Description

  The present invention relates to an engine usage management method and a mobile communication terminal device. More specifically, the present invention relates to a reproduction process of a content object that is mounted on a mobile communication terminal device and stored in a content file by an application, and a rendering process by the application. The present invention relates to an engine usage management method that can be used for a mobile communication terminal and a mobile communication terminal device that uses the method.

  2. Description of the Related Art Conventionally, mobile communication terminal devices represented by mobile phone devices have been widely used. Advances in technology relating to such mobile communication terminal devices are remarkable, and mobile communication terminal devices having various functions such as not only calling and mail functions but also downloading games and using them as game machines have been put into practical use. Such game functions can also be realized by high-quality images and three-dimensional sound due to recent advances in information processing technology, downsizing of information processing devices due to advances in high integration technology, and recent advances in information processing technology. It has become a highly functional one that can handle voices.

In order to perform high-level drawing processing and audio reproduction processing as described above at high speed, the mobile communication terminal device performs content processing such as drawing processing and 3D sound stored in a content file in addition to the central processing unit (CPU). An engine that can be used for the reproduction process is mounted (see Patent Document 1). By using such an engine, it is possible to perform high-speed processing while reducing the processing load of the central processing unit during drawing processing and reproduction processing (hereinafter referred to as “conventional example”).
JP 2006-157743 A

  In the above-described conventional example, the engine is used for the reproduction process and the drawing process. However, when the reproduction process and the drawing process compete, generally, the engine cannot be used only for one of the processes. For this reason, a designer of a game application or the like has been required to make a design that does not cause competition between the reproduction process and the drawing process. Such a request has been a major limitation from the viewpoint of providing an interesting game for the user and from the viewpoint of the degree of freedom in game design.

  By the way, the content object is provided in a compressed state, and it is generally necessary to perform a decompression process in order to reproduce it. This expansion process is performed according to a standard algorithm, and can also be performed by a central processing unit (hereinafter also referred to as “CPU”) that executes various programs by executing the expansion process program. However, since 3D sound data and moving image data have a huge amount of data to be processed, it is not practical to perform expansion processing by executing a normal program.

  On the other hand, the drawing process accompanying the execution of the application can also be performed by normal program execution without using the engine. In addition, the amount of data to be processed by the application during the execution is much smaller than that of the content object development process. However, when drawing processing is performed by normal program execution, the CPU load increases and the processing is slower than when the engine is used.

  In addition, even for applications that require playback processing and rendering processing, depending on the type of playback processing, rendering processing, and application, the frequency of contention between playback processing and rendering processing during application execution, playback processing, and rendering There are various needs for simultaneous execution with processing.

  The present invention has been made in view of the above circumstances, and an engine usage management method and a mobile communication terminal capable of optimizing the use of an engine when executing an application involving a reproduction process and a rendering process of a content object An object is to provide an apparatus.

  From a first viewpoint, the present invention can be used for a reproduction process by an application of a content object mounted in a mobile communication terminal device and stored in a content file, and a drawing process by the application, and at the same time, the reproduction In an engine usage management method that cannot be used for both the processing and the rendering process, the engine is used for the playback process regardless of whether or not there is a conflict with the rendering process, and the competition with the playback process. An engine use management method characterized by restricting use of the engine for the drawing process based on a relationship.

  In this engine usage management method, the engine is used for the reproduction process regardless of whether or not there is a conflict with the drawing process. For this reason, an engine is always used for the reproduction processing of content objects such as 3D sound data and moving image data in which the amount of data to be processed is enormous.

  On the other hand, the use of the engine for the rendering process is limited based on the competitive relationship with the reproduction process. In other words, when there is a conflict with the playback process, or when there is a possibility of a conflict with the playback process, the rendering process requires a smaller amount of data than the playback process. Use of the engine is limited. Such restrictions include not using any engine for drawing processing.

  Therefore, according to the engine usage management method of the present invention, it is possible to optimize the usage of the engine when executing an application involving the reproduction processing and rendering processing of the content object.

  In the engine usage management method of the present invention, the rendering process is performed for the rendering process by executing the rendering process using a normal processing resource without using the engine over the entire period of execution of the application. It is possible to limit the use of the engine. Here, “normal processing resource” refers to a resource used for normal program execution in the CPU. In this specification, the term “normal processing resource” is used in this sense.

  In this case, the drawing process is executed using the normal processing resource without using the engine over the entire period of execution of the application. For this reason, there is no competition regarding the use of the engine between the reproduction process and the drawing process. The engine use restriction for such drawing processing is suitable when a content object reproduction process is often executed and an application that only needs to perform a relatively simple drawing process such as a two-dimensional drawing process during the reproduction process is executed. ing.

  Further, in the engine usage management method of the present invention, the rendering process is performed by using the normal processing resource without using the engine when competing with the reproduction process. Therefore, the use of the engine can be restricted. In this case, when competing with the reproduction process, the drawing process is executed using the normal processing resource without using the engine. For this reason, it is possible to use the engine for the drawing process when the engine is not used for the reproduction process while giving priority to the use of the engine regarding the reproduction process. Therefore, engine utilization can be optimized.

  In the engine use management method of the present invention, the engine is used for the rendering process by temporarily suspending the application during a period in which the engine is used for the playback process. Can be limited. In this case, the application is temporarily stopped during the period when the engine is used for the reproduction process. For this reason, there is no competition regarding the use of the engine between the reproduction process and the drawing process. Such engine use restriction for the rendering process is suitable when an application that does not necessarily require the rendering process is executed during the playback process period.

  From the second point of view, the present invention can be used for the reproduction process by the application of the content object stored in the content file and the drawing process by the application. At the same time, both the reproduction process and the drawing process can be used. Engine means that cannot be used for the purpose of the drawing process, and the engine is used for the reproduction process regardless of whether or not there is a competition with the drawing process. An engine use managing means for restricting use of the engine.

  In this mobile communication terminal apparatus, the engine use management means causes the engine to be used for the reproduction process regardless of whether or not there is a conflict with the drawing process. For this reason, an engine is always used for the reproduction processing of content objects such as 3D sound data and moving image data in which the amount of data to be processed is enormous. On the other hand, the engine use management means restricts the use of the engine for the drawing process based on the competitive relationship with the reproduction process.

  That is, the mobile communication terminal device of the present invention can execute an application using the above-described engine usage management method of the present invention. Therefore, according to the mobile communication terminal device of the present invention, it is possible to optimize the use of the engine when executing an application involving a content object reproduction process and a drawing process.

  In the mobile communication terminal device of the present invention, the engine means can be a hardware resource.

  Further, in the mobile communication terminal device of the present invention, when the drawing engine use prohibition is set at a predetermined position in the application, the drawing processing corresponding to the drawing processing request from the application is distributed to the normal processing resources. The drawing process distribution control means may be the engine use management means. In this case, the drawing process distribution control unit distributes the drawing process to the normal processing resources over the entire period of execution of the application. For this reason, there is no competition regarding the use of the engine between the reproduction process and the drawing process. The engine use restriction for such drawing processing is suitable when a content object reproduction process is often executed and an application that only needs to perform a relatively simple drawing process such as a two-dimensional drawing process during the reproduction process is executed. ing.

  Further, in the mobile communication terminal device of the present invention, a drawing that is mounted on the application and that executes the drawing processing using normal calculation processing resources without using the engine when competing with the reproduction processing. The process control means can be the engine use management means. In this case, when competing with the reproduction processing, the drawing processing control means performs control to execute the drawing processing using the normal arithmetic processing resources without using the engine. For this reason, it is possible to use the engine for the drawing process when the engine is not used for the reproduction process while giving priority to the use of the engine regarding the reproduction process. Therefore, engine utilization can be optimized.

  In the mobile communication terminal of the present invention, the engine use management means may be a pause control means for temporarily stopping the application during a period in which the engine is used for the reproduction process. In this case, the pause control means pauses the application during the period when the engine is used for the reproduction process. For this reason, there is no competition regarding the use of the engine between the reproduction process and the drawing process. Such engine use restriction for the rendering process is suitable when an application that does not necessarily require the rendering process is executed during the playback process period.

  As described above, according to the engine usage management method of the present invention, it is possible to optimize the use of the engine when the mobile communication terminal device executes an application involving the reproduction process and the rendering process of the content object. There is an effect.

  Further, according to the mobile communication terminal device of the present invention, there is an effect that the use of the engine can be optimized when executing the application accompanied by the reproduction process and the rendering process of the content object.

When the drawing process performed by the program 32A _j is performed, it is specified to use only a later-described normal arithmetic processing resource (a later-described general-purpose central processing unit) included in the control unit 21. On the other hand, when the engine use flag 35 _j is OFF, it is indicated that the use of the engine unit 25 by the content file development process does not conflict with the drawing process performed by the application program 32A _j . Therefore, when the engine use flag 35 _j is OFF, the engine unit 25 is used for both the content file development process and the drawing process by the application program 32A _j .

That is, the usage management method of the engine unit 25 in the processing of various content files is specified by the value of the engine usage flag 35 _j . The value of the engine use flag 35 _j is referred to by the control unit 21 when the application programs 32A ₁ , 32A ₂ ,.

According to the value of the engine usage flag 35 _j .

  The engine unit 25 is a hardware resource that can be used for rendering processing and content object playback processing associated with application execution in accordance with instructions from the basic processing program 31A. Rendering processing and content file development are performed more than normal processing resources. Processing (that is, content object reproduction processing) can be performed at high speed. By using the engine unit 25, a drawing process and a content object reproduction process associated with the execution of the application are performed.

<Operation>
Next, a description will be given mainly focusing on the usage management method of the engine unit 25 in the mobile phone device 10A configured as described above. It is assumed that the basic processing program 31A and the application program 32A ₁ are stored in the program storage area 26P, and the basic processing program 31A is loaded into the control unit 21 and has already started processing. Further, it is assumed that an audio content file 36 ₁ used in the application program 32A ₁ is stored in the content storage area 26C. Further, it is assumed the engine use flag 35 ₁ is ON.

First, the basic processing program 31A that has received an application execution instruction issued when the user operates the operation unit 12 starts loading the application program 32A ₁ corresponding to the execution instruction. Then, the basic processing program 31A performs analysis and header portion 33 ₁ of the load in the application program 32A _1, it refers to the value of engine use flags 35 ₁ included in the header portion 33 _1. As a result of such reference, the control unit 21 recognizes that the engine use flag 35 ₁ is ON. When the basic processing program 31A completes loading of the program unit 34 ₁ included in the application program 32A ₁ , the basic processing program 31A activates the application program 32A ₁ .

If it is necessary to draw characters or graphics during the execution of the application program 32A ₁ in addition to the development of the image content file, the application program 32A ₁ sends a drawing command to the basic processing program 31A. Also, if required the deployment of audio content file 36 ₁ while the application program 32A ₁ executing the application program 32A ₁ sends play (sound reproduction) command to the basic processing program 31A. If the audio reproduction is to be stopped during the development of the audio content file 36 ₁ , the application program 32A ₁ sends a reproduction end command to the basic processing program 31A. Basic processing program 31A and the sequence of processing in the engine section 25 corresponding to each instruction from such an application program 32A ₁ is shown in FIG.

As shown in FIG. 6, when the drawing instruction # 1 from the application program 32A _{1 is} received in a state where the development of the audio content file 36 ₁ is not started and the engine unit 25 is not used, in step S11. basic processing program 31A determines whether or not the engine use flag 35 ₁ is ON. Since engine use flag 35 ₁ as described above is ON, the basic processing program 31A executes drawing processing using conventional processing resource of the control unit 21.

Upon receiving the reproduction command is a development command of the audio content file 36 ₁ from the application program 32A _1, the basic processing program 31A sends a reproduction command unconditionally to the engine unit 25. As a result, the reproduction process is a development processing of the audio content file 36 ₁ in the engine section 25 is started.

During expansion processing of the audio content file 36 ₁ in the engine section 25, when receiving the drawing command # 2 from the application program 32A _1, in step S12, as in the case of step S11, the basic processing program 31A is controlled The drawing process is executed using the normal processing resources of the unit 21. That is, when the execution of step S12, the expansion processing of the audio content file 36 ₁ by the engine unit 25, a rendering process using the normal processing resource of the control unit 21 according to the basic processing program 31A is executed in parallel.

Thereafter, upon receiving a playback end command, which is the end of expansion of the audio content file 36 ₁ , from the application program 32 A ₁ , the basic processing program 31 A immediately sends a playback end command to the engine unit 25. As a result, the reproduction process is completed is a development processing of the audio content file 36 ₁ in the engine unit 25.

After the expansion process of the audio content file 36 ₁ is finished and the engine unit 25 is not used, when the drawing command # 3 is received from the application program 32A ₁ , the above-described step S11 is performed in step S13. Similarly to the case, the basic processing program 31 </ b> A executes drawing processing using the normal arithmetic processing resources of the control unit 21. Thereafter, while using the engine unit 25 in response to the reproduction command from the application program 32A _1, when a drawing command from the application program 32A ₁ is always rendering operation utilizing a conventional processing resource is Done.

  Note that when executing an application with the engine usage flag set to OFF, the playback process and the rendering process corresponding to the rendering command from the application do not conflict with each other. Is executed using the engine unit 25. If there is a conflict between the playback process and the drawing process, the basic processing program 31A reports an error to the application.

As described above, in the present embodiment, when the engine use flag in the application program 32A _j is set to ON, the engine unit 25 is used for the reproduction process regardless of whether there is a conflict with the drawing process. Use. For this reason, an engine is always used for the reproduction processing of content objects such as 3D sound data and moving image data in which the amount of data to be processed is enormous. On the other hand, drawing processing by an application that may conflict with playback processing is always executed using normal processing resources, and the engine unit 25 is not used.

  Therefore, according to the present embodiment, it is possible to prevent contention related to the use of the engine unit 25 when executing an application accompanied by a content object reproduction process and a drawing process.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIGS. In the description of the present embodiment, a cellular phone device will be described as an example.

<Configuration>
As shown in FIG. 7, the mobile phone device 10B according to the present embodiment replaces the basic processing program 31A in the program storage area 26P of the storage unit 23 as compared with the mobile phone device 10A of the first embodiment. The basic processing program 31B is stored, and only the application programs 32B ₁ , 32B ₂ ,... Are stored instead of the application programs 32A ₁ , 32A ₂ ,. Hereinafter, description will be made by paying attention to this difference.

The basic processing program 31B is different from the basic processing program 31A of the first embodiment in that (i) the engine use flag is not referenced, and (ii) when the engine unit 25 is not in use, the application program 32B _j ( (j = 1, 2,...), when a drawing command or a playback command is received, a drawing command or a playback command is immediately sent to the engine unit 25. (iii) While using the engine unit 25, the application program 32B _j When the reproduction command is received, the reproduction command is sent to the engine unit 25 after it is no longer in use, and (iv) the drawing from the application program 32B _j while using the engine unit 25 When an instruction is received, a difference is that a drawing process is normally performed using a calculation resource.

Also, the application programs 32B ₁ , 32B ₂ ,... Are different from the application programs 32A ₁ , 32A ₂ ,... In the first embodiment only in that they do not have an engine use flag.

<Operation>
Next, a description will be given mainly focusing on the usage management method of the engine unit 25 in the mobile phone device 10B configured as described above. It is assumed that the basic processing program 31B and the application program 32B ₁ are stored in the program storage area 26P, and the basic processing program 31B is loaded in the control unit 21 and has already started processing. Further, it is assumed that an audio content file 36 ₁ used in the application program 32B ₁ is stored in the content storage area 26C.

First, the basic processing program 31B that has received the application execution instruction issued when the user operates the operation unit 12 is similar to the basic processing program 31A in the first embodiment. The loading of the program 32B ₁ is started. Then, the basic processing program 31B has completed the loading of the application program 32B _1, to start the application program 32B _1.

If it is necessary to draw characters or graphics during the execution of the application program 32B ₁ in addition to the development of the image content file, the application program 32B ₁ sends a drawing command to the basic processing program 31B. Also, if required the deployment of audio content file 36 ₁ while the application program 32B ₁ executing the application program 32B ₁ sends play (sound reproduction) command to the basic processing program 31B. When the audio reproduction is stopped during the development of the audio content file 36 ₁ , the application program 32B ₁ sends a reproduction end command to the basic processing program 31B. The basic processing program 31B corresponding to each command from the application program 32 ₁ and the processing sequence of the engine unit 25 are shown in FIG.

As shown in FIG. 8, when the rendering of the audio content file 36 ₁ is not started and the engine unit 25 is not used, the basic processing program is received when the drawing command # 4 is received from the application program 32B _1. 31B determines whether the engine unit 25 is in use. In this case, since the result of the determination is negative, the basic processing program 31B immediately sends a drawing command to the engine unit 25. Receiving this drawing command, the engine unit 25 executes a drawing process in step S21.

Upon receiving the reproduction command is a development command of the audio content file 36 ₁ from the application program 32B _1, the basic processing program 31B, first determines whether or not the engine unit 25 is in use. If the result of the determination is negative, the basic processing program 31B immediately sends a regeneration command to the engine unit 25. On the other hand, if the result of the determination is affirmative, the basic processing program 31B waits until the engine unit 25 is not in use, and the basic processing program 31B sends a regeneration command to the engine unit 25. Receiving the regeneration command, the engine unit 25 executes regeneration processing in step S22.

  In addition, in FIG. 8, the example in case the result of the said determination becomes negative is shown.

During expansion processing of the audio content file 36 ₁ in the engine section 25, when receiving the drawing command # 5 from the application program 32B _1, the basic processing program 31B determines whether or not the engine unit 25 is in use. In this case, since the result of the determination is affirmative, the basic processing program 31B executes the drawing process using the normal arithmetic processing resource in step S23.

Thereafter, when receiving the reproduction end instruction is a development end of the audio content file 36 ₁ from the application program 32B _1, the basic processing program 31B immediately sends a reproduction end command to the engine unit 25. As a result, the reproduction process is completed is a development processing of the audio content file 36 ₁ in the engine unit 25.

After the expansion processing of the audio content file 36 ₁ is finished and the engine unit 25 is not used, when the drawing command # 6 is received from the application program 32B ₁ , the basic processing program 31A 31B determines whether the engine unit 25 is in use. In this case, since the result of the determination is negative, the basic processing program 31B immediately sends a drawing command to the engine unit 25. The engine unit 25 that has received this drawing command executes a drawing process in step S24. Thereafter, in response to the drawing command or a reproduction command from the application program 32B _1, while utilizing the engine unit 25 as much as possible, the drawing process or reproduction process is performed.

  As described above, in the present embodiment, the engine unit 25 is always used for the reproduction process. Then, when competing with the reproduction process, the drawing unit is executed using the normal processing resource without using the engine unit 25, and when not competing with the reproduction process, the engine unit 25 is used. Then, the drawing process is executed. Therefore, it is possible to execute the drawing process and the reproduction process while maximizing the efficiency of use of the engine unit 25.

The only difference is that the basic processing program 31C is stored.

The basic processing program 31C is different from the basic processing program 31B of the second embodiment in that (i) the engine use flag is not referred to, and (ii) when the engine unit 25 is not in use, the application program 32B _j ( (j = 1, 2,...) When a drawing command or a playback command is received from the engine unit 25, a drawing command or a playback command is immediately sent to the engine unit 25, and (iii) an application program is being used while using the engine unit 25. When a playback command is received from 32B _j, it is common in that the playback command is sent to the engine unit 25 after waiting for it to be no longer in use. On the other hand, the basic processing program 31C is different from the basic processing program 31B of the second embodiment in that the running application is temporarily stopped during the development of the content file using the engine unit 25.

The loading of the program 32B ₁ is started. When the basic processing program 31C completes loading of the application program 32B ₁ , the basic processing program 31C activates the application program 32B ₁ .

If it is necessary to draw characters or graphics during the execution of the application program 32B ₁ in addition to the development of the image content file, the application program 32B ₁ sends a drawing command to the basic processing program 31C. Also, if required the deployment of audio content file 36 ₁ while the application program 32B ₁ executing the application program 32B ₁ sends play (sound reproduction) command to the basic processing program 31C. When the audio reproduction is stopped during the development of the audio content file 36 ₁ , the application program 32B ₁ sends a reproduction end command to the basic processing program 31C. The basic processing program 31C corresponding to each command from the application program 32 ₁ and the processing sequence of the engine unit 25 are shown in FIG.

As shown in FIG. 10, when the rendering of the audio content file 36 ₁ is not started and the engine unit 25 is not used, when the drawing command # 7 from the application program 32B _{1 is} received, the basic processing program 31C immediately sends a drawing command to the engine unit 25. The engine unit 25 that has received this drawing command executes a drawing process in step S31.

Upon receiving the reproduction command is a development command of the audio content file 36 ₁ from the application program 32B _1, the basic processing program 31C, first, determines whether or not the engine unit 25 is in use. If the result of the determination is negative, the basic processing program 31C immediately sends a regeneration command to the engine unit 25. On the other hand, if the result of the determination is affirmative, the basic processing program 31C waits until the engine unit 25 is not in use, and the basic processing program 31C sends a regeneration command to the engine unit 25. As a result, in step S32, the engine unit 25 starts the reproduction process.

Then, the basic processing program 31C that has transmitted the reproduction command temporarily stops the application program 32B ₁ .

Thereafter, upon receipt of a playback end command, which is the end of expansion of the audio content file 36 ₁ , from the application program 32 B ₁ , the basic processing program 31 C immediately sends a playback end command to the engine unit 25. As a result, the reproduction process is completed is a development processing of the audio content file 36 ₁ in the engine unit 25.

Then, the basic processing program 31C that has transmitted the reproduction end command resumes the execution of the application program 32B ₁ .

Upon receiving the rendering command # 8 from the application program 32B ₁ whose execution has been resumed after the expansion processing of the audio content file 36 ₁ is finished and the engine unit 25 is not used, the basic processing program 31C Immediately, a drawing command is sent to the engine unit 25. Receiving this drawing command, the engine unit 25 executes a drawing process in step S33. Thereafter, while temporarily stopped the application program 32B ₁ in response to the reproduction command from the application program 32B _1, drawing process and a reproduction process is executed.

  As described above, in the present embodiment, use of the engine for rendering processing is limited by temporarily suspending the application during a period in which the engine is used for playback processing. For this reason, it is possible to prevent a competition regarding the use of the engine from occurring between the reproduction process and the drawing process.

  Therefore, according to the present embodiment, it is possible to perform the rendering process and the playback process while preventing the competition of use of the engine unit 25 due to the content object playback process and the application rendering process.
