Abstract: A collaborative operating system of audiovisual peripheral devices and an operating method thereof are provided. The system provides an audiovisual console, which includes an audiovisual processing unit, and a microcontroller, at least one connection interface, and a data-processing unit that implement a collaborative operation of the audiovisual peripheral devices. The audiovisual console connects with the peripheral device via the connection interface based on a communication protocol, and obtains a permission for accessing a camera and a microphone that are detected. The audiovisual console receives a video and an audio from the peripheral device based on the communication protocol. After the data-processing unit processes the video and the audio, the microcontroller generates and provides audiovisual data to the audiovisual processing unit. Accordingly, a display displays the video, and a speaker plays the audio, thereby allowing the audiovisual console that has no camera and microphone to hold a video conference.

Abstract: A memory device includes a resistor and a controller chip. The controller chip includes a first controller, a second controller, a first set of input/output (I/O) circuits, a second set of I/O circuits, a first calibration circuit, a second calibration circuit, and an arbitration circuit. The first controller transmits a first controller calibration request. The second controller transmits a second controller calibration request. The arbitration circuit instructs the first calibration circuit to perform a first controller calibration on the first set of I/O circuits using the resistor in response to the first controller calibration request, and instructs the second calibration circuit to perform a second controller calibration on the second set of I/O circuits using the resistor in response to the second controller calibration request. A first time interval of performing the first controller calibration and a second time interval of performing the second controller calibrations are non-overlapping.
