Publication number: 20100328538Abstract: Various exemplary embodiments relate to a method and related motion estimation unit for performing motion estimation on video data comprising a plurality of frames. The method may begin by reading a current frame of the plurality of frames from a memory of a motion estimation unit. The method may then select a motion vector for each respective block of pixels in a current row of the current frame. The step of selecting the motion vector may include, for each respective block, selecting, by the motion estimation unit, a candidate vector for at least one block directly surrounding the respective block based on a determination of whether the directly surrounding block has been processed for the current frame, calculating, for each candidate vector, a difference value, and selecting, as the motion vector, the candidate vector with the lowest difference value.Type: ApplicationFiled: October 5, 2009Publication date: December 30, 2010Applicant: NXP B.V.Inventors: Ghiath Al-Kadi, Andrei Sergeevich Terechko, Jan Hoogerbrugge, Abraham Karel Riemens, Klaas Brink

Publication number: 20100328147Abstract: A system implements a location based service, and comprises a satellite navigation receiver implementing a position tracking function for providing the location of a user of the service. An analogue rf receiver (12) receives satellite signals and performs at least a frequency downconversion. Correlation and decoding functions are applied to the downconverted signals for deriving location information from detected specific satellite signals. The system further comprises a server (30) for receiving samples of the downconverted signals, and for verifying the samples are consistent with the expected satellite signals at that time and location. The invention provides a counter measure for detecting the counterfeiting of, or tampering with, the satellite signals at the receiver.

Publication number: 20100332759Abstract: A program is obfuscated by reordering its instructions. Original instruction addresses are mapped to target addresses. A cache efficient obfuscated program is realized by restricting target addresses of a sequence of instructions to a limited set of the disjoint ranges (33a-d) of target addresses, which are at lease half filled with instructions. Mapped address steps (34) are provided between the target addresses to which successive ones of the original instruction addresses are mapped. The address steps (34) include first address steps within at least a first one of the mutually disjoint ranges (33a-d). Between said first address steps, second address steps within at least a second one of the mutually disjoint ranges (33a-d). Thus, a deviation from successive addresses for logically successive instructions is realized.Type: ApplicationFiled: February 9, 2009Publication date: December 30, 2010Applicant: NXP B.V.Inventor: Marc Vauclair

Publication number: 20100329156Abstract: A multi-protocol, multi-standard, software-defined radio (SDR) includes one or more RF front ends to support each radio frequency band, and a programmable processor that replaces special-purpose hardware for the tuning and demodulation of each radio service. The programmable processor has limited peak processing capabilities, and calculations are made to see if present user terminal assignments will result in processing conflicts that could exceed the peak processing capabilities. In traffic slot applications in particular, any possible simultaneous arrival or overlap of traffic slots from the respective radio services is projected. If conflicts will result from the current user terminal assignments, then those assignments are reshuffled to obtain a non-conflicting result.Type: ApplicationFiled: February 18, 2009Publication date: December 30, 2010Applicant: NXP B.V.Inventors: Yanmeng Sun, Liangliang Hu

Patent number: 7859314Abstract: Edge-rate control circuits and methods are implemented using a variety of arrangements and methods. Using one such method, an output signal of a bus is controlled by decoupling a feedback capacitor (116) from a gate of a transistor (108) using an isolation switch (106). The transistor (108) is used to control the output signal. A predetermined amount of charge is removed from the feedback capacitor (116) using a charge distribution capacitor (114) that is selectively coupled to the feedback capacitor (116) using a switch (112). The switch (112) is enabled in response to the output signal reaching an output voltage and disabled in response to the charge distribution capacitor (114) reaching a reference voltage.Type: GrantFiled: March 31, 2007Date of Patent: December 28, 2010Assignee: NXP B.V.Inventors: Joseph Rutkowski, Alma Anderson
