Abstract: A method for performing microphone conversions in a speech recognition system comprises a speech module that simultaneously captures an identical input signal using both an original microphone and a final microphone. The original microphone is also used to record an original training database. The final microphone is also used to capture input signals during normal use of the speech recognition system. A characterization module then analyzes the recorded identical input signal to generate characterization values that are subsequently utilized by a conversion module to convert the original training database into a final training database. A training program then uses the final training database to train a recognizer in the speech module in order to optimally perform a speech recognition process, in accordance with the present invention.
