2. Description of the Related Art A conventional mobile telephone is equipped with one control means called a CPU, and this one CPU performs both communication processing and application processing.

However, the display means (LC
Due to the diversification of applications installed in mobile phones such as D) of large size and color, and playback of still images and moving images of cameras etc., the processing load becomes too heavy with only one conventional CPU. There was a risk that the processing would not be in time. Therefore, the mobile phone is provided with two control means (CPU), and C for performing processing for communication is provided.
The role is shared between the PU and the CPU dedicated to the application for processing multimedia data such as images,
A method of distributing the processing load on the CPU has been considered.
In the mobile phone having the two CPUs, the application process handles more display data than the communication process, so that the LCD is connected to the data bus of the application CPU.

However, the display contents different from the display for the application may be updated by an instruction from the communication CPU. For example, the display of an antenna pictogram indicating the reception sensitivity and the display of the remaining battery level are that.

When the LCD is connected to the data bus of the application CPU, once the communication CPU updates the display contents, the application CPU once
Information for updating, the application CPU analyzes the data sent from the communication CPU, converts the data into display updating data, and then outputs the data to the LCD.

However, according to the above-mentioned method, the application CPU which is processing an extremely heavy-duty application, further receives the update information of the display content sent from the communication CPU, analyzes it, and then displays it. Since it is converted to update data and output to the LCD,
There is a problem that the processing load on the application CPU becomes heavier.

Further, since the display is once performed via the application CPU, there is a problem that the time required for updating the display becomes long.

It is output to the display means 3 via S4 (S17) and displayed on the non-application data display means 32 of the display means 3 (S18).

In the above description, when the application data D1A is output from the first control means 1 to the second control means 2, it is limited to the output to the internal circuit 22, but the internal circuit 22 has the CPU section 21. The application data D1A sent from the first control means 1 via the is processed in real time and displayed on the display means 3.

[0065]

As described above, in the portable terminal device 100 of the present invention, which has two control means each equipped with a CPU, the application control means (second control means) 2 equipped with an application CPU is provided.
Data selection means (24 and 23 or 25) is provided in the application CPU unit 21 of the application control unit 2 to output the data output from the communication control unit (first control unit) 1 having the communication CPU. Display means 3 after sending and processing application data
Output to the display unit 3 without passing through the application CPU unit 21. When the display updating data output from the communication control means is displayed on the display means 3 by configuring the selecting means by hardware, the application control means 2
Since data can be selected without the intervention of software in the CPU section 21, the application CPU section 21
It is possible to display on the display means 3 without going through. Therefore, even when the display contents are updated on one display means 3 from the two control means, even when the display is updated from the communication control means 1, without going through the CPU section 21 of the application control means 2. Since the display data can be directly output from the communication control means 1 to the display means 3, there is an effect that the processing load of the CPU section 21 of the application control means 2 can be reduced.
