  • Patent number: 7564842
    Abstract: The disclosure is a routing method for data in a personal area network. The personal area network includes a plurality of nodes. The method includes receiving a frame at a node, determining whether the node contains a routing table entry for the frame destination, and when the node contains a routing table entry, determining a route for the frame based on a first routing protocol. The method further includes, when the node does not contain a routing table entry for the frame destination, determining whether a route should be discovered for the frame destination, and when a route should not be discovered, determining a route for the frame based on a second routing protocol.

  • Patent number: 7565128
    Abstract: A signal processing circuit is proposed, which is intended to receive a pair of input signals Sp and Sn in phase opposition on two input terminals and to provide two pairs of output currents SIp and SIn in phase opposition on four output terminals. Each input signal Sp and Sn is amplified in an amplification unit LNAUp and LNAUn and subsequently split in a splitting unit SPLUp and SPLUn. The invention is such that each of the two splitting units SPLUp and SPLUn includes at least two branches, respectively BIp, BQp and BIn, BQn connected between said amplification unit, respectively LNAUp and LNAUn, and one of said output terminals, the four branches BIp, BQp and BIn and BQn each including at least an impedance, respectively RIp, RQp, RIn, RQn, having identical characteristics. Mixer circuits can be easily stacked with this signal processing circuit.

  • Patent number: 7565591
    Abstract: Consistent with an example embodiment, the amount of time required for testing circuits that contain a plurality of different clock domains is reduced. According to the embodiment, during selection of the input test pattern to test logic circuits between a timing sensitive flip-flop in a first clock domain that captures a response that depends on test data in a source flip-flop in a second, different clock domain, account is taken of whether the data in the first flip-flop will change value if it is clocked when the response is captured. If not, it may be assumed that uncertainty about the timing relationship of different clock domains does not introduce uncertainty with respect to the data from the timing sensitive flip-flop, so that the response data at the second flip-flop can be treated as reliable.

  • Patent number: 7565563
    Abstract: This invention relates to multiprocessor arrangements with shared non-volatile memory and the design of the access control of this memory, in particular to such memories embedded or integrated into circuits (ICs) as used in mobile phones, PDAs or laptop computers. To reduce power consumption, the processor clock rates are often varied depending on the current performance requirements. Differing clock rates of processors sharing a non-volatile memory leads to relatively long read access times of the latter, since the particular microprocessor fetching the data from the memory is usually halted until the data are available. When dual or multi-port non-volatile memory and multiple asynchronous clocks are used, access times are even longer since clock synchronization between the ports is necessary. The present invention overcomes this problem by providing a plurality of wait timers, preferably one dedicated to each processor, advantageously each being clocked synchronously with its associated processor.

  • Publication number: 20090179682
    Abstract: The present invention relates to emphasizing and de-emphasizing of an analog data signal. Using a main analog driver (14) a data signal indicative of bit values of binary data is converted into a first analog data signal. A second data signal is determined by delaying the data signal a predetermined time interval and inverting the delayed data signal. Using a de-emphasis driver (114), the second data signal are converted into a second analog data signal, wherein the second analog data signal is additive to the first analog data signal if the data signal and the second data signal are indicative of a same bit value, and wherein the second analog data signal is subtractive to the first analog data signal if the data signal and the second data signal are indicative of an opposite bit value. The first analog data signal is emphasized or de-emphasized by superposing the first analog data signal and the second analog data signal.
