  • Publication number: 20100271502
    Abstract: Pixels of an image (200) are coded as colour vectors specified by RGB values. The image (200) is filtered by calculating new colour vectors for the pixels on a pixel by pixel basis. A new colour vector for a subject pixel (201) is calculated from the average of neighbour pixels (203) in a window (202) around the subject pixel (201). A first threshold is calculated from the standard deviation of the colour vectors of the neighbour pixels (203) in the window (202). A second threshold is calculated from the median maximum difference between the values defining the colour vectors of the respective neighbour pixels (203) in the window (202) and the standard deviation of the values. Only neighbour pixels (203) having a colour vector that differs from the colour vector of the subject pixel (201) by less than or the same as the first and second thresholds are used in calculation of the new colour vector for the subject pixel (201).

  • Publication number: 20100270997
    Abstract: A reference voltage that is consistent over various operational conditions and uses low power is provided. According to an example, an internal temperature-compensated voltage (e.g., vdd_int in 200) is generated from a power supply (e.g., vdd in 200), and a reference voltage (e.g., vref in 200) is generated from the internal voltage. The reference voltage is stored on a storage circuit (e.g., 430) that is coupled (charged) and refreshed under conditions, relative to circuit characteristics, that make low and ultra-low power operation possible.

  • Publication number: 20100273429
    Abstract: The present invention relates to a method of and arrangement for determining non-linear behavior of a device (40) under test, wherein the device (40) is excited by a test signal on relevant device terminals under different termination conditions and the emitted signals at the fundamental and harmonic frequencies are measured at the relevant device terminals. Then, calibration measurements taken on calibration standards of known impedance and linearity are performed to derive parameters needed to correct the raw data read by the measurement for cable loss and delay and for non-linear behavior of the measurement system. Finally, non-linear scattering or admittance parameters are extracted from the error corrected measurements taken at different excitation and termination conditions. Thereby, the non-linear behavior can be more accurately characterized, modeled and understood.

  • Publication number: 20100268910
    Abstract: A data processing system comprises multiple data processing nodes that communicate with one another using the FlexRay protocol. Each respective node works according to a respective schedule based on a repetitive sequence of cycles, each cycle having a sequence of time slots. Each node executes instructions, one per time slot, if any. The instructions are stored in a memory. Each instruction is identified by the relevant cycle number and time slot number in the relevant cycle. Accordingly, the combination of cycle number and slot number identify a memory address. Typical instructions appear more than once in the repetitive sequence of cycles for a node. This temporal pattern of occurrences of the same instruction at a node is used to modify the generation of the memory addresses, so that the same memory address is generated each time the instruction is needed. This makes efficient use of storage space.
