The byte code loader 45 extracts the coordinate data and the control program included in the byte code file, and stores the coordinate data in the coordinate data memory 46.
And the control program is stored in the control program memory 47.

By storing the coordinate data and the control program relating to the application program in the coordinate data memory 46 and the control program memory 47 in this manner, the preparation for executing the application program is completed.

When the preparation for executing the application is completed, the portable information terminal 20 executes the application previously generated by the personal computer 10 in accordance with the predetermined operation on the portable information terminal 20. Also, when an event occurs with the touch pen 20d by the user of the portable information terminal 20 during the execution of the application on the portable information terminal 20, the event recognition unit 48 of the interpreter 24 transmits coordinate data and message information related to the event. The message information is transmitted to the message transmission unit 50 and the coordinate data is transmitted to the component address search unit 49.

Upon receiving the coordinate data relating to this event, the part address search unit 49 searches the part address information of the drawing command product corresponding to the coordinate data via the coordinate data memory 46 and the part address memory 41. The component address information is transmitted to the message transmission unit 50.

The message transmitting unit 50 transmits the message information and the component address information relating to the event to the message receiving unit 33 of the component control 23 together.

When the message receiving unit 33 receives the message information and the component address information relating to these events, it transmits the component address information to the component command searching unit 34.

The component command search unit 34 searches for a drawing command component and a component control program corresponding to the component address information, and transmits the component control program and message information to the component command control unit 35 corresponding to the drawing command component. I do.

The component command control unit 35 executes a control operation relating to message information based on the component control program.

After executing the control operation relating to the message information based on the component control program, the component command control unit 35 further includes the control program relating to the application program, that is, the interpreter 24 in the message information. When it is determined that the control program to be executed remains, the control address information corresponding to the control program is searched from the component-side control address memory 32 by the component command search unit 34, and the control address information is searched by the control program of the interpreter 24. It is transmitted to the unit 51.

The control program search section 51 searches for a control program corresponding to the control address information in cooperation with the control address memory 42 and the control program memory 47, and sends the searched control program to the virtual machine generation section 53. Transmit.

The virtual machine generator 53 generates a virtual machine 52 based on the control program, and causes the virtual machine 52 to execute a control operation based on the control program. Thus, the application can be executed on the portable information terminal 20.

In the portable information terminal 20, there are two kinds of preparation operations, application preparation for initial application startup and application execution preparation for normal application startup.

The interpreter 24 of the portable information terminal 20
When detecting an instruction for selectively starting an application corresponding to the bytecode file stored in the bytecode file memory 43, the CPU determines whether or not it is an initial startup or a normal startup. Based on this determination result, FIG.
The application execution preparation processing shown in (b) is performed. Note that the initial start of the application program corresponds to a case where the application program stored in the bytecode file memory 43 is started for each application program for the first time. Not say.
