Abstract:
PURPOSE: A virtual system and an instruction executing method thereof are provided to analyze the execution of an application program or an operating program in real time. CONSTITUTION: A VMM(Virtual Machine Monitor)(120) virtualizes a hardware(110). A user domain(140) is operated by a virtualized hardware. A root domain(130) is operated by the virtualized hardware. The root domain manages the user domain. The virtual machine monitor analyzes the execution operation of the user domain in real time. The virtual machine monitor stores the analyzed execution information to the root domain.
Abstract:
A wireless communication method for exchanging wireless devices after a confirmation procedure of a user and an AV device to which the same is applied are provided to prevent a currently connected wireless device from abruptly being disconnected while a user does not recognize the disconnection. A wireless communication method for exchanging wireless devices after a confirmation procedure of a user comprises the following several steps. If it is necessary to set up a wireless connection to a new wireless device, a controller checks whether a wireless device exists which is currently connected via a bluetooth communication module(S320). If the connected wireless device exists in the step S320(S330), the controller controls a display information generator for displaying a GUI for asking a query if the currently connected wireless device gets disconnected(S340). If the user selects disconnection via the displayed GUI(S350), the controller disconnects the wireless device currently connected via the bluetooth communication module(S360). The controller sets up a wireless connection of a new wireless device via the bluetooth communication module(S370). If the user selects maintenance of a connection, the controller maintains the wireless connection of the wireless device(S380). Even though the connected wireless device does not exist, the controller generate a signal for maintaining the wireless connection of the wireless device.
