A method and apparatus for mitigating electromagnetic noise in an electronic device. The method includes generating a trigger clock signal at a first frequency, and generating a second clock signal at a second frequency. The second frequency is higher than the first frequency. The method also includes receiving an input signal with a converter circuit, detecting an event based on the trigger clock signal, and predicting a time for a conversion of the input signal based on the detected event. The method further includes blanking the second clock signal for a predetermined period based on the predicted time for a conversion.

Systems and methods for mitigating noise in an electronic device

A real-time reconfigurable input/output interface of a controller and a method of reconfiguring the same. The reconfigurable interface enables the controller to communicate with a plurality of peripheral digital subsystem blocks, and includes an input/output interface, a profile memory, and a state machine. The input/output interface includes a plurality of data lines including a shared portion that are shared among the plurality of peripheral digital subsystem blocks. The profile memory stores a plurality of interface profiles, each interface profile defining a configuration of the input/output interface to communicate with an associated one of the peripheral blocks. The state machine is coupled to the profile memory to receive interface profiles and to the input/output interface. In response to each request to communicate with a particular peripheral block, the state machine configures the input/output interface according to the interface profile associated with the particular peripheral block.

The method includes receiving an encoded audio file at the electronic device. Further, the method includes selectively decoding () the encoded audio file, in correspondence with a spectral response of the audio output device, to provide decoded audio data. Furthermore, the method includes playing () the decoded audio data over the audio output device.

Method and system for selectively decoding audio files in an electronic device

A device for verifying hardware in a circuit arrangement that includes one or more configuration elements () operable to configure hardware elements () that are electrically coupled by one or more electrically-conductive pathways (). The device includes a hardware-verification register () coupled to at least one of the electrically-conductive pathways (). The register () is operable to sample a voltage level on at least one of the electrically-conductive pathways () at a first time point; store in a memory one or more bits, each bit representing the voltage level on at least one of the electrically-conductive pathways () at the first time point; sample a voltage level on at least one of the electrically-conductive pathways () at a second time point; and compare, for at least one of the electrically-conductive pathways, the voltage level at the first time point and the voltage level at the second time point.

Device and method for detecting corruption of digital hardware configuration

A sigma-delta DAC circuit includes a sigma-delta modulator for producing and outputting an n-bit digital signal representative of an input analog signal, wherein n is a positive integer greater than 1, and is preferably equal to 4, 5 or 6. A differential n-bit DAC is for converting a 2 -bit digital signal and a 2 -bit inverted digital signal processed and output by a bit shifter and a differential decoder to a differential analog signal. The sigma-delta modulator has a movable zero for enabling dynamic spectral shaping of the differential analog signal.
