ABSTRACT:
An apparatus and method for controlling an operation of a portable terminal having a multimedia function are provided. The apparatus includes a multimedia processor for performing the multimedia function when a controller is in a sleep mode wherein the controller is converted to an active mode when a specified key signal is input into the controller in the sleep mode and outputs an inactive signal to inactivate the multimedia processor. According to the present invention, the portable terminal having the controller controlling the mobile communication function and the multimedia processor controlling the multimedia function, can independently perform the mobile communication function and the multimedia function according to the specified key input. Furthermore, according to the present invention, the controller which controls the mobile communication function need not control the multimedia processor which controls the multimedia function. Hence, it is possible to reduce power consumption and software errors occurring when the controller controls the multimedia processor.
