20080303843 | METHOD AND DEVICE FOR GENERATING GRAPHIC IMAGES - A method generates an image from a set of image zones each delimited by a contour of polygonal shape defined by a set of vertexes, and comprising pixels having an attribute value which can be deduced from the value of a corresponding attribute of each of the vertexes of the image zone. The method includes determining to within a pixel the pixels that belong to each image zone according to the dimensions in number of pixels of the image to be generated; associating the pixels of each image zone in blocks of pixels; and determining an attribute value for each block of pixels of each image zone as a function of the value of the corresponding attribute of each vertex of the image zone. | 12-11-2008 |
20090257651 | COMPRESSION/DECOMPRESSION OF DIGITAL IMAGES - A method of compressing at least a part of a digital image comprises the steps of: dividing said digital image into groups of pixels; assigning a first information to each group of pixels wherein said first information indicates at least two reference colors selected for said group of pixels and, for each pixel in said group of pixels, which reference color or combination thereof is selected; assigning a second information to each group of pixels indicating a mode of compression used for said group of pixels; said first information indicating at least a third color for at least one of said groups of pixels. | 10-15-2009 |

20140327668 | Compression Format Conversion for Texture Data - A conversion between two texture compression formats comprises calculations performed at index-level for reducing handling of values with color bit-length and an amount of calculations with color values. Format conversion can thus be performed in real time upon displaying an image using the compressed texture data, without significant slowing down of a display rate of the images. It may be implemented in particular for conversion from DXT1—to ETC1 compression format, and a non-flipped or flipped orientation of an ETC1—compressed texture data block can thus be determined from said texture data block as initially compressed in DXT1 format. | 11-06-2014 |

20150058578 | ENHANCED PRE-FETCH IN A MEMORY MANAGEMENT SYSTEM - A memory management unit may send page table walk requests to a page table descriptor in a main memory system and receive address translation information, with the page table walk requests including information that specifies an amount of further address translation information, and receive the further address translation information. The cache unit may intercept the page table walk requests, and modify content of the intercepted page table walk requests so the information that specifies the amount of further address translation information is extended from a first amount to a second amount greater than the first amount. The cache unit may store the second amount of further address translation information for use with data requests that are subsequent to a current data request, and provide the address translation information based upon an intercepted page table walk request being associated with address translation information already stored in the cache unit. | 02-26-2015 |
20150081983 | PRE-FETCH IN A MULTI-STAGE MEMORY MANAGEMENT SYSTEM - A memory management system for managing a memory and includes a multi-stage memory management unit including control circuitry and cache memory. The cache memory may have a respective translation look-aside buffer for each stage of the multi-stage memory management unit. The control circuitry may be configured to generate a blank data request including a virtual address and information that specifies that data is not to be read from the memory, perform address translations based on the generated blank data request in multiple stages until a physical address is obtained, and discard the blank data request. | 03-19-2015 |

20130207837 | Method for Determining a Confidence Indicator Relating to the Trajectory Followed by a Moving Object - A method includes estimating the position of the moving object on the basis of the reception of navigation signals emitted by a constellation of satellites, the navigation signals being modulated by a code and the receiver comprising a local replica of the code. The determination of the confidence indicator consists in estimating a speed of displacement of the receiver over an identified trajectory segment, deducing therefrom a Doppler delay function corresponding to the motion of the receiver, in correcting the auto-correlation function of the GNSS navigation signal received from each satellite of the constellation by means of the delay function, in comparing the corrected auto-correlation function with a theoretical auto-correlation function by applying a quadratic criterion corresponding to the confidence indicator. | 08-15-2013 |
20140125521 | Method for Estimating the Direction of Arrival of Navigation Signals at a Receiver After Reflection by Walls in a Satellite Positioning System - A method includes estimating a position of a receiver, aboard a moving object, on the basis of the navigation signals emitted by satellites received by an antenna in an antenna array placed on the moving object, and using a three-dimensional geographical map to deduce, geometrically, on the basis of the position of the receiver and of a ray casting starting from the receiver, the number of paths reflected on walls of buildings present in a scene corresponding to an environment surrounding the receiver. The determined number of reflected paths is used to initialize an algorithm for estimating angles of arrival of multi-paths to deduce therefrom angles of arrival of the paths reflected on the walls before reaching the receiver. Optionally, the method can comprise making it possible to bound the distance information error due to a multi-path to render the estimation of direction of arrival of the signals more efficacious. | 05-08-2014 |
20140351667 | METHOD OF DECODING A CORRECTING CODE, FOR EXAMPLE A TURBO-CODE, BY ANALYSIS OF THE EXTENDED SPECTRUM OF THE WORDS OF THE CODE - An improved decoding method is provided making it possible to solve the problem of the error floor of a turbo-code or of an LDPC code, or more generally of a correcting code from the family of “turbo-like codes”, while preserving the same spectral efficiency, without any decrease in the useful throughput of the encoded stream. This result is obtained by an identification, on input to the decoder, of the bits on which an error has a strong impact, and a modification of the likelihoods corresponding to these bits so as to improve the convergence of the decoder. | 11-27-2014 |
20150249966 | GNSS Radio Signal For Improved Synchronization - A global navigation satellite system (“GNSS”) positioning method is provided, based upon a GNSS radio signal that comprises a navigation message transmitted as a succession of data packets. Each data packet is present in the GNSS radio signal as a sequence of symbols obtained by application of a code preceded by a synchronization symbol header. The data packets are organized internally into data fields. At least certain data packets of the succession of data packets contain a synchronization bit field translated by application of the code into a synchronization symbol pattern. | 09-03-2015 |
