[0003] With the development of Internet technology and the popularization of smart phones, more and more business can be conducted through corresponding applications on smart phones, bringing great convenience to people's lives.

[0004] For business areas such as payment, QR codes are now widely used. However, in actual applications, for some users or in some scenarios, payment based on QR codes also requires relatively cumbersome operations. With the increase in mobile terminals with near-field communication (NFC) functions, especially smart phones, many smart phones support payment methods based on near-field communication. Specifically, the smart phone remains in card simulation mode and simulates itself as an NFC card for reading by NFC machines for payment. Alternatively, the smart phone remains in card reader mode and monitors whether there are NFC machines or NFC cards for payment nearby.

[0005] In addition to the popularity of smartphones, there are also more and more smart wearable devices, mainly smart watches. In order to enable smart watches to support payment, some payment service providers directly use the payment solutions on smartphones on smart watches.

[0006] However, smart watches have differences and limitations in terms of energy consumption, screen size, etc. compared to smartphones. Based on this, a payment solution that is more suitable for smart watches is needed. Summary of the invention

[0046] The embodiments of this specification provide a method, apparatus, device and storage medium for processing NFC services of a smart wearable device.

[0047] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0048] The smart wearable devices mentioned in this application are mainly typified by smart watches. Of course, they can also be other devices such as smart bracelets and smart rings. Compared with smart phones, smart wearable devices usually have significantly smaller screens or no screens at all, and their power and processing power are often lower. Therefore, they are more sensitive to energy consumption and computing burden. This application is designed to create solutions for such actual situations. Not only that, it is also especially targeted at children's smart watches, which are suitable for the situation where the users are minors such as children, and the solutions have been further polished and improved.

[0049] As mentioned in the background technology, currently, the payment scheme on the smart phone is mainly used directly on the smart watch. Taking the payment service based on QR code as an example, the payment code can be generated on the smart watch, and the merchant scans the code through the code scanning device. After scanning the code, the merchant backend initiates the payment. However, assuming that the merchant does not have a code scanning device, it may be difficult to use the smart watch for QR code-based payment; for smart phones, since the smart phone can scan the merchant's code, the merchant's lack of a code scanning device will not hinder the payment of the smart phone. Smart watches will have unique problems because they do not have a code scanning function or are not convenient for code scanning operations. Taking the NFC-based payment service as an example, for user mobile terminals, most of them adopt the card simulation working mode. However, this method is subject to great restrictions by mobile phone manufacturers and is not flexible enough. The applicant considers transplanting the solution of actively adopting the card reader working mode used on his smartphone to the smart watch. This solution is to keep the NFC card reader on the smartphone open. When there is an NFC card or simulated card approaching, the information in the card can be read through NFC, and then the corresponding application on the smartphone can be called up to execute the corresponding service according to the information content. However, when actually tested on the smart watch, the energy consumption is high, which will affect the battery life of the smart watch. Therefore, consider creating a payment solution based on near-field communication that is more suitable for smart watches.

[0050] Based on this overall situation, the solution of the present application will be further described below.

[0051] Figure 1 A flowchart of a method for processing NFC services on a smart wearable device provided for one or more embodiments of this specification. The execution subject of the process may include a smart wearable device, and the software level may specifically involve the operating system of the smart wearable device, and the designated service applications on the smart wearable device, such as payment applications, instant messaging applications, etc. For ease of description, some embodiments mainly take a smart wearable device such as a smart watch as an example for explanation, and the smart wearable device supports the NFC function, has an NFC card reader, and may have a screen or may not have a screen.

[0052] Figure 1 The process in includes the following steps:

[0053] S102: Control the NFC card reader on the smart wearable device to be in a closed state.

[0054] In one or more embodiments of the present specification, the NFC card reader on the smart wearable device is turned off by default. In the turned off state, it will not actively attempt to perform NFC card reading operations, and will not actively monitor whether there are NFC sensing objects approaching the surrounding area, which can effectively reduce the energy consumption of the smart wearable device.

[0055] S104: In the closed state, receiving an NFC service trigger instruction for the smart wearable device.

[0056] When the user needs to use the NFC function of the smart wearable device, the user triggers the NFC function in a predetermined convenient triggering manner so that the smart wearable device receives the NFC service triggering instruction.

[0057] For example, after the screen of the smart wearable device is turned on, the NFC service shortcut entry is displayed. The NFC service shortcut entry is generated according to the NFC service non-quick access path of the specified business application, and is used to quickly enter the NFC card reader mode page of the specified business application; in response to the user's access operation to the NFC service shortcut entry (for example, the user can click on the NFC service shortcut entry; or based on gesture implementation, etc.), the corresponding generated NFC service trigger instruction for the smart wearable device is received. The NFC service shortcut entry can be displayed in a place that is easy to view or easy to access, such as directly on the desktop of the smart wearable device or a sub-desktop (for example, if there is a sub-desktop, the desktop can be switched by flipping up and down or flipping left and right). Of course, users can also trigger the NFC service through the above-mentioned NFC service non-quick access path, so the operation will be more cumbersome.

[0058] In one or more embodiments of the present specification, the NFC service trigger instruction is not simply used to trigger the NFC reader. It corresponds to a specified service application and can accurately trigger the NFC reader first. In this way, the subsequent state of the NFC reader can be controlled by the specified service application (for example, the NFC reader can be switched back to the off state in time after the service is completed) without affecting other applications, which also helps to accurately control energy consumption.

[0059] S106: In response to the NFC service triggering instruction, enter a designated service application on the smart wearable device, and automatically switch the NFC card reader from the closed state to the open state through the designated service application.

[0060] In the solution previously attempted by the applicant, the NFC reader is in a dominant position, and in the default open state, it triggers the corresponding application according to the information read. However, in the solution of the present application, the designated business application is in a dominant position instead, and the state of the NFC reader can be controlled by the designated business application and used as needed.

[0061] After receiving the NFC service trigger instruction, if the designated service application has not been started, it will be automatically started and placed in the foreground. If the designated service application has been started before, it will be kept in the foreground to execute the target service. Not only can the designated service application be entered, but also the NFC service page in the designated service application (such as the above-mentioned NFC card reader mode page, etc.) can be directly reached. On this page, more information can be prompted to the user, such as what service the page corresponds to, what to do next, etc.

[0062] In order to improve security, you can also set up additional instant verification methods such as passwords or biometrics. If the verification is passed, the trigger can be realized normally. Otherwise, you can deny access to the specified business application and deny operation of the NFC card reader.

[0063] S108: After the smart wearable device is close to a target NFC device, target business information is read from the target NFC device through the NFC card reader in the open state, so that the designated business application obtains the target business information.

[0064] After the NFC card reader is switched to the on state through active triggering, if the distance between the smart wearable device and the target NFC device is sufficient for NFC communication, the NFC card reader can read the target business information. For example, in the payment business scenario, payment information can be read; in the social scenario, business card information can be read; and so on.

[0065] S110: Execute a corresponding target service according to the target service information through the designated service application.

[0066] In one or more embodiments of this specification, if the execution of the target service requires the participation of the server, the target service can be completed by interacting with the server according to the target service information through the designated service application, for example, paying the payment amount indicated in the target service information. In this case, the smart wearable device needs to be online, and the designated service application mainly communicates with the server in real time to complete the target service. The target NFC device can obtain the service execution result from the server.

[0067] After the designated business application obtains enough information indirectly from the target NFC device through the NFC reader, it can be considered that the NFC reader has completed its task this time, and the NFC reader can be switched back to the off state in time to minimize energy consumption.

[0068] pass Figure 1The method avoids the use of QR codes to execute some target businesses such as payment, thereby avoiding the problem that users who want to use smart wearable devices to perform target businesses cannot execute the target businesses as expected when facing merchants without QR code scanning and payment devices; in particular, the NFC card reader on the smart wearable device is actively controlled to be in a closed state by default, rather than being kept in an open state like the NFC card reader on the smartphone. When it is needed, it will quickly trigger the NFC card reader to be automatically switched to an open state through a specified business application to complete the target business. In this way, for the specified business application, it has better pertinence and controllability, better security, and is very friendly to smart wearable devices that are very sensitive to resources and power consumption. Therefore, such a solution is more suitable for smart wearable devices including smart watches.

[0069] based on Figure 1 This specification also provides some specific implementation plans and extension plans of the method, which will be described below.

[0070] In one or more embodiments of this specification, although the shortcut icon can be used as a quick entry for the NFC service and accessed by clicking, the operation is still not smooth enough. Based on this, the present application further provides a smoother triggering solution to trigger the NFC service.

[0071] Under this scheme, the screen of the smart wearable device can be triggered by the user through the first gesture, and the NFC service shortcut entry prompts the second gesture. The first gesture and the second gesture are not click operations, and may not be biometric verification operations. Therefore, in this case, the NFC service shortcut entry may not be used for click entry, and the user only needs to check the NFC service shortcut entry. The first gesture is, for example, a gesture of raising the hand to look at the watch, and the second gesture is, for example, a gesture of further changing the direction of the hand (for example, a gesture of sending the hand forward, another example, a gesture of quickly waving the hand horizontally, etc.). For example, the user can raise the hand to look at the smart watch, triggering the dial to light up the screen, and then see what the second gesture is through the displayed NFC service shortcut entry. Assuming that it is a gesture of sending the hand forward, the hand can be sent forward to the target NFC device in front of it, thereby triggering the NFC service. It can be seen that this operation process is very smooth, and redundant operations are minimized as much as possible. The user experience is good, and energy saving, security requirements and convenience requirements are taken into account.

[0072] Furthermore, in order to reduce the probability of misoperation, a second gesture that may be different may be dynamically adopted each time. In this case, the user may need to look at the NFC service shortcut entrance displayed on the bright screen each time.

[0073] Similarly, the above solution based on the coordination of the first gesture and the second gesture can also be used for smart wearable devices without screens. In this case, for example, a fixed first gesture and a second gesture can be used (for example, allowing the user to pre-set them), or a dynamic second gesture can be used based on voice prompts, and so on.

[0074] In one or more embodiments of this specification, in order to facilitate users to grasp the real-time situation, the control status of the NFC card reader can also be explicitly displayed to guide and constrain the user to a certain extent, which helps to improve security and also helps to ensure that the control of energy consumption reaches the expected level. Based on this idea, a NFC card reader control coordination solution on a smart wearable device is provided. Figure 2 A schematic diagram of the process of the scheme is shown.

[0075] Figure 2 The process in includes the following steps:

[0076] S202: After switching the NFC card reader from the closed state to the open state, displaying progress change prompt information corresponding to the open state on the smart wearable device.

[0077] In one or more embodiments of the present specification, the progress change prompt information may include: countdown information, and / or the progress information of the detected target business. In the case of countdown information, after switching to the on state, a countdown task can be established and executed, and the user can be prompted on the interface with the remaining operation time, or the remaining available time of the NFC reader this time; for the user, this method is more mandatory. In the case of the progress information of the detected target business, one or more landmark stage points in the execution process of the target business can be used to display the stage points before which the NFC reader is still needed, and can also prompt what specific work the NFC reader is involved in at these stage points; for the user, this method is clearer and more transparent, especially suitable for user groups such as minors or the elderly.

[0078] S204: If it is determined that the corresponding progress is finished according to the progress change prompt information, the designated service application is placed in the background or closed, or the NFC card reader is switched back to the closed state.

[0079] In order to prevent the NFC card reader from being in the open state unnecessarily, based on progress monitoring (for example, determining when the countdown ends; for example, determining when the landmark stage point after the NFC card reader is used is reached; etc.), the designated business application can be automatically deactivated as soon as possible. In particular, the NFC card reader can be automatically switched back to the closed state in a timely manner to prevent resource monopoly and increased energy consumption.

[0080] In practical applications, since many minors, especially children, are usually restricted from using smartphones by their parents or schools, this group tends to use children's smart watches as a substitute to a certain extent. In this case, the above-mentioned smart wearable device can specifically be a children's smart watch. This application focuses on the particularity of this case and further improves the above basic solution.

[0081] The applicant mainly summarized the problems caused by two special features in this case. First, the adaptability of children's smart watches is not as good as that of adult smart watches. Therefore, there may be fewer NFC devices that can better support it, or even if it is supported, the business is restricted and cannot be used normally; second, because the users of children's smart watches are minors or even very young children, the safety and behavioral effectiveness are tested.

[0082] In response to the first aspect of the problem, the present application considers enabling children's smart watches to obtain the ability to determine the applicable NFC devices in the surrounding area. However, in actual applications, the children's smart watches themselves have limited capabilities and are difficult to achieve, and there are hidden dangers in terms of security. In order to solve this problem, the present application provides a solution for parents' mobile terminals to assist in interacting with children's smart watches. Figure 3 A schematic diagram of the process of the scheme is shown.

[0083] Figure 3 The process in includes the following steps:

[0084] S302: The children's smart watch as the smart wearable device interacts with the parent's mobile terminal, so that the parent's mobile terminal determines one or more nearby NFC devices suitable for the children's smart watch.

[0085] The parent mobile terminal is held by the parent of the user of the children's smart watch. The children's smart watch can, for example, display an interactive QR code, and the parent's mobile terminal scans it, triggering the parent's mobile terminal to query the nearby NFC equipment suitable for the children's smart watch for the children's smart watch. The interactive QR code can be used to determine the model or capabilities of the children's smart watch. There can also be multiple optional interactive QR codes, corresponding to different functions or services. One is selected on the children's smart watch and provided to the parent's mobile terminal for more detailed query and screening of applicable NFC equipment through such functional or business dimensions.

[0086] The solution in the previous paragraph is more suitable for scenarios where parents are near their children, and can even support scenarios where children's smart watches are running offline. If parents and children are not in the same place, they can interact through remote communication and send relevant information from the children's smart watches to the parents' mobile terminals for query.

[0087] The parent's mobile terminal can be a smart phone, tablet computer, or car computer with a larger and better screen and capabilities than the child's smart watch, so that it can query and display one or more NFC devices suitable for the child's smart watch. Of course, if the capabilities are strong enough, the parent's mobile terminal can also be an adult's smart watch or other device.

[0088] S304: When interacting with the parent mobile terminal, sharing the location of the children's smart watch with the parent mobile terminal.

[0089] Assuming that the parent is near the child, the location sharing operation may not be performed, and the location of the parent's mobile terminal may be used directly, so that the location information does not need to be unnecessarily exposed from the child's smart watch. If location sharing is performed, for example, the location may be included in the above-mentioned interactive QR code.

[0090] S306: Receive the navigation route from the child's smart watch to the target NFC device and the authorization information for the target NFC device sent by the parent's mobile terminal, so as to perform business interaction with the target NFC device according to the authorization information; wherein the target NFC device is selected from the one or more NFC devices, and the navigation route is generated according to the location.

[0091] After the parent's mobile terminal searches and determines the applicable NFC equipment, there are multiple usage plans. For example, the parent can directly show these NFC equipment to the child on the parent's mobile terminal. The plan in steps S306 to S312 is a more comprehensive plan.

[0092] In one or more embodiments of this specification, the target NFC device is selected by the parents, and the authorization information is set by the parents precisely for the target NFC device, rather than generally for the children's smart watch. In this way, the risk of the business that the child can perform on the target NFC device can be accurately and more timely controlled. That is, the parents can accurately authorize the business object for the child, avoiding the child's abuse of the children's smart watch and NFC device to conduct business, and ensuring the parents' high instant control, which helps to improve security and also helps to prevent the target NFC device from doing evil.

[0093] S308: After the interaction with the parent's mobile terminal, it is determined that the child's smart watch has arrived near the target NFC device, and a service interaction is performed with the target NFC device.

[0094] S310: Acquire the service restriction information set by the parent mobile terminal for the target NFC device, where the service restriction information includes service type restriction information and / or service transaction amount restriction information.

[0095] The service restriction information may be included in the authorization information or may be set independently. In the latter case, the authorization information may not be required, and parents may only use the service restriction information to perform light control.

[0096] S312: Determine whether the service interaction exceeds the limit corresponding to the service restriction information; if so, block the service interaction.

[0097] It should be noted that in the above exemplary solution, based on the authorization information and / or business restriction information, the risk is blocked as much as possible from the source (i.e., the NFC device). This method can be implemented in cooperation with the server corresponding to the NFC device (which also belongs to the server corresponding to the children's smart watch). In this way, the judgment of the restriction can also be performed by the server, which can reduce the burden on the children's smart watch. In this case, parents can report the authorization information and / or business restriction information to the server, and not necessarily to the children's smart watch. The server will supervise and control the subsequent business behavior of the target NFC device. In this way, the burden on the children's smart watch will be further reduced, and the children themselves do not need to care about these behind-the-scenes actions to ensure the security of their own equipment and business.

[0098] Furthermore, in order to prevent children from abusing the NFC service of children's smart watches and causing losses, one or more embodiments of this specification also provide a flowchart of an auxiliary solution for revoking the NFC service of children's smart watches, see Figure 4 .

[0099] Figure 4 The process in includes the following steps:

[0100] S402: After interacting with the parent's mobile terminal, the children's smart watch determines that it has arrived near the target NFC device and performs business interaction with the target NFC device.

[0101] S404: During the business interaction process, one or more predetermined sensors are used to collect evidence of transactions involving minors, and corresponding evidence collection information with privacy protection is generated.

[0102] Automatically collect transaction evidence before or during business interaction. It should be noted that the evidence collected by underage transaction evidence here is mainly to prove that the transaction person is a minor, not for identity verification. Audio, video or other sensors can be used for corresponding evidence collection.

[0103] Here, considering that children's smart watches may not have cameras, or the camera capabilities are not high enough, or the camera is not convenient to use. Therefore, a preferred solution for evidence collection based mainly on audio is further provided, and of course, image evidence collection can also be combined. However, it should be noted that the audio evidence collection here is not just a simple automatic recording, but also includes active guiding conversations, so as to ensure both friendliness to minors and sufficient effectiveness of evidence collection.

[0104] Under this solution, for example, a dialogue model for guiding evidence collection for minors is pre-trained. Here, special attention is paid to learning the way minors speak and the logical chain information of the rigor of the required evidence. According to the requirements of these two dimensions, the trained dialogue model for guiding evidence collection is used to instantly generate voice dialogues. Through children's smart watches, the dialogues are played in a timely manner before or during business interactions to guide the current minors to conduct question-and-answer dialogues, so as to make it clear that minors are indeed trading, as well as some required background information details (for example, whether there are parents around, whether they want to buy, whether there are merchants who are inducing them, etc.). The content of the automatically recorded voice dialogue is used as evidence information, or it can be further refined and then used as evidence information. Of course, the privacy of evidence information can also be protected through secure computing, encryption, or obfuscation to avoid exposing the privacy of minors and prevent the evidence information from being tampered with.

[0105] S406: Report the evidence information to the parent's mobile terminal, so that the server obtains the evidence information through the child's smart watch or the parent's mobile terminal, and associates it with the business information corresponding to the business interaction for responding to the business cancellation request.

[0106] After conducting business through children's smart watches, if parents feel that it is inappropriate or even involves deception (for example, merchants induce minors to spend money to recharge, etc.), they can initiate a corresponding business cancellation request to the server. The business cancellation request will be associated with the responsive evidence information. Thus, the server can more intelligently analyze and decide whether to allow the cancellation of the corresponding business based on the evidence information. This way, fairness and efficiency are better, which helps to avoid liability disputes between merchants and users and can truly protect the interests of the reasonable party.

[0107] According to the above description, in order to understand the main idea of ​​the present application in a typical and concise manner, one or more embodiments of this specification provide an application scenario in which: Figure 1 A schematic diagram of an embodiment of the method of Figure 5 .

[0108] In this application scenario, the subject of "watch payment" in the figure can specifically be a watch payment application, as the above-mentioned designated business application, and the subject of "wearable device" can specifically be a smart watch, especially a children's smart watch, as the above-mentioned smart wearable device, and the NFC machine is owned by the merchant.

[0109] An NFC shortcut is pre-customized on at least one desktop of the smart watch (as the above-mentioned NFC shortcut entry. Of course, in addition to this shortcut for touch screen clicking, other forms of shortcut entries can also be used; for example, the specified operation method of a physical control such as a knob on the watch is customized as an NFC shortcut entry; for another example, the user's specified expression is used as the NFC shortcut entry, and when the user verifies that the specified expression is passed, it directly triggers automatic quick entry), which is used to quickly enter the NFC reader mode page, which is a page in the watch payment application.

[0110] exist Figure 5 In the process, the NFC card reader of the smart watch is turned off by default; the user clicks the NFC shortcut on the smart watch to trigger the opening of the watch payment app and directly enter the NFC card reader mode page in the watch payment app; the NFC card reader of the smart watch is automatically turned on by the watch payment app, making it temporarily on; thereafter, the user can place the smart watch close to the merchant's NFC machine, so that the NFC card reader reads the payment information from the NFC machine and returns it to the watch payment app; the watch payment app interacts with the server based on the payment information to promote the payment until the payment is completed.

[0111] After turning on the NFC card reader, a countdown can be displayed. After the countdown ends, the watch payment app can be placed in the background or even closed, and the NFC card reader can be automatically switched back to the off state.

[0112] Intuitively, one or more embodiments of this specification also provide a schematic diagram of user-oriented content related to a children's smart watch, see Figure 6(a) to Figure 6(c) .

[0113] Figure 6(a) is a schematic diagram of the content of a desktop on the watch face. The main focus is on the middle area, which has four quick entrances. Among them, the "touch" quick entrance is the above-mentioned NFC service quick entrance. The user can click "touch" to trigger the NFC card reader mode page of the payment application and automatically open the NFC card reader.

[0114] The left picture of Figure 6(b) is a schematic diagram of the NFC reader mode page entered after triggering the "touch and go" function. At this time, the children's smart watch is placed close to the NFC device (a blue aperture is used as an example to prompt the sensing area of ​​the NFC device so that the user can touch it accurately). At the same time, a 10-second countdown is displayed in the upper right corner. When the countdown is over, the page can be automatically exited and the NFC reader can be turned off. There is a "Find the small blue ring" link prompt below. The "small blue ring" here represents the NFC device suitable for children's smart watches.

[0115] The right picture of Figure 6(b) is a schematic diagram of the QR code displayed after triggering the "Find the Little Blue Ring" function. At this time, parents can use their smart phones to scan the QR code to query nearby NFC devices suitable for children's smart watches.

[0116] Figure 6(c) is a schematic diagram of some nearby NFC devices that are queried after the parent's smartphone scans the code. Some privacy information is blocked, but it does not affect the understanding of the solution. It can be seen that in this page, you can further select a certain NFC device (represented by the corresponding merchant) and navigate to it conveniently.

[0160] In the 1990s, improvements to a technology could be clearly distinguished as hardware improvements (for example, improvements to the circuit structure of diodes, transistors, switches, etc.) or software improvements (improvements to the method flow). However, with the development of technology, many improvements to the method flow today can be regarded as direct improvements to the hardware circuit structure. Designers almost always obtain the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that an improvement in a method flow cannot be implemented using a hardware entity module. For example, a programmable logic device (PLD) (such as a field programmable gate array (FPGA)) is such an integrated circuit whose logical function is determined by the user's programming of the device. Designers can "integrate" a digital system on a PLD by programming it themselves, without having to ask a chip manufacturer to design and produce a dedicated integrated circuit chip. Moreover, nowadays, instead of manually making integrated circuit chips, this kind of programming is mostly implemented by "logic compiler" software, which is similar to the software compiler used when developing and writing programs, and the original code before compilation must also be written in a specific programming language, which is called hardware description language (HDL). There is not only one HDL, but many kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. The most commonly used ones are VHDL (Very-High-Speed ​​Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also know that it is only necessary to program the method flow slightly in the above-mentioned hardware description languages ​​and program it into the integrated circuit, and then it is easy to obtain the hardware circuit that implements the logic method flow.

[0161] The controller can be implemented in any appropriate manner, for example, the controller can take the form of a microprocessor or processor and a computer-readable medium storing a computer-readable program code (such as software or firmware) that can be executed by the (micro)processor, a logic gate, a switch, an application-specific integrated circuit (ASIC), a programmable logic controller, and an embedded microcontroller. Examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320. The memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art also know that in addition to implementing the controller in a purely computer-readable program code manner, the controller can be implemented in the form of a logic gate, a switch, an application-specific integrated circuit, a programmable logic controller, and an embedded microcontroller by logically programming the method steps. Therefore, this controller can be considered as a hardware component, and the devices included therein for implementing various functions can also be regarded as structures within the hardware component. Or even, the devices for implementing various functions can be regarded as both software modules for implementing the method and structures within the hardware component.
