发明名称 System and method for scheduling access to an analog-to-digital converter and a microprocessor
摘要 An audio system is disclosed and includes a semiconductor device having an analog-to-digital converter (ADC) system and includes a controller and a programmable control register coupled to the controller. The ADC system also includes a plurality of channels coupled to the controller, each channel having an associated schedule bit within the programmable control register, an associated request bit within the programmable control register, and an associated interrupt request bit within the programmable control register. The ADC system also includes a scheduler coupled to the controller and to the programmable control register, the scheduler comprising logic to monitor a plurality of request bits to detect when any of the schedule request bits are set. Further, the semiconductor device includes a digital-to-analog converter (DAC) system coupled to the analog-to-digital converter system.
