Abstract: A method of encoding video data including a sequence of digital image frames, in a pipelined processing system is provided. The method includes dividing each frame in the sequence into a plurality of sections, each section including a horizontal band across a frame. The method further includes subdividing each section into a plurality of macroblocks, and encoding a representation of each macroblock in each section to form an output stream. The sections of each frame are processed during adjacent steps in a pipeline of the pipelined processing system.

Abstract: A method allows changing an image raster direction from an application raster direction to a screen raster direction, in-flight while pixel values of an image are transferred successively from an application output memory to a display unit. A single buffer memory array is implemented between the application output memory and the display unit. Two writing orders for cells of the buffer memory array are used in turn, each being combined with a different reading order for the cells. The method can be hardware-implemented, and is adapted for burst-handling of the pixel values.

Abstract: A method for determining a symbol boundary in a data packet belonging to a received OFDM signal is provided. The data packet includes a first training filed and a second training field, which begins with a guard interval. The method includes detecting the beginning of the data packet, and starting an automatic gain control process. The method further includes, after the automatic gain control process is locked, determining autocorrelation peaks and estimating the symbol boundary from times of the autocorrelation peaks.

Abstract: An output stage configuration with four configurable input/output terminals and four switches is specified. Each switch has a first main terminal, a second main terminal and a control terminal, which receives a control signal for controlling the open or closed state of the switch. The output stage is included in a circuit together with a first control apparatus and a second control apparatus. When a control stage of the first control apparatus is connected to the output stage, a control stage of the second control apparatus is electrically disconnected from the output stage, and the output stage operates in a first operating state. When the control stage of the second control apparatus is connected to the output stage, the control stage of the first control apparatus is electrically disconnected from the output stage, the output stage then operating in a second operating state.

Abstract: A receiver for an N-wire digital interface, where N is any integer exceeding two, has N input terminals, a common node and N detection stages. Each of the N detection stages has a resistive element coupled between the common node and a respective one of the N input terminals, and a comparator having a first input coupled to the respective one of the N input terminals and a second input coupled to the common node.

Abstract: A method and an apparatus determine a time of start of series of OFDM symbols forming an OFDM packet, wherein one or more symbols of the OFDM signal includes a plurality of copies of a short training sequence made of a plurality of time-domain samples. The method includes determining a coarse time index, determining a fine time index, and determining the time of start of each OFDM symbols based on the fine time index. The coarse time-domain sample of the coarse time index is within a coarse estimation error interval, and the time-domain samples of the coarse estimation error interval are converted into frequency domain samples. A metric value is determined for each frequency domain samples, and the fine time index is the time index corresponding to one of the coarse estimation error interval having its associated frequency domain sample having the lowest metric value.

Abstract: A Near Field Communication method performed by a tag reader detects whether a tag is present. The method includes stimulating the tag reader's transmitter to generate an impulse response, evaluating the impulse response generated by the transmitter to obtain an evaluated impulse response, and assessing whether a tag is present based on the evaluated impulse response.

Abstract: A system for delivering a voltage to at least one power domain has at least one component. Each power domain functions according to at least two operating points, each operating point requiring a distinct supply voltage. The system includes at least two power supply units, alternatively delivering controllable supply voltages. The system also includes a control unit that selects one of the power supply units to be connected to a power domain, based on a current operating point of the power domain. The control unit also controls the supply voltage delivered by the selected power supply unit, to deliver the required voltage level associated with the current operating point of the power domain.

Abstract: A system for measuring an output current of a DC-to-DC converter with a transistor power stage includes a voltage measuring circuit and an impedance. The voltage measuring circuit, which is connected to the output of the power stage of the DC-to-DC converter, measures an average voltage drop on impedances of the transistors of the power stage. The impedance, which is connected to an output of the voltage measuring circuit, reproduces the impedances of the transistors of the power stage and is traversed by a scaled version of the current output of the voltage measuring circuit.

Abstract: An efficient way is described for a user equipment, camping on a cell of a first radio access technology, RAT, to perform measurements on the transmissions from a neighboring radio cell of a different RAT. Recurrent time gaps that are available for making the measurements are not correlated or synchronized with the recurrent times at which the desired information are transmitted by the transmitter in the second RAT. Therefore, mapping is performed of the time gaps onto the interval at which the desired information is transmitted. The mapping continues until a time interval is covered that ensures that the information in the recurring desired block of information can be obtained. During the mapping of the measurement gaps, only those time intervals that have not already been covered by the mapping are used for obtaining the desired information.
