    摘要: An electronic device includes a far-field voice (FFV) processor including a source selection module. The source selection module receives a set of audio signals and determines, for each audio stream, whether the audio stream is relevant to an application. The source selection module receives several separate probability computations, with each probability computation providing a probability of the presence of a particular characteristic. Additionally, the source selection module receives one or more applications as well relevance information (e.g., one or relevant characteristics) associated with the one or applications. The source selection module can used respective probabilities to determine if one or more characteristics are present in an audio signal, and compare the characteristic(s) to the relevance information for the application. Using this information, the source selection module can determine, for each audio signal, to which respective application the audio stream is relevant.

    摘要: A PCIe retimer includes read-only vendor registers with low latency mode entry and exit values. In-band low latency switching logic monitors the output of an elastic buffer for read commands of the vendor registers and, when such read commands are received, reads the corresponding address and switches a multiplexer between a link training data path and a low latency data path based on the return value of the read operation. Read commands, and therefore control of data path switching, is handled entirely in-band. Return values of the read operations indicate success or failure of mode switching to the root complex.

    摘要: Described herein are systems and methods related to a converter including a first input, a second input, and a number of digital to analog converter (DAC) cells. A DAC cell includes a first circuit, a first leg associated with a first output of the DAC cell, and a second leg associated with a second output of the DAC cell. The first circuit is configured to provide a return to zero operation. The DAC cell is configured to provide a data magnitude at a polarity on at least one of the first leg or the second leg during at least a portion of the clock cycle. The data magnitude and the polarity being provided in accordance with a first signal at the first input and a second signal at the second input.
