Description

Terminal and data processing method

technical field

The present invention relates to the technical field of communications, and in particular, to a terminal and a data processing method.

Background technique

The traditional single-standby architecture is shown in Figure 1. There is only one mobile phone baseband chip (Modem), one processor (CPU), one memory (RAM) and one storage area (EMMC). All data from external devices are processed by a CPU, and all data are stored in a RAM and EMMC.

The disadvantages of existing solutions are:

(1) In the traditional single-standby architecture, the CPU has a heavy task and needs to process all data from external devices. With the rapid development of smart phones, the number of external devices continues to increase, and the amount of data in smart phones is very large. Single CPU processing will lead to The data processing speed is significantly slowed down, affecting user experience.

(2) All data is processed by a single CPU, and the data is mixed together. The security and privacy of important data such as the user's contacts, information, call records, and security passwords cannot be effectively guaranteed, threatening the security of the user's important data.

(3) All data is stored by a single RAM and EMMC. The rapid expansion of smart machine data volume seriously affects the stability of RAM and EMMC. All data stored in the same place also seriously affects the security of personal private information data, which is easy to be stolen. Third-party apps peep and steal. In addition, according to experience, data confusion in RAM and EMMC can easily cause mobile phone crashes and affect user experience.

At present, there is no corresponding technology to solve the problems faced by related technologies.

In order to improve data security, the terminal is equipped with multiple processors, and some of the processors are designated to process the user's private data, and the rest of the processors are used to process the user's non-private data, so that many data can be divided into multiple categories. Processing can not only speed up the response speed, but also ensure data security and improve system stability.

Since the external device is connected to the first processing unit, and the data from the external device includes private data and non-private data, in order to ensure that the private data and non-private data from the external device are respectively processed by different processors, the A monitoring module is set in the processing unit to judge the type of data from the external device, that is, it is divided into private data and non-private data to ensure the accuracy of data classification, and different types of data are sent to different processing units respectively. The security of data processing is ensured.

Private data refers to data that belongs to personal privacy for users, such as passwords, account numbers, SMS content, email content, financial data, etc., while non-private data refers to data that does not belong to personal privacy for users. Examples include downloaded music, e-books, radio data, web news, etc. External devices refer to other related devices of the terminal other than processors and communication units, such as screens, sensors, Bluetooth, WIFI, cameras, etc.

It should be understood that in addition to classifying data according to user privacy, other classification methods may also be used, for example, data related to contacts is processed by the first processing unit, and other data is processed by the second processing unit.

In the above technical solution, preferably, further comprising: a first storage unit, connected to the first processing unit, for storing the private data processed by the first processing unit; a second storage unit, connected to The second processing unit stores the non-private data processed by the second processing unit.

The first storage unit and the second A storage unit may be a memory and/or a memory. On the other hand, since private data and non-private data are stored in different spaces and processed by different processors, the data processing speed is improved.

In the above technical solution, preferably, it further includes: an update unit, which updates the judgment conditions for filtering the data according to the received update instruction, so that the monitoring module performs private data and non-private data according to the updated judgment conditions. Judgment on private data.

In this technical solution, with the increase of terminal services, the types of user's private data will also change. For example, in communication services, SMS, address book, etc. belong to the user's private data; in the terminal system, the switch password, Application protection passwords, terminal anti-theft passwords, and screen unlock passwords also belong to the user's private data. By updating the judgment conditions for data screening, the data screening is made more accurate, thereby ensuring the security of the user's private data.

In the above technical solution, preferably, the determination condition includes classifying all applications on the terminal into protected applications and unprotected applications, the private data belongs to the data under the protected applications, and the non-protected applications Private data belongs to the data under the unprotected application.

In this technical solution, the user or manufacturer can set the conditions for determining the type of data. Specifically, all applications in the terminal can be divided into protected applications and unprotected applications, so that when the monitoring module receives data, The attribute of the data is judged by judging the type of the application to which the data belongs. If the data belongs to a protected application, the data is private data, otherwise, it is non-private data. For example, a chat tool can be regarded as a protected application, and a music player can be regarded as an unprotected application, and then it can be determined that the data generated by the chat tool belongs to private data, while the data generated by the music player belongs to non-private data. Certainly, the user or the manufacturer may also set other determination conditions as required, such as the data related to the contact is private data, other data is non-private data, and so on.

Through such a processing mechanism, it can ensure that the relatively important and urgent business data of the user is processed first. And it will not affect the processing of other business data. Specifically, a flag can be set in the monitoring module. When the flag is at a low level, the first processing unit works, and when the flag is at a high level, the second processing unit works. For example, when the user is listening to music ( It belongs to non-private data, which uses the speaker of the external device and is processed by the second processing unit), and a sudden call from the mobile phone (belongs to private data, which should be processed by the first processing unit and needs to use the speaker of the external device), then the monitoring module will The flag position is low level, and the incoming call data is handed over to the first processing unit for processing. After the first processing unit finishes processing the incoming call, the monitoring module sets the flag position as high level, and the second processing unit continues to control the external device speaker to play music.

Similarly, when the second processing unit needs to interact with external devices, it also needs to send a suspension notification to the first processing unit to ensure that the most urgent and recent business data can be processed first.

Fig. 4 shows a schematic diagram of a terminal according to an embodiment of the present invention.

As shown in Figure 4, the present invention has increased a CPU, RAM and EMMC on the basis of related technology, processes different data by different CPU like this, and different RAM and EMMC store different data.

For example, it is defined that CPU1 only processes personal private information data (data of protected applications), and through the monitoring module set in CPU1, the data of protected applications is filtered out from the data from external devices (wherein, protected applications include contact , information, password protection, etc.), which are processed by the dedicated CPU1 and stored in the dedicated memory RAM1 and EMMC1, thereby ensuring the security of the user's personal private information data; defining that CPU2 only processes public information data facing the society (data of unprotected applications ), through the monitoring module set in CPU1, the data from external devices is screened out from the data of unprotected applications (wherein, unprotected applications include browser, display, photo taking, simple music playback and video playback, radio, etc. ), processed by the dedicated CPU2, and stored in the dedicated memories RAM2 and EMMC2. In this way, the data of the protected application and the data of the unprotected application are processed and stored separately, avoiding the mixing of data of different security levels, which can ensure the security of the user's private data, and can greatly improve the processing time of different data. Improve user experience.

The memory corresponding to each processing unit may be a storage medium such as nandflash in addition to EMMC.

Fig. 5 shows a flowchart of a processing method of a first processing unit according to an embodiment of the present invention.

As shown in Figure 5, the flow of the processing method of the first processing unit is as follows:

Step 502, the first processing unit CPU1 processes the private information from the external device screened out by the monitoring module set in the CPU1. It is defined that the first processing unit only processes personal private information data, and applications such as contacts, information, and password protection are set as protected applications, and the first processing unit only processes data of protected applications. Step 504, storing the private information in the first storage unit (RAM1 and EMMC1), wherein the first storage unit includes a memory and a memory. All data of the protected application is stored in the first storage unit.

Step 506, hand over the private information to the protected application for processing. Thereby ensuring the data security of storing and processing personal private information.

Of course, a second processing unit may also be defined to process private information.

Fig. 6 shows a flowchart of a processing method of the second processing unit according to an embodiment of the present invention.

As shown in Figure 6, the flow of the processing method of the second processing unit CPU2 is as follows:

Step 602, the second processing unit processes the non-private information from the external device screened out by the monitoring module set in the CPU1. It is defined that the second processing unit only processes non-private information data (that is, public information data facing the society), and applications such as taking photos, displaying, and browsing web pages are set as unprotected applications, and the second processing unit only processes data of unprotected applications.

Step 604, storing the non-private information on the second storage unit (RAM2 and EMMC2), wherein the second storage unit includes a memory and a memory. Data of unprotected applications are all stored in the second storage unit.

Step 606, hand over the non-private information to the non-protected application for processing. Thereby ensuring the data security of storing and processing personal private information.

Fig. 7 shows a flowchart of a processing method of a monitoring module according to an embodiment of the present invention.

As shown in FIG. 7, the process flow of the processing method of the monitoring module according to the embodiment of the present invention is as follows:

Step 702, the monitoring module set in CPU1 screens the data from the external device. When the external device interacts with the user, not only the user's private information data, such as wireless network password and other data, but also data that can be made public, such as playing music and other data, will be generated. Since the external devices are connected to the CPU1, a monitoring module is set in the CPU1, and the protected data and unprotected data from one or more external devices are screened out by the monitoring module.

Step 704, the monitoring module judges whether the data from the external device is private data or non-private data.

Step 706, when the monitoring module determines that the data from the external device is private data, the private data is handed over to CPU1, RAM1 and EMMC1 for processing and storage, and these data interact with the external device through CPU1.

Step 708, when the monitoring module determines that the above data is non-private data, hand over the non-private data to CPU2, RAM2 and EMMC2 for processing and storage.

Therefore, in this embodiment, data filtering rules are preset in the monitoring module, and all application data are classified into core applications and non-core applications. Core applications are protected applications, and non-core applications are not protected. Protected applications, core applications can be applications that contain user privacy data, such as voice service data (address book, call records, information), email in data service data, account information saved, recording in multimedia applications, downloading through payment Audio and video, power on and off passwords in the system, mobile phone anti-theft passwords, screen unlock passwords, data information encryption in file managers, backup applications, notepads, non-core applications are applications that do not involve user privacy data, such as data business data browsers, webcams, simple display applications, radios. The monitoring module judges the data in the external device according to the preset filtering rules, and judges whether the data is private data, and if the data is private data, sends the private data to a processor dedicated to processing private data for processing.

Since the screening rules are the basis for distinguishing private data from non-private data, and the accuracy of the basis will affect the accuracy of data distinction, in order to ensure that the basis can be updated according to the development of applications and businesses, when new applications are found, or new services, whether to update the screening rules can be determined according to whether the new applications and new services involve personal privacy, that is, new applications and new services that involve private data will be classified into data categories that involve private data, and those that do not involve private data New applications and new services are classified into data categories involving non-private data. For example, after the terminal newly downloads a psychological FM application, it is determined that the application does not involve private data, then the application can be classified into non-core application categories, and the division can be manually selected by the user, or it can be based on other terminal Judging the application to automatically determine whether the application is an application that does not involve private data.

In addition, the monitoring module is also used to send a suspension notification to the CPU2 used to process non-private data to interrupt the CPU2 being processed The business data is in a waiting state. When CPU1 completes the interaction with external devices, the monitoring module notifies CPU2 to continue the unfinished data interaction. Through such a processing mechanism, it can ensure that the relatively important and urgent business data of the user is processed first. And it will not affect the processing of other business data. Specifically, a flag bit can be set in the monitoring module. When the flag bit is low level, CPU1 works, and when the flag bit is high level, CPU2 works.

The technical solution according to the present invention will be further described below with reference to FIG. 8A and FIG. 8B .

Step 802, determine whether the current service requires CPU1 to interact with the external equipment of the terminal. Assume that the current user terminal receives an incoming call. The incoming call belongs to the user's private data, so it is handed over to CPU1 for processing, and it is determined that CPU1 needs to communicate with the audio when processing the incoming call data. Interact with processing devices such as speakers. If the current service does not require the CPU1 to interact with the external device of the terminal, the process ends.

Step 804, judge whether CPU1 is currently connected to the audio processing device, if not connected to the audio processing device (indicating that the audio processing device is currently connected to CPU2), go to step 806, otherwise, end the process.

Step 806, CPU1 sends a pause notification to CPU2, so that CPU2 disconnects from the audio processing device.

Step 808, CPU1 connects with the audio processing device.

Therefore, when CPU2 is processing the non-private data of the player application data and is connected with the audio processing device, if an incoming call is received at this time, the connection between CPU2 and the audio processing device can be interrupted, so that CPU1 can be connected with the audio processing device, Even if the audio processing device is occupied by CPU2, it can receive incoming calls in time.

After the service processing of CPU1 is finished, CPU2 may be notified to continue the unfinished business, for example, to continue playing music. With such a processing mechanism, the business can be carried out in an orderly manner under the coexistence of multiple processors, without affecting the normal use of users, and since multiple processors are used to process different data, it not only improves data processing Speed, but also further strengthened data security.

As shown in FIG. 8B , there is shown a flowchart of processing of the CPU2 with respect to the CPU1 shown in FIG. 8A .

Step 810 , judging whether CPU2 has received a suspension notification from CPU1 , if yes, go to step 812 , otherwise go to step 814 .

Step 812, CPU2 disconnects the connection with the peripheral device, if CPU2 is processing the player application data, disconnects the connection with the audio processing device.

Step 814, judge whether the current business to be processed by CPU2 needs to use peripherals, for example, need to send pictures to another terminal via Bluetooth, if yes, go to step 816, otherwise end the process.

Step 816, CPU2 connects with Bluetooth.

The above step 812 also includes continuing to connect to the audio device and continue playing music when receiving the notification that the CPU1 has completed the business processing.

For another example, when the display screen is displaying video A (CPU2 is connected to the display screen), a video call is received (CPU1 wants to connect to the display screen), in order to ensure that the user can process the video call in time, CPU1 sends to CPU2 Pause the notification, CPU2 interrupts playing the video A, and when it is determined that CPU2 is disconnected from the display screen, CPU1 establishes a connection with the display screen. After the video call ends, CPU1 notifies CPU2 that the video A can continue to be played. After receiving the notification, CPU2 establishes a connection with the display screen and continues to display video A; in this embodiment, only the display screen is taken as an example, but in practical applications, connection switching of peripheral devices such as touch screens and speakers is also involved.

Therefore, when multiple processors all need to be connected to the same peripheral such as screen, camera, speaker, and WIFI, the processor handling new business can control other processors that are processing other business to interrupt the connection with the corresponding external device. When the processing of the new service is finished, the other processor can be notified that it can continue to connect with the corresponding external device to continue the unfinished service.

It should be understood that the processing unit in the foregoing embodiment may be a complete processor, or a core of a multi-core processor.

The technical scheme of the present invention has been described in detail above in conjunction with the accompanying drawings, and a new data processing scheme is proposed, which can screen private data and non-private data from external devices and hand them over to different processors for processing, avoiding It eliminates data confusion, ensures the security of private data in the terminal, and improves user experience.

For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
