Patent number: 7826582Abstract: A system and method for performing output clock phase smoothing. A phase smoothing circuit is described and includes a numerically-controlled oscillator (NCO) configured to produce a plurality of NCO clock pulses at a selectable frequency that is based on an input clock. Edges of the plurality of NCO clock pulses are aligned to edges of the input clock. A phase error calculation module is coupled to the NCO and is configured to generate a corresponding phase error for each of the plurality of NCO clock pulses. A clock phase selectable delay is coupled to the phase error calculation module and is configured to adjust each of the plurality of NCO clock pulses according to the corresponding phase error to generate an output clock at the selectable frequency that are phase-adjusted to more closely match an ideal output clock phase. Edges of the output clock need not necessarily align to the edges of the input clock.Type: GrantFiled: September 18, 2006Date of Patent: November 2, 2010Assignee: National Semiconductor CorporationInventors: Mark D.

Patent number: 7783105Abstract: A method and system for digitally scaling a waveform. A method is described performing a linear waveform transformation and translation of a curve in a smooth and continuous fashion. Another method is described for scaling a waveform in which the available accuracy and resolution is manipulated for a given waveform. Specifically, by strategically placing virtual tap points of a waveform, as well as changing the scaling factors used for calculating points on the waveform provides for adjusting the accuracy and resolution in one or more regions of a waveform. These scaling methods provide a digital equivalent of a voltage tap-based analog resistor ladder used for digital-to-analog conversion. The digital virtual tap points represent the analog voltage tap points, and the vertical translation of the curve acts in a smooth, monotonic, and continuous fashion.Type: GrantFiled: June 7, 2006Date of Patent: August 24, 2010Assignee: National Semiconductor CorporationInventors: Bruce C.

Patent number: 7471218Abstract: Various technologies for efficiently storing and retrieving streaming data are described. Bits of data (e.g., P bits of data) are received and separated into most significant bits (MSB) of data and least significant bits (LSB) of data. Further, the MSB of data and the LSB of data are respectively packed into a first word and a second word. The first word is stored in a first area of a frame buffer and the second word is stored in a second area of the frame buffer. As a result, data is managed in a more efficient way to reduce memory bandwidth requirement.Type: GrantFiled: September 18, 2006Date of Patent: December 30, 2008Assignee: National Semiconductor CorporationInventor: Mark D.

Patent number: 7382349Abstract: A method of operating a display includes operating a pixel of the display using a first signal to provide a first brightness level. A characteristic of the first signal is represented by a value in a range extending from a minimum signal value to a maximum signal value. A second brightness level is then selected and is different from the first brightness level. A truncated table is consulted and contains overdrive values for selected pairs of possible first and second brightness levels. The overdrive values are in a range extending from a minimum table value to a maximum table value, where the minimum table value is less than the minimum signal value or the maximum table value is greater than the maximum signal value or both. An overdrive signal is determined from the overdrive values of the truncated table based on the first and second brightness levels. The pixel is briefly operated using the overdrive signal to facilitate transition to the second brightness level.Type: GrantFiled: September 30, 2004Date of Patent: June 3, 2008Assignee: National Semiconductor CorporationInventor: Mark D.

Patent number: 7317775Abstract: A method and circuit capable of handling skew between a clock and data signal up to +/? one half bit on a random input data pattern. A digital algorithm cycles through each data bit and individually deskews that bit by detecting data transitions in a first sampling region and in a second sampling region and determining a difference between a number of transitions in the first sampling region and a number of transitions in the second sampling region. The sampling regions and a deskew timing signal may then be incremented or decremented based on a comparison of the computed difference to a predetermined constant. If no transitions occur on a particular bit, the algorithm times out leaving the deskew timing signal in the original position. When analysis of a final bit of a channel is completed, the algorithm begins monitoring and analyzing the first bit of another channel.Type: GrantFiled: July 16, 2004Date of Patent: January 8, 2008Assignee: National Semiconductor CorporationInventors: Richard Alexander Erhart, Loren Tomasi, Mark D.

Patent number: 6861886Abstract: A data/clock deskewing methodology uses a delay-locked loop (DLL) circuit. The DLL circuit generates a number of clock phases in response to an input clock, where each clock phase is delayed relative to the input clock signal. The clock phases are used to sample data from a data line. The sampled data is checked against a preamble pattern (a sequence of known data). A digital deskew control block selects one of the clock phases after analyzing the results of preamble pattern check such that subsequently received data is sampled with the appropriately selected clock phase.Type: GrantFiled: May 21, 2003Date of Patent: March 1, 2005Assignee: National Semiconductor CorporationInventors: Christopher A.
