Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a process in which the information terminal performs a telephone service using the Internet.

2 is a block diagram showing an embodiment of an information terminal system using the Internet, which is a main part of the system, and the input / output control unit 11 digitally inputs an analog signal input by a microphone, a video camera, or the like mounted inside or outside the terminal. The data is converted into data and transmitted to the programmable circuit unit 14 through the data bus, and the data transmitted to the circuit unit 14 is restored and sent to an output device such as a wired or wireless earphone or a speaker (handset). In addition, the data is stored in a random access memory (RAM) of the memory unit 17 so that the central control unit 10 or other components can be accessed through modulation, demodulation, and compression processes.

The data input unit 12 may include a shortcut key for connecting a service provider using a phone number or the Internet input from a keypad or a touch screen, service mode setting (voice call and message, video call and message, short message, redial, auto answer, and a plurality of services). Simultaneous call, incoming call, etc.) and special key are mapped to ASCII code or Scan code and transmitted to the programmable circuit unit 14 and the central control unit 10 through the common bus. It performs the function. It also supports external keyboard input for scalability of data entry.

The serial or parallel port 13 may be connected to an interface of a computer or other system, such as various applications stored in the memory 17 or a real-time operating system. By uploading or downloading the information, it is possible to modify and edit the desired data. As a result, a system initial environment setting, a function for improving and updating a function of the terminal, and the like can be performed. An application program that performs these functions adopts a Graphic User Interface (GUI) method in consideration of the user's convenience, and can change environment settings and program functions through the screen.

The programmable circuit unit 14 partially handles the addressing decoder, data path assignment, data processing and processing, and control signal assignment, thereby loading a processor that is biased to the central controller 10. It reduces security and makes it secure so that it cannot be stolen by other systems. In addition, system logic can be easily improved and upgraded through software configuration. In other words, the programmable circuit unit 14 performs most of the functions except the arithmetic function of the central control unit 10.
