Description

A virtual simulation system and a hardware control program embodiment method using the same}

The present invention relates to a virtual simulation system and a method for implementing a hardware control program, and in particular, includes hardware modules and corresponding software modules constituting an embedded system used for a practical training, and graphically displays an execution result according to an execution program code. The present invention relates to a virtual simulation system and a hardware control program implementation method.

An embedded system is a system having a plurality of hardware modules and a microprocessor for performing a specific purpose in one system. The embedded system is an independent system in which the microprocessor displays execution results according to an input program through the hardware modules. Says the system. In teaching the operation principle of the embedded system, it is very important for the trainees to directly deal with the hardware platform, which is a kind of training equipment.

The hardware platform is generally a kind of system board composed of a microprocessor and a plurality of hardware modules such as LCD, LED, FND (7 Segment LED), Dot Matrix, Stepping Motor, Key Pad, etc. Is executed. As a result, the trainees learn the operation state of the hardware modules according to the program they have written, and if there is an error, they understand the operation principle through the process of correcting and supplementing the program.

On the other hand, the operation principle of such an embedded system is not simple, even if a lot of practice time is organized, there is a problem that the sufficient understanding of the operation principle of the embedded system can not be achieved only with the assigned practice time. Therefore, the education facilitator conducting the practical education, endeavors to enhance the effect of the practical education by assigning practical tasks to the trainees to supplement the contents of the previous time or to increase the application ability.

However, there is a problem in that when the presenter assigns a task, the content that has been carried out in the practice time cannot be assigned as the task as it is. The reason is that the contents of the training are related to writing a program required to control the hardware platform. However, since the hardware platform required for this purpose is expensive, it is difficult to equip the training platform. As a result, a training coordinator cannot assign a task of directly controlling a hardware platform, and there is a problem of only giving a principle or conceptual task.

The technical problem to be solved by the present invention is a virtual simulation system that allows the trainee to experience and verify the operation principle according to the practice task using a simulator that provides the same graphic environment as the hardware equipment that is handled in the actual practice place at home and The present invention provides a method for implementing a hardware control program.

Hardware control program implementation method according to an embodiment of the present invention for solving the technical problem,

Patching and decoding each command included in an embedded system control program written by a user, determining whether the decoded command includes information for controlling a specific hardware module constituting the embedded system, and determining Converting information controlling the specific hardware module into information controlling the specific software module corresponding to the result, executing the specific software module according to the converted information, and output data of the specific software module Displaying through a graphical user interface

Advantageously, the method of implementing a hardware control program further includes displaying corresponding result data through said graphical user interface when a specific event occurs through said graphical user interface.

The virtual simulation system according to an embodiment of the present invention for solving the technical problem,

A control module that sequentially patches and decodes each instruction included in the input hardware control program, and converts each hardware module control information included in the decoded instructions into software module control information; A first program processing module for executing an internal program having the same function as each hardware module and generating result data according to the converted control information, and executing a user graphic interface code to build a graphic environment, and executing the first program processing And a graphical user interface for changing the graphical environment corresponding to the result data output from the module.

Preferably, when a specific event occurs through the graphical user interface, an internal program having the same function as each hardware module is executed according to the control information input from the graphical user interface to generate result data. And a second program processing module for outputting result data to the graphical user interface.

The virtual simulation system and the method for implementing the hardware control program according to the present invention can give the trainees the task of writing the same program as the program capable of controlling the hardware platform, thereby improving the quality of the practice training. There are advantages that can be achieved. In addition, since the steps of using the virtual simulation system and the steps of using the actual hardware platform are the same, there is an effect that allows the user to have a feeling of directly controlling the hardware.

A program for operating the hardware modules included in the hardware platform is generated and compiled 110. The program may be a program assigned to a task by a training educator, and is the same as a program actually written in the training. The virtual simulation system according to the present invention is executed to establish a graphic user interface environment of the same type as the hardware platform (120). Here, the graphical user interface environment is connected with a plurality of software modules.

Using the virtual simulation system, each instruction included in the compiled program is sequentially patched and decoded (130). Each instruction may include instructions for controlling each hardware module. It is determined whether the decoded command includes control information for controlling a specific hardware module (140). For example, it is determined whether control information for displaying specific data is included in the LCD block or the LED block.

When control information about a specific hardware module is included, the control information is converted into information suitable for a software module corresponding to the hardware module and output (150). The converted control information drives the corresponding software module, and the software module generates and outputs the result data accordingly. The result data is received and the graphic user environment is changed and displayed (160). Here, each software module performs the same operation as the corresponding hardware module.

The address of the software module and the control information are stored (170). This is to continuously display the programmed data on the screen until the end event occurs. It is determined whether all instructions included in the compiled program have been processed (180). If not done, patch and decode the next instruction. When all is completed, it is determined whether a separate new event has occurred through the graphical user interface (190). If so, take the appropriate action.
