Description

  The present invention belongs to the technical fields of an information processing device, an information processing method, and an information processing program, and more specifically, an information processing device connected to a plurality of sub-processing devices and information processing executed in the information processing device The method belongs to the technical field of the information processing program.

  In recent years, portable information processing apparatuses represented by, for example, portable telephones have been widely used. And since these information processing apparatuses usually have a built-in battery as a power source, in order to extend the drive time, each member constituting the information processing apparatus or the information processing apparatus Power saving in the peripheral devices connected to is an essential issue.

  Here, as one measure for power saving in the peripheral device, a method is used in which each peripheral device is shifted to a hibernation state as necessary to suppress power consumption in each peripheral device. More specifically, each peripheral device is directly shifted to a dormant state by the CPU in the information processing apparatus to which each peripheral device is connected, and when returning from the dormant state, for example, so-called hardware in the CPU The return control of each peripheral device using a timer was performed.

  However, such conventional configuration and control for power saving have the following problems, for example.

Therefore, it is possible to flexibly change a processing content in the peripheral device itself. There was a problem that it was not possible to cope with.

  Second, when each peripheral device is expanded, it is difficult to change or add a command, and in that case, the CPU itself needs to control the command execution timing and the execution content. was there.

  Furthermore, thirdly, even when each peripheral device shifts to a dormant state, the processing is performed under the control of the CPU connected to the peripheral device, and as a result, the CPU that performs overall control of each peripheral device. There has been a problem that an increase in processing load and an increase in power consumption have been caused.

On the other hand, as conventional techniques corresponding to these problems, for example, there are techniques described in Patent Documents 1 and 2 below. That is, in the prior art described in each patent document, a plurality of bidirectional queues for controlling peripheral devices from the CPU in the information processing apparatus are set in advance, and are configured separately from the CPU in the information processing apparatus. When the task control unit is activated, the task control unit executes the tasks in the bidirectional queue separately from the operation of the CPU (in other words, without driving the CPU), so that the information processing apparatus including the CPU as a whole To save power.

  Finally, when the processing of the content of the task information 60E is completed, the content of the jump information 22 of the header information 70 is blank, so that the peripheral device P1 set in advance from the task control unit 2 to the CPU 1 is set. A notification indicating that all the processes from P3 to P3 are completed is output, and the CPU 1 returns from the hibernation state.

  As described above, according to the configuration of the information processing apparatus S according to the embodiment, the CPU 1 starts after the task control unit 2 starts processing in the peripheral devices P1 to P3 based on the contents of each bidirectional queue information 10 and the like. Shifts to the dormant state, so that the processing in each peripheral device P1 to P3 proceeds while the CPU 1 is dormant, so that each peripheral device P1 to P3 functions while suppressing power consumption in the information processing apparatus S. Can be made.

  In addition, since each task information 30 or the like constituting one bidirectional queue information 10 or the like includes the forward waiting time information 33 and the backward waiting time information 35, the processing corresponding to each task information 30 or the like is executed. The power consumption of the information processing apparatus S can be reduced while finely controlling the time axis.

  Therefore, the processing of each peripheral device P1 to P3 can be finely controlled including the control of the execution timing of the processing corresponding to each task information 30 and the like while suppressing the power consumption as the information processing apparatus S.

  Further, since each bi-directional queue information 10 or the like includes jump information 23 for shifting to processing corresponding to the task information 30 or the like in the other bi-directional queue information, between the plurality of peripheral devices P1 to P3 By configuring each bidirectional queue information so as to execute necessary processing while freely shifting the process, more advanced and complicated processing can be executed by the plurality of peripheral devices P1 to P3.

  Furthermore, since the power consumption as the CPU 1 is suppressed, it is possible to extend the driving time as the portable information processing apparatus S that supplies driving power independently.

(II) Modified Embodiment Next, a modified embodiment according to the present invention will be described.

  First, as a first modification, the jump information 23 can be included in each task information 30 or the like.

  In the case of this first modification, each task information 30 etc. includes jump information 23 for shifting to the processing corresponding to the task information 30 etc. in the other bidirectional queue information. By configuring each bidirectional queue information so as to execute necessary processing while freely moving between the peripheral devices P1 to P3, more advanced and complicated processing is executed by the plurality of peripheral devices P1 to P3. Can do.

  Furthermore, as a second modification, in the above-described embodiment, it is assumed that the contents of each bidirectional queue information 10 and the like are not changed during execution of processing in each peripheral device P1 and the like. It is also possible to change the contents of the bidirectional queue information 10 and the like during the execution of.

  That is, for example, even when the jump information 23 is not blank as in the above-described embodiment, every time all the processes in each peripheral device P1 and the like are completed, the CPU 1 is notified of the completion while proceeding to the next process. It is good also as a structure. In this case, the CPU 1 is notified when the processing of the content of the last task information is executed for each peripheral device P1 or the like.

  Then, the CPU 1 that has received the notification of the completion changes (updates) the jump information 23 and the end task number information 22 in the bidirectional queue information 10 and the like corresponding to the peripheral device that is executing the processing at the timing when the notification is received. ) At least one of processing, or processing for changing (updating) the contents of the bidirectional queue information 10 or the like corresponding to the peripheral device that is to execute processing next to the peripheral device that is executing processing at the timing of receiving the notification I do.

  With this configuration, bidirectional processing corresponding to the other peripheral devices P1 to P3 that are executing the processing at the timing when the processing to be executed in one peripheral device P1 or the like is completed and a notification to that effect is output. Processing in at least one of the jump information 23 and the instruction information such as the end task information 30 included in the queue information 10 etc. is changed, and the processing in the other peripheral devices P1 to P3 based on the changed information Therefore, during the execution of a series of processes in the peripheral devices P1 to P3, the contents of the process can be dynamically changed.

  Further, the processing is executed next to the other peripheral devices P1 to P3 that are executing the processing at the timing when the processing to be executed in one peripheral device P1 or the like is completed and the completion information is output. Since the contents of the bidirectional queue information corresponding to the other peripheral devices P1 to P3 to be changed are changed, and the processing in the other peripheral devices P1 to P3 is further controlled using the bidirectional queue information whose contents are changed. During the execution of a series of processes in the peripheral devices P1 to P3, the processing contents in the subsequent peripheral devices P1 to P3 can be dynamically changed.

  Finally, as a third variation, if the notification timing to the CPU 1 in the second variation described above is performed not only at the end of the process in each peripheral device P1 etc., but also at the start of the process, It is also possible to change the jump information 23 in the peripheral device P1 or the like that is executing the started processing.

  In this case, the content of the jump information 23 included in the corresponding bidirectional queue information is changed at the timing when processing to be executed in one peripheral device P1 or the like is started, and the jump information 23 after the change is changed. Therefore, the processing content can be dynamically changed during execution of a series of processing in each of the peripheral devices P1 to P3.

  It should be noted that the programs corresponding to the timing charts shown in FIGS. 3 and 4 are recorded on information recording media such as a flexible disk and a hard disk, respectively, or acquired and recorded via the Internet, etc. Can be used as the CPU 1 or the task control unit 2 according to the embodiment.

  As described above, the present invention can be used in the field of information processing apparatuses that perform information processing using bidirectional queues, and is particularly portable (ie, autonomously supplies power). When applied to the field of information processing apparatuses, particularly remarkable effects can be obtained.
