摘要： Herein described are at least a system and a method of reducing or decreasing the rate of interrupts transmitted by a device to a microprocessor. In a representative embodiment, the device comprises a universal asynchronous receiver/transmitter. In a representative embodiment, the rate of interrupts is reduced by receiving and using a first signal as an input to a first counter. The first counter outputs a first count, and compares the first count to a value provided by a memory. Subsequently, a second signal is generated to initiate an interrupt when the first count equals the value. In a representative embodiment, a system for delaying transmission of an interrupt from a universal asynchronous receiver/transmitter (UART) to a microprocessor comprises a counter capable of generating a count, a memory capable of storing a value, and a comparator used for comparing the count to the value.

摘要： A method to perform DC compensation on a Radio Frequency (RF) burst transmitted between a servicing base station and a wireless terminal in a cellular wireless communication system that first receives the RF burst modulated according to either a first or second modulation format. Samples from the RF burst, taken from the training sequence, are produced and averaged to produce a DC offset estimate. The DC offset estimate is then subtracted from each of the samples. The modulation format of RF burst may then be identified from the samples. Depending on the identified modulation format, the DC offset estimate may be re-added to the samples when a particular modulation format is identified as the modulation format of the RF burst. This decision is made based on how well various components within the wireless terminal perform DC offset compensation.

摘要： A wireless receiver includes a local oscillator, a mixer, a band pass filter, a DC offset determination module, a DC offset correction module, a subtraction module, and a down converter. The local oscillator produces a local oscillation that a mixer uses to down convert the RF information signal to produce a Very Low Intermediate Frequency (VLIF) information signal at a VLIF and having a DC offset. The band pass filter band pass filters the VLIF information signal. The DC offset determination module produces a DC offset indication for the VLIF information signal. The DC offset correction module generates a DC offset correction based upon the DC offset indication. The subtraction module subtracts the DC offset correction from the VLIF information signal to substantially remove a DC offset of the post-filtered VLIF information signal. The down converter down converts the VLIF information signal to a baseband information signal. In an alternate embodiment, the VLIF information signal is down converted to baseband prior to removal of the DC offset component, which then resides at −VLIF frequency.

摘要： In a method and system for audio level detection and control, an amplitude of an audio signal may be compared to a threshold and an attenuation applied to the audio signal may be adjusted based on the comparison. In instances that the amplitude of the audio signal is greater than or equal to the threshold the adjustment may comprise increasing a first attenuation factor until the amplitude of the audio signal is less than the threshold. The first attenuation factor may be subsequently decreased until the amplitude of the audio signal is greater than or equal to the threshold or until the first attenuation factor is equal to zero. The attenuation of the audio signal may be controlled via a digital gain circuit within the hardware audio CODEC, wherein an overall attenuation factor of the digital gain circuit is a sum of the first attenuation factor and a second attenuation factor.

摘要： Embodiments for processing media over Internet Protocol (IP) packets in a wireless device are provided. Embodiments enable downlink and uplink media over IP flows within the wireless device that reduce the load on the application processor (AP) of the wireless device. In an embodiment, media over IP flows bypass the AP entirely allowing the AP to enter a power saving mode during media over IP sessions. This results in increased battery lifetime and reduced power consumption of the wireless device. In addition, the media over IP session quality is improved by the reduced latency resulting from bypassing the AP.

摘要： A central audio hub, comprising an audio switch, a bus matrix, and an audio buffer, is triggered to read audio samples of an audio stream from the audio buffer. The central audio hub routes the audio samples via the bus matrix to one or more surrounding audio modules such as an audio codec and an audio interface communicatively coupled to the central audio hub. The audio stream may be directly from an external application processor or from an external DDR. With the audio stream from the DDR, a DMA controller may fetch the audio samples from the DDR in response to a request received from the audio buffer, and store the fetched audio samples into the audio buffer for routing. The audio switch may be triggered at a determined sampling rate to read the audio samples from the audio buffer utilizing a determined sample format, and to route the audio samples to the surrounding audio modules.
