摘要： A transmitter including a frequency synthesizer with a voltage-controlled oscillator that provides an oscillating signal, a programmable delay circuit that delays the oscillating signal to provide a delayed oscillating signal, a power amplifier that is configured to amplify the delayed oscillating signal for transmission sufficient to produce interference, and a delay controller that programs the delay circuit with a delay time that reduces interference caused by coupling from the power amplifier to the voltage-controlled oscillator. The delay circuit may be programmed to reduce control voltage change of the voltage-controlled oscillator as a function of delay change, and/or to reduce phase noise degradation at an output of the transmitter as a function of delay change. The delay may be adjusted based on detected operating temperature. A calibration value may be determined at a calibration frequency, in which a frequency offset may be determined based on a selected channel frequency.

摘要： A communication processor is operative to adapt the thread allocation to communications processes handled by a multi-thread processor on an instruction by instruction basis. A thread map register controls the allocation of each processor cycle to a particular thread, and the thread map register is reprogrammed as the network process loads for a plurality of communications processors such as WLAN, Bluetooth, Zigbee, or LTE have load requirements which increase or decrease. A thread management process may dynamically allocate processor cycles to each respective process during times of activity for each associated communications process.

摘要： In an embodiment, an apparatus includes: a sensor to sense real world information; a digitizer coupled to the sensor to digitize the real world information into digitized information; a signal processor coupled to the digitizer to process the digitized information into an image; a discriminator coupled to the signal processor to determine, based at least in part on the image, whether the real world information comprises an anomaly, where the discriminator is trained via a generative adversarial network; and a controller coupled to the discriminator.

摘要： A calibration current load is selectively coupled to an output of a pulse frequency modulated (PFM) DC-DC converter during a calibration operation to increase charge supplied from a battery supplying an input voltage to the converter. A voltage across a sense resistor in series with the battery is integrated during a measurement interval while the calibration current load is coupled to the output. A charge drawn per pulse from the battery is determined based on the sense resistor, the integrated voltage and the number of pulses during the measurement interval. Alternatively, a first PFM frequency is determined with a first calibration current load coupled to the converter output. A second PFM frequency is determined with a second calibration current load. The charge drawn per pulse from the battery is determined based on the first and second PFM frequencies and the first and second calibration current loads.

摘要： A system and method for presenting different GATT databases or different views of a GATT database based on the EATT bearer identity is disclosed. The GATT server identifies the EATT bearer being used and associates an application with that EATT bearer identity. The GATT server then creates an association between the application and a customized view of the GATT database that is presented to that application. In this way, a GATT client, with several applications resident thereon, may create a plurality of different connections to the GATT server, each with a unique EATT bearer identity. Each of these applications may have its unique customized view of the GATT database, based on that EATT bearer identity.

摘要： A dual resonant wideband meandered PCB antenna is disclosed. The antenna includes two meandered paths that are joined at a common feeding path. The meandered paths have different lengths, which results in different resonance frequencies. The antenna may also include a short circuit stub connected to the feeding path for impedance matching. In some embodiments, the antenna is formed on one layer of a printed circuit board. In another embodiment, to conserve space, the antenna may be formed on multiple layers of the printed circuit board.

摘要： Techniques for quickly and accurately determining whether a channel is being used for transmission of data using one of a plurality of communications protocols for low power signals using random data of a packet are disclosed. The techniques increase sensitivity and reduce the false alarm rate for a wide range of signal and noise levels. A noise detection technique uses an adaptive window size for fast noise detection that increases the rate of scanning channels during a signal identification period. In a BLE1M detection mode, detection of clusters of zero frequency deviation are used to reduce the false detection rate. Adaptive Zigbee symbol detection improves detection sensitivity beyond −97 dBm. The techniques use a chip-based differential to generate frequency deviation samples for Zigbee detection or data filtering frequency deviation samples generated using sample-based differentials based on an oversampled received signal to improve the signal-to-noise ratio.

摘要： A system and method for performing execute-in-place is disclosed, wherein the code is encrypted using AES-GCM and stored in an external memory device. The system includes only one cipher function that is used to encrypt the three counter values that are used to decrypted the encrypted code and to validate the Message Authentication Code (MAC). In some embodiments, the system precalculates a hash subkey so that generation of the Counter 0 value can begin as soon as a valid memory address is available. In addition, the cipher function is modified to utilized two or more cipher generation circuits and only one key expansion circuit. This improves the speed of the operation without a complete duplication of the cipher function hardware. In another embodiment, the cipher function is unrolled so that two or more rounds of key expansion and cipher generation are performed each clock cycle.
