    摘要: The programmable analog input/output integrated circuit system includes a plurality of integrated circuit pins, an analog input/output circuit, a control module, and a switching module. The analog input/output circuit is coupled to the plurality of pins and determines the input/output status of each of the pins. The control module generates an I/O control signal and a switching control signal based on the input/output status of the integrated circuit pins. The I/O control signal is provided to the analog I/O circuit, which configures itself as an input or output based on the I/O control signal. The control module provides the switching control signal to the switching module, which configures itself to couple the analog input and/or analog output to corresponding functional circuitry of the corresponding integrated circuit.

    摘要: A audio codec includes a first analog to digital converter for producing a first one-bit data stream, a second one-bit data stream is received from a digital microphone. A selection module produces a one-bit output signal that is the first one-bit data stream when a selection signal is in a first state, and produces a the one-bit output signal that is the second one-bit data stream when the selection signal is in a second state. A decimation and filter module produces a down sampled signal based on the one-bit output signal.

    摘要: A method and apparatus for processing content data includes processing that begins by receiving modulated data via a channel that couples a content display device to a content processing device. The processing continues by introducing the content data onto the channel and separating the modulated data from the content data. The processing then continues by retrieving data from the modulated data, wherein the content display device modulates the modulated data. The processing continues by processing the data to produce presentation information. The processing then continues by processing the content data for presentation on the external content display device based on the presentation information.

    摘要: A digital microphone interface includes a phase generator for generating a phase signal. A clock generator produces a digital microphone clock at a selected frequency based on the frequency select signal, and supplying the digital microphone clock to a digital microphone. A first data latch, operably coupled to the phase generator, produces a stream of first data from a first channel of the digital microphone, based on a phase select signal and the phase signal.
