摘要： There is described a method for establishing an NFC connection between a subscriber identity module (SIM) and an NFC device (RDR). The subscriber identity module (SIM) is connected to a telecommunications system (CELL_P) through contacts (VCC, RST, CLK, D+, GND, SWP, IO, D−) of the telecommunications system (CELL_P). The telecommunications system (CELL_P) comprises a chipset (CHP) and an NFC circuit (NFCC). The method comprises measuring the level of charge of a battery (BATT) powering the telecommunications system (CELL_P) with a battery gauge. Based on the measurement, the method selects the source for supplying power to the subscriber identity module (SIM) and configures the wiring of the subscriber identity module (SIM). The disclosure also relates, in particular, to a telecommunications system, to a computer program, and to a storage medium.

摘要： In an embedded system, there are a plurality of data requesting devices, a plurality of data sources and a bus fabric interconnecting the data requesting devices and the data sources, wherein the bus fabric comprises a plurality of bus components. Some or all of the data sources and arbitration devices associated with the bus components resolve contentions between data bursts by selecting a first one of the contending data bursts; determining a length of a critical section of the first selected data burst; and processing the critical section of the selected data burst. Then, a second one of the contending data bursts is selected, a length of a critical section of the second selected data burst is determined, and the critical section of the second selected data burst is processed before a non-critical section of the selected data burst.

摘要： The present invention relates to a method of managing switching from a first mode of operation to a second mode of operation a first processor in a processing device which comprises at least one other processor and a controller processor. The method comprises receiving a message which comprises a request to switch the first processor from a first to a second mode of operation; deciding whether the switching is appropriate; and upon decision of switching, switching the first processor from a first mode of operation to a second mode of operation according to the selected type of switching.

摘要： A built-in self-testing method of a near field communication device including several functions tests a first internal communication link between a first function and a second function. The testing is performed by sending, on said first internal communication link, a first command from said first function used as a transmitter to said second function used as a receiver, and by checking said first command has been correctly executed by said second function.

摘要： An amplifier has an input port for receiving an input signal and an envelope port for receiving an envelope signal indicative of an envelope of the input signal, and an output port for delivering an amplified signal. The amplifier has a first transistor and a second transistor. A first biasing circuit is coupled to the envelope port and is arranged to generate a first bias voltage dependent on the envelope signal. A summing stage is coupled to the input port for receiving the input signal, to the first biasing circuit for receiving the first bias voltage, and to the gate of the first transistor. A second biasing circuit is coupled between the envelope port and the gate of the second transistor, and is arranged to generate a second bias voltage dependent on the envelope signal.

摘要： An apparatus (300) for use in a telecommunications system is disclosed. The apparatus (300) comprises a memory (340) and a controller (310). The apparatus (300) is configured to receive a radio frequency signal (150), determine an operating parameter and adapt a first filter function according to at least said operating parameter. The apparatus (300) is further configured to generate a filtered signal (720, 820, 730, 830) by applying said first filter function to a signal associated with the received radio frequency signal and provide said filtered signal (720, 82, 70, 830) for radio resource management.

摘要： A method in a Just-In-Time, JIT, compiler for compiling code in a JIT-compiler for a heterogeneous multiprocessor system is provided. The method comprises compiling a snippet of input code, whereby one or more compiled code snippets are generated for the snippet of input code. The one or more compiled code snippets are tagged with one or more snippet specific characteristics. One or more compiled code snippets are selected from the compiled code snippets, based on said snippet specific characteristics. The one or more selected compiled code snippets are executed on one or more of the plurality of processors. While executing, run-time data is gathered, where the gathered data is tagged for which processor in the heterogeneous multiprocessor system it is related to.

摘要： A temperature sensor includes two branches, each branch having at least a first transistor and a second transistor connected as diodes and cascaded, so that an emitter of the first transistor is connected to a collector of the second transistor of the same branch. The temperature source also includes a current source configured to provide a current to the two branches, and an analog-to-digital convertor. The analog-to-digital convertor is connected to capture a voltage between emitters of the first transistors or of the second transistors, and is configured to convert said voltage to a digital temperature signal.
