Abstract:
A decoding circuit and associated method are provided for decoding a biphase signal. The decoding circuit may include a precharging register to precharge a pair of states of the biphase signal, where a state of the pair of states is precharged at each pulse of a periodic precharging signal. The decoding circuit may further include a verification circuit to compare the two states of the pair of states and give an active error signal if the two states are equal.
Abstract:
The disclosure relates to a method for executing by a processor an instruction for saving/restoring several internal registers of the processor. The method comprises breaking down the saving/restoring instruction to generate micro-instructions for saving/restoring the content of a register, executing each of the micro-instructions, initializing a progress status of the saving/restoration of the registers, updating the progress status of the saving/restoration upon each generation of a micro-instruction for saving/restoring a register, saving the progress status in the event of an interruption in the saving/restoration of the registers to execute a higher-priority task, and restoring the progress status when the saving/restoration of the registers is resumed.
Abstract:
The invention relates to integrated circuits for microwave applications in the millimeter wavelength range (frequencies of around 50 GHz). To improve the performance of the microwave transmission lines in the circuit, a structure of conducting vias between a transmission line and a conducting zone is proposed. The vias are formed in apertures in a benzocyclobutene layer. These apertures are larger at their base than the conducting zones. The transmission line descends into the aperture but does not come back up over the edges of the aperture. The parasitic capacitances with the substrate at the point of contact are minimized.
Abstract:
A method and device are provided for synchronizing the presentation of audio frames and/or of video frames comprises the detection of presentation time stamps in a stream of frames. The presentation instant indicated by a time stamp is compared with a time delivered by a local reference clock. Depending on a variance and on an average of values of deviation between presentation instants and corresponding times indicated by the clock, the clock can be initialized according to the presentation instant indicated by a time stamp or the presentation of the frames can be adjusted.
Abstract:
An electronic circuit includes configurable cells with a test input and an output. The configurable cells are capable of being connected to one another in a chain in a predefined order via the test inputs and the outputs to form a test shift register if they receive a chaining command signal. A connection control module disconnects the test input from at least one configurable cell if the connection control module receives an invalid identification key. The connection control module leaves disconnected the test input from the at least one configurable cell, or applies a constant potential on the test input of the at least one configurable cell, or connects the test input of the at least one configurable cell at an output of a random-data generator.
