Other embodiments are also described and claimed. | 05-17-2012 |
20140072134 | ROBUST PROCESS FOR MANAGING FILTER COEFFICIENTS IN ADAPTIVE NOISE CANCELING SYSTEMS - A system for managing the changing state of an adaptive filter in an active noise control (ANC) system is described. An adaptive filter state storage stores copies of prior states of the adaptive filter. A disturbance detector can detect either normal ambient noise or abnormal ambient noise. An adaptive filter state manager signals that a copy of a current state of the adaptive filter is to be repeatedly written to the state storage, so long as normal ambient noise is being detected. But when abnormal noise is detected, the state manager signals that the adaptive filter be restored to one of its prior states, from the copies stored in the state storage. Other embodiments are also described and claimed. | 03-13-2014 |

20150293709 | FINE-GRAINED BANDWIDTH PROVISIONING IN A MEMORY CONTROLLER - Systems and methods for applying a fine-grained QoS logic are provided. The system may include a memory controller, the memory controller configured to receive memory access requests from a plurality of masters via a bus fabric. The memory controller determines the priority class of each of the plurality of masters, and further determines the amount of memory data bus bandwidth consumed by each master on the memory data bus. Based on the priority class assigned to each of the masters and the amount of memory data bus bandwidth consumed by each master, the memory controller applies a fine-grained QoS logic to compute a schedule for the memory requests. Based on this schedule, the memory controller converts the memory requests to memory commands, sends the memory commands to a memory device via a memory command bus, and receives a response from the memory device via a memory data bus. | 10-15-2015 |

20080243971 | METHOD AND APPARATUS FOR CALCULATING AN SSD AND ENCODING A VIDEO SIGNAL - The present invention relates to a method and apparatus for calculating the Sum of Squared Differences (SSD) between a source block and a reconstructed block of image or video data encoding according to an encoding scheme such as H.264/AVC. In a preferred embodiment, the method computes the SSD by finding the SSD between coefficients of an integer transformed residual block and the corresponding inverse-quantized coefficients. Preferably the inverse quantized coefficients are found with the aid of a look up table. This method may save computing time and processing power compared to calculating the SSD directly from the source and reconstructed blocks. The SSD is related to the distortion caused by encoding and the method may be used in calculating the rate-distortion of a particular encoding mode. One embodiment of the invention encodes a block of data by selecting the encoding mode with the least rate-distortion. | 10-02-2008 |

20090310875 | MOTION ESTIMATION METHOD - A motion estimation method uses a search start point and a plurality of search paths extending from the start point. The method finds an image point along the plurality of search paths that has a minimum comparison value with a reference image block. This image point with a minimum comparison value becomes the new search start point, with a plurality of new search paths extending from the new start point. The method then finds the image point along the plurality of new search paths that has a minimum comparison value with the reference image block. The cycle repeats until points on the search paths have comparison values higher than the start point. | 12-17-2009 |
