  • Patent number: 9542341
    Abstract: 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.

  • Patent number: 9525669
    Abstract: A method in a first device for anonymously delivering data to a part that has initiated a task is provided. The first device and the part initiating a task are participants in opportunistic sensing. The method comprises creating a data sample and encrypting the data sample with a public key of the task initiating part. After communicating the protected sample to one or more intermediate devices, one of the one or more intermediate devices delivers the protected sample to the task initiating part, such that the task initiating part does not know the identity of the first device. The task initiating device only know the identity of the one of the one or more intermediate devices that delivered the protected sample to the task initiating part, wherein the intermediate devices are participants in the opportunistic sensing.

  • Patent number: 9515945
    Abstract: Methods of changing a data rate of communication over an interface between a data transmitter and a data receiver are disclosed, wherein the data transmitter is associated with a first processor and transmitting data over the interface and the data receiver is associated with a second processor. The data transmitter transmits and the data receiver receives data over the interface at a first data rate. At the first processor, it is determined to change the first data rate to a second data rate. The data transmitter transmits and the data receiver receives a request to change the first data rate to the second data rate. In response thereto, a response message is transmitted by the data receiver and received by the data transmitter. When the response message comprises an acknowledgement to change the first data rate to the second data rate, the data transmitter transmits and the data receiver receives data over the interface at the second data rate.

  • Patent number: 9510213
    Abstract: Methods and systems for performing interference mitigation (immunity management) in a radio communication device. A list of frequencies is provided from at least one radio subsystem to an immunity management (IMM) module. The IMM module determines whether any of the frequencies in the list represent a conflict with harmonics associated with one or more clock frequencies associated with one or more embedded systems. If a conflict exists, then the IMM module makes a change in the fundamental frequency of the corresponding clock to remove the conflict, while also ensuring that other frequencies in the list are not impacted by the change. The potential need to change clock frequencies can be evaluated at state transitions of the device, e.g., call establishment, call release, handover or channel re-allocation events.

  • Patent number: 9504010
    Abstract: A wireless communication apparatus, which is configured to receive and transmit data via cells of at least two network cell belonging different networks, selects one of the networks to listen to in case of conflict. The apparatus has a radio transceiver module and a processor. The processor includes a driver of the radio transceiver module to choose one network that the radio transceiver module should listen to, a pattern detector configured to obtain a paging block repetition pattern for each of the networks, and a conflict manager configured to select the network to listen to when paging blocks from different networks collide. The conflict manager selects the network based on the paging block repetition patterns to minimize the probability of loss of a paging message associated to the paging blocks by predicting the next paging block transmissions.

  • Patent number: 9496917
    Abstract: An accumulation apparatus, which adds a number of data values, has an adder and an asynchronous ripple counter. The adder adds each current data value to an adder sum of the preceding data values. The asynchronous ripple counter, which is coupled to the adder, generates a ripple count by counting occurrences of overflow of the adder. The accumulation apparatus outputs an accumulated data value having the adder sum as least significant part and the ripple count as most significant part.

    Abstract: A pulse width modulation controller (PWM) is disclosed which has a MOSFET (15) responsive to the error voltage (Verror) signal from the PWM amplifier (17) to detect a transient condition without delay ?Td. The MOSFET drain generates and applies a detection signal (S) to a delaying circuit (D). The delaying circuit (D) is responsive to the transient detection signal (S) to asynchronously output two latch signals (S1) and (S2) which on application to respective latch circuits (L1, L2) cause a change in conduction state of PMOS (8) and NMOS (9). This arrangement reduces voltage undershoot.
