Abstract: An integrated circuit for controlling a slave device is provided. The integrated circuit includes a pin, a micro-controller and an inter integrated circuit (I2C) bus controller coupled between the micro-controller and the pin. The I2C bus controller includes a transceiver unit coupled to the slave device via the pin, and an interface unit coupled between the transceiver unit and the micro-controller. The interface unit includes a start control register and a stop control register. The start control register provides a start signal to the slave device via the transceiver unit when the start control register is programmed by the micro-controller. The stop control register provides a stop signal to the slave device via the transceiver unit when the stop control register is programmed by the micro-controller. The micro-controller programs the stop control register according to an interrupt signal from the interface unit.

Abstract: The invention discloses a computer system having voice-control function. The computer system includes a voice-recognition module, a shared memory, a microcontroller, a power-management module and a central processing unit. The voice-recognition module receives an external voice signal via a microphone and determines whether the external voice signal corresponds to an operation instruction. The shared memory is used for storing shared state information. The microcontroller is used for setting the shared state information according to the operation instruction when the external voice signal corresponds to the operation instruction. The power-management module generates a power-management signal according to the shared state information in the shared memory. When the power-management module transmits the power-management signal, the central processing unit executes a processing operation corresponding to the operation instruction according to the shared state information in the shared memory.
