    Abstract: A processor according to embodiments comprises an on-board sample rate converter for converting a source audio signal that is sampled at a first sampling rate to an output audio signal that is sampled at a second sampling rate. The sample rate converter utilizes a master clock signal in converting the audio signal. The sample rate converter selects the master clock signal from available reference clock signals, such as an on-chip system clock or a bus interface clock, and scales the frequency of the selected clock signal to generate the master clock signal with the frequency of the second sampling rate.

    Abstract: A micro-coded sequencer controls complex conversion sequences independent of a central processing unit (CPU). Micro-coding provides for easily adding new process steps and/or updating existing process steps. Such a programmable sequencer in combination with an analog-to-digital conversion module such as an analog-to-digital converter (ADC) or a charge time measurement unit (CTMU), and digital processing circuits may be configured to work independently of the CPU in combination with the micro-coded sequencer. Thereby providing self-sufficient operation in low power modes when the CPU and other high power modules are in a low power sleep mode. Such a peripheral can execute data collection and processing thereof, then wake the CPU only when needed, thereby saving power. Furthermore, this peripheral does not require CPU processing so that time critical applications that do require control by the CPU can operate more efficiently and with less operating overhead burden.

    Abstract: A mixed signal device having an analog-to-digital converter (ADC) with offset and gain calibration using internal voltage references whereby the digital processor calibrates out offset and gain errors in the analog-to-digital converter by adjusting the analog input amplifier gain and offset or with software compensating the digital representations of the voltages measured. Two different known voltage values are used in determining the offset and gain adjustments needed to calibrate the ADC against the two know voltage values. The mixed signal device may further comprise a Bandgap voltage reference having an accurate known voltage value. Wherein the Bandgap voltage reference may be used for further offset and gain calibration of the ADC to produce substantially absolute voltage values.
