Abstract: An adaptive multi-model item selection method, comprising: receiving, from one of a plurality of client devices, a request including a client-side feature vector representing a state of the client device; determining, by an advocate model, a probability distribution of a plurality of specialist cluster models from the client-side feature vector; choosing, by a use case selector, a cluster corresponding to a use case from the probability distribution; and obtaining, by the use case selector based on the cluster (i.e., the cluster that was sampled by the user case selector), a specialist cluster model from the plurality of specialist cluster models.

Abstract: An apparatus includes a plurality of delay elements, a plurality of multipliers and an accumulator to form a biquad stage; and a precision logic circuit. The biquad stage includes feedback paths; at least one feedback path has an adjustable bit precision; and the precision logic is adapted to regulate the bit precision of the feedback path(s) based at least in part on at least one parameter that is associated with the biquad stage.

Abstract: A wireless communication device is disclosed that reduces undesired audio underflow in a digital to analog receive path that employs time domain isolation. In one embodiment, one or more buffers in the receive path receive processed audio samples from a signal processor. A control circuit senses when the buffers in the receive path are substantially empty. In response to a substantially empty determination by the control circuit of one embodiment, the control circuit instructs one of the buffers to repeat the last processed audio sample which that buffer received to reduce or avoid audio underflow.

Abstract: A technique that includes providing a buffer to receive data from a processor of a wireless device in response to an active mode of the processor and selectively coupling an input terminal of a filter to the buffer based on a status of the buffer.

Abstract: In one embodiment, the present invention includes a method for determining a level of a buffer that stores data samples. The level may be determined at a predetermined position of a data frame sequence. Based on the level of the buffer at this position, a vocoder and modem of a mobile station may be synchronized. One or both of the vocoder and modem may be adjusted to attain the synchronization. Thus a rate mismatch between the vocoder and modem may be resolved.

Abstract: In one embodiment, the present invention includes an apparatus for permitting diagnostic testing of a wireless device. The apparatus may include a first switch to route diagnostic information or acoustic information received from a processor of the device, a codec coupled to the first switch to code the routed diagnostic information or acoustic information, and a second switch coupled to the codec to route the coded diagnostic information to a first port of the wireless device and to route the coded acoustic information to the first port or a second port of the wireless device.
