Detailed ways

Certain terms are used in the text of this patent application to refer to particular elements. It should be understood by those skilled in the art that hardware manufacturers may use different terms to refer to the same element. This description and subsequent patent applications do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. "Include" mentioned in the entire specification and subsequent claims is an open-ended term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" here includes any direct and indirect means of electrical connection. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means. the

FIG. 1 shows an information processing system 100 according to an embodiment of the present invention. As shown in FIG. 1 , the information processing system 100 includes: a processing module 101 , a first electronic device 103 , a second electronic device 105 and a third electronic device 107 . The first electronic device 103, the second electronic device 105, and the third electronic device 107 are respectively used to perform a first task, a second task, and a third task, and the first, second, and third electronic devices 103, 105 and 107 do not process the first, second and third jobs simultaneously. The processing module 101 is used for controlling the first, second and third electronic devices 103 , 105 and 107 without using an operating system. the

Figure 2 and Figure 3 show the action of the information processing system according to the embodiment of the present invention, please refer to Figure 1, Figure 2 and Figure 3 interactively to better understand the technical features of the present invention. FIG. 2 shows the operation of the information processing system according to the present invention when the third electronic device is not in operation. As shown in FIG. 2 , the first electronic device 103 will be unable to perform the first task at a specific time T. This specific time T may be the delay time required for waiting for instructions or data or the waiting time required by the first electronic device 103 itself. , or other similar time periods. At this time, the processing module 101 will control the second electronic device 105 to perform the second task within a specific time T, and when the specific time T ends, if the first electronic device 103 still needs to perform the first task, it will make the second electronic device 103 105 stops executing the second task and enables the first electronic device 103 to resume executing the first task. Alternatively, if the first electronic device 103 does not need to perform the first task after a certain time T, the second electronic device 105 will continue to perform the second task. In this example, the concept of a state machine (state machine) can be added, that is, a state parameter is given to the first electronic device 103 and the second electronic device 105, and the first electronic device and the second electronic device will perform different operations according to the state parameter. action. That is to say, the first electronic device 103 also processes the first task, but due to different state parameters, different processing methods are implemented for the first task. Since the concept and application of the state machine are well known to those skilled in the art, they will not be repeated here. the

FIG. 3 shows the situation when the third electronic device is operable. As shown in FIG. 3 , when the first electronic device 103 cannot execute the first job within a specific time T, the processing module 101 will first determine whether it is suitable to execute the second job or the third job without using the job processing system. If it is suitable to perform the second task, then control the second electronic device 105 to perform the second task within a specific time T, and when the specific time T ends, if the first electronic device 103 still needs to perform the first task, it will make the second electronic device 103 perform the second task. The device 105 stops executing the second task and enables the first electronic device 103 to resume executing the first task. Similarly, if it is suitable to perform the third task within the specified time T, the processing module 101 controls the third electronic device 107 to perform the third task within the specified time T, and when the specified time T ends, if the first electronic device 103 still needs Executing the first task will cause the third electronic device 107 to stop executing the third task and allow the first electronic device 103 to resume executing the first task. After the first job is processed, the processing module 101 will also determine that it is suitable to process the second job or the third job. According to the same concept, when the second electronic device 105 is processing the second job and must stop processing the second job within the second specific time, the processing module 101 will determine that the second specific time is appropriate for the second specific time without executing the operating system. Handle the first job or the third job. the

One of the methods for judging whether it is suitable to perform the first job, the second job or the third job is to give the first, second and third electronic devices 103, 105 and 107 a priority order, and then according to the priority order Decide which job to tackle first. Therefore, the priority order in this example is that the first electronic device 103 is greater than the second electronic device 105 , and the second electronic device 105 is greater than the third electronic device 107 . Therefore, the processing module 101 will first let the first electronic device 103 process the first task, and when the first electronic device 103 cannot process the first task within a certain time T, it will first let the second electronic device 105 process the first task within a certain time T. The second task, if the second electronic device 105 cannot process the second task at this time, the third electronic device 107 is allowed to process the third task. Similarly, when the second electronic device 105 is processing the second job and must stop processing the second job within a second specified time, the processing module 101 will first judge whether there is still the first job to be executed, and if so, execute the first job. work, the third work is performed when there is no first work. In short, the concept of "executing a job, and judging which job is suitable for execution during the pause time" is not limited to the above-mentioned embodiments, and it can be presented in any combination or form. It also does not depart from the scope of the present invention. the

One of the reference factors for determining the priority order can be the importance of the work. The more important work must be completed first, the higher priority order can be given. Such description is only for example, not to limit the present invention . Of course, methods other than the priority order can also be used to determine the work to be processed first (for example: the data volume of the work, etc.), and such changes should also be within the scope of the present invention. the

In addition, the processing module 101 can be processed by a single processing unit as in the prior art. However, as shown in FIG. 1 , the first processing unit 109 and the second processing unit 111 can also be used for processing. When a single processing unit is used for processing, a stronger processing unit is required because all the control needs to be undertaken, which will increase the cost. However, if two processing units are used, the functions of the two processing units can be divided. For example, in the embodiment shown in FIG. 1 , the first processing unit 109 may be responsible for setting state parameters or setting priority order, and the second processing unit 111 may be responsible for controlling the actions of each electronic device, so It will be possible to use two less powerful processing units at a lower cost than using one more powerful processing unit. Moreover, the processing module 101 according to the embodiment of the present invention is not limited to using two processing units, and it can also use more than two processing units. the

4 and 5 show an information processing method corresponding to the information processing system 100 shown in FIG. 1 . Wherein, FIG. 4 shows the steps when only two electronic devices are in operation, and FIG. 5 shows the steps when more than two electronic devices are in operation. the

The methods shown in Figure 4 include:

Step 401:

Handle the first job. the

Step 403:

A second job is processed, wherein the first and second jobs are not processed concurrently. the

Step 405:

In the case of not executing an operating system, when processing the first job, if the processing of the first job must be stopped within a first specific time, the second job is processed within the first specific time. the

The methods shown in Figure 5 include:

Step 501:

Determine a priority order for multiple jobs. the

Step 503:

A first job is selected from the plurality of jobs according to the priority order, and the first job is processed. the

Step 505:

In the case of not executing an operating system, when processing the first job and must stop processing the first job within a first specified time, or when the first job is processed, select the second job from multiple jobs according to the priority order job, and handle the second job. the

Other detailed technical features have been disclosed in the above examples, so they will not be repeated here. the

FIG. 6 shows a situation where the concept of an information processing system according to an embodiment of the present invention is used on a television system 600 . As shown in Figure 6, the TV system 600 includes a processing module 601, which is used to control the relevant electronic devices of the TV system 600 such as a TV signal receiver 603, a SI processor 605, a video path microprocessor 607, a video decoding 609, drawing engine element 611, scaler 613, digital signal processing unit 615, audio decoder 617, MPEG video decoder 619, and the like. The detailed structures and operation modes of these components related to the television system are well known to those skilled in the art, so they will not be repeated here. The action mode of the TV system 600 is shown in FIGS. 1 to 5. A priority order can be given to the relevant electronic devices, and then the electronic device with a higher priority order (such as a TV signal receiver) is allowed to process its related work first, and then When the electronic device cannot handle its related work within a specific time, the processing module 401 judges which one of the other electronic devices has a higher priority (such as a video decoder), and lets this electronic device (video decoder) Execute its related work within a certain period of time. Other technical features have been described in detail in the above description, so they will not be repeated here. One of the ways of determining the priority order is that if the work of the electronic device is less likely to be interrupted, it will be given a higher priority. For example, TV signal receivers must give higher priority because of the consideration of uninterruptible signal reception, and if the graphics engine component is used to display screens such as program menus, due to the tolerable delay higher degree, it can be given a lower priority. Moreover, in this embodiment, the first processing unit 621 is an 8-bit processor, and the second processing unit 623 is a 32-bit processor, so the second processing unit 623 is used to process more complex actions, and The first processing unit 621 is used for processing relatively simple actions, such as responsible for setting state parameters or setting priority order, but it is not intended to limit the present invention. the

FIG. 7 shows a schematic diagram of the operation of the television system 600 according to the present invention. As shown in Figure 7, there are three working multifunctional main items (OSD Main Menu), information coding (in this example, information coding actions that meet the requirements of MHEG, Multimedia and.Hypermedia information coding Expert Group) and digital storage media commands and control (DSMCC, Digital Storage Medium Command and Control). The three jobs can be switched among each other, and the job with a higher priority (for example, copying data from the buffer of the TV signal receiver) cannot be executed for a certain time (in this case, the delay time) When the specified time is over, the delay function can be called to perform other tasks, and when the specified time is over, the tasks with higher priority will resume execution. In this example, the delay function is invoked only when the delay time is greater than 1 ms, otherwise, the delay function is not invoked, but this is not intended to limit the present invention. It should be noted that a job is not limited to be performed by one electronic device, but can be jointly performed by a group of electronic devices. Moreover, if the priority order of the work that a group of specific electronic devices is responsible for is higher than the priority order of the work that is responsible for another group of electronic devices, the priority of this group of specific electronic devices will be higher than that of the other group, but in the same In the group of electronic devices, the order of priority is different. the

A schematic diagram illustrating the operation of a television system 600 according to the present invention is included in FIG. 8 . As shown in Figure 8, work can be divided into main work (main state) and sub-work (sub state), and a main work can include many sub-works. For example, OSD Main Menu can include subtasks such as Initial/Idle/EPGtimer/CleanUp/Standby/Scan/EPG/Exit/ChannelChange/USB. A group of electronic devices are jointly responsible for the main job and handle the sub-jobs below. the

The above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the present invention. the
