  • Patent number: 10620916
    Abstract: A high level programming language provides a read-only communication operator that prevents a computational space from being written. An indexable type with a rank and element type defines the computational space. For an input indexable type, the read-only communication operator produces an output indexable type with the same rank and element type as the input indexable type but ensures that the output indexable type may not be written. The read-only communication operator ensures that any attempt to write to the output indexable type will be detected as an error at compile time.

  • Patent number: 10476455
    Abstract: A class-D amplifier system includes one or more pulse width modulation (PWM) output paths at least one of which includes one or more digital closed-loop PWM modulators (DCL-PWMM) in which at least one of the DCL_PWMM includes a digital integrator that provides an output value and receives a feedback value. The output value has an output resolution and the feedback value has a feedback resolution that is coarser than the output resolution. The output value is the sum of an integer multiple of the feedback resolution and a residue. Control logic decreases/increases the residue of the digital integrator toward an integer multiple of the feedback resolution over a plurality of clock cycles in response to a request to transition the class-D amplifier and forces an output of the DCL_PWMM to have an approximate 50% duty cycle after decreasing/increasing the residue over the plurality of clock cycles.

  • Patent number: 10123143
    Abstract: Errors in measurements of a resistor to monitor current through a speaker may be corrected to improve the accuracy, performance, or quality of other signals affected by the measurement. Error may occur in the current measurement resulting from variations in measurements involving the resistor, such as errors based on the sense resistor's response to temperature or voltage differential. Correcting the measurement errors can prevent the overcurrent condition from occurring, and otherwise improve audio output from the speaker. Thus, a method for correcting measurements in a speaker monitoring circuit may include monitoring a current through a speaker by receiving a measurement that is correlated to the current output through the speaker; and correcting the measurement for one or more inaccuracies in the measurement.
