Background
Referring to fig. 1, a conventional microcontroller 1(Micro controller) includes a processing unit 11 and a memory unit 12, and is widely used in various electronic devices; the microcontroller 1 is provided, for example, in a Point Of Sale Terminal (Point Of Sale/POS Terminal) having a Central Processing Unit (CPU) and a card swiping module, and is used to control the card swiping module.
The memory unit 12 of the existing microcontroller 1 provided in the point-of-sale terminal generally stores an application program for financial transactions and for controlling the card-swiping module. Referring to fig. 2, in a conventional embodiment, the starting address 0x800 of the memory unit 12 stores a Boot Loader 21(Boot Loader), and stores a Visa card application 22 for processing Visa financial card billing and a Master card application 23 for processing Master financial card billing in other memory blocks. The processing unit 11 executes the application program by executing the boot program 21 to jump its memory address to the addresses 0x806, 0x808 in the memory unit 12 of the Visa card application program 22 or the Master card application program 23. The Visa card application 22 and the Master card application 23 each have a driver unit capable of controlling the card-swiping module, and the program parts of the driver units for controlling the card-swiping module are the same, so that the memory unit 12 stores two identical program parts for controlling the card-swiping module, which results in waste of memory space and relatively increases the hardware cost of the memory unit 12.
Referring to fig. 3, in another conventional embodiment, the Visa card application 22 and the Master card application 23 are integrated into an integrated program 2 and stored in the starting address 0x800 of the memory unit 12. However, although this method eliminates the setup of the start program 21, at present, the driver units of the Visa card application 22 and the Master card application 23 capable of controlling the card-swiping module are independent in the integrated program 2, i.e. the memory unit 12 still stores two identical program parts for controlling the card-swiping module. In addition, the authentication mechanisms of the Visa card application 22 and the Master card application 23 are different, and if the above program integration manner is adopted, any program code of the integration program 2 is changed in the process of the point-of-sale terminal development, the integration program 2 needs to be provided to the authentication mechanism corresponding to the Visa card application 22 and the authentication mechanism corresponding to the Master card application 23 for authentication, which easily causes delay of the whole development time course.

[ detailed description ] embodiments
Referring to fig. 4, the program configuration method of the microcontroller of the present invention is implemented on a microcontroller 31, and the microcontroller 31 includes a processing unit 312 and a memory unit 311 and is disposed in a point-of-sale terminal 3. The pos terminal 3 includes a central processing unit 35(CPU), a memory module 36, a card swiping module 32, a communication module 33, and a display module 34, in addition to the microcontroller 31. In addition, the card swiping module 32 includes an input interface (not shown), such as a keyboard or a touch screen.
The card swiping module 32 corresponds to a Visa card application and a Master card application related to financial transactions, both of which include a core program portion and a driver unit capable of controlling the card swiping module 32. The program configuration method of the microcontroller according to the invention is described below with respect to the point-of-sale terminal 3 and the two aforementioned application programs.
Referring to fig. 5-8, first, in step 41, as shown in fig. 6 and 7, each driver unit 52, 62 of each application 5, 6 is divided into a program part 521, 621 for controlling the card swiping module and a program part 522, 622 for controlling the card swiping module, where the program part 521, 621 for controlling the card swiping module is the same, and the program part 522, 622 for controlling the card swiping module is different. The program parts 521 and 621 for controlling the card swiping module are used for controlling the hardware action of the card swiping module 32, and the hardware action mode and type are fixed and are not different due to different software implementation, so the program parts 521 and 621 for controlling the card swiping module with the same program content can be divided from the driver units 52 and 62.
In this embodiment, after the user swipes the card through the card swiping module 32, the user needs to input a password string through the input interface of the card swiping module 32, and the program parts 521 and 621 for controlling the card swiping module are used for controlling the card swiping module 32 and obtaining the password string through the input interface. The two program portions 522, 622 that are not used to control the swipe module each contain program content for encrypting the password string because the encryption algorithms implemented by the two are different, and thus the two program portions 522, 622 that are not used to control the swipe module are different.
Next, in step 42, as shown in fig. 6 and 7, each application 5, 6 is divided into a common program module 53, 63 and a non-common program module 54, 64, wherein the common program module 53, 63 is the program part 521, 621 for controlling the card swiping module, the non-common program module 54 of the Visa card application 5 is composed of the core program part 51 of the Visa card application 5 and the program part 522 not for controlling the card swiping module, and the non-common program module 64 of the Master card application 6 is composed of the core program part 61 of the Master card application 6 and the program part 622 not for controlling the card swiping module.
Next, in step 43, as shown in fig. 8, a boot program 7, one of the two common program modules 53, 63, and the two non-common program modules 54, 64 are respectively stored in different memory blocks of the memory unit 311, wherein the boot program 7 is stored in the starting address 0x800 of the memory unit 311 and records the starting addresses 0x812, 0x814 of the memory blocks storing the two non-common program modules 54, 64, the two non-common program modules 54, 64 record the starting address 0x810 of the memory blocks storing the common program modules 53(63), and the common program module 53(63) also records the starting addresses 0x812, 0x814 of the memory blocks storing the two non-common program modules 54, 64, so that the processing unit 312 can execute the non-common program module 54 of the Visa card application 5 or the non-common program module 64 of the Master card application 6 through the boot program 7, when the common program module 53(63) needs to be executed, the common program module 53(63) is executed through the non-common program modules 54 and 64.
For example, the pos terminal 3 is installed in a shop and has a checkout software installed in its memory module 36, and is connected to a remote financial server via its communication module 33 network. The checkout software supports either "Visa card checkout" or "Master card checkout". Referring to fig. 8, when the consumer uses the Visa card to check out in the store, the store clerk operates the check out software to select "Visa card to check out", and then the consumer swipes the card through the swipe module 32 and inputs a password string through the input interface thereof, so that the cpu 35 of the pos terminal 3 triggers the processing unit 11 of the microcontroller 31 to execute the start program 7 and transmits an instruction or a signal indicating to start the Visa card application 5 to the processing unit 11. Then, the processing unit 11 jumps to the address 0x812 according to the starting address 0x812 of the non-common program module 54 of the Visa card application recorded by the boot program 7 in the memory unit 311 to execute the non-common program module 54 of the Visa card application. Then, the processing unit 11 jumps to the address 0x810 according to the common program module 53(63) recorded by the non-common program module 54 of the Visa card application at the starting address 0x810 of the memory unit 311 to execute the common program module 53(63) to control the card swiping module 32 and obtain the Visa card information of the customer and the inputted password string through the card swiping module 32. Then, the processing unit 11 jumps to the address 0x812 according to the non-common program module 54 of the Visa card application recorded by the common program module 53(63) at the starting address 0x812 of the memory unit 311 to execute the non-common program module 54 of the Visa card application, so as to encrypt the password string, and further transmit the encrypted password and the Visa card information to the financial server for authentication through the communication module 33. Then, the financial server transmits a corresponding verification result to the pos terminal 3 and displays it on the display module 34, for example, a message indicating that the card swiping was successful or failed.
In particular, by the above-mentioned program configuration method of the microcontroller according to the present invention, only one of the two common program modules 53 and 63 is stored in the memory unit 311, which saves the memory space required for storing one common program module 53 and 63 compared to the conventional program configuration method shown in fig. 2, and the Visa card application 5 or the Master card application 6 can be independently provided to the corresponding certification authority for certification during the development process of the pos terminal 3, thereby avoiding the delay of the development process. The above-described method of program allocation of the microcontroller according to the invention also saves memory space compared to the conventional method of program allocation shown in fig. 3, since in general the memory space required for storing the common program module 53, 63 is much larger than the memory space required for storing the start-up program 7.
In another embodiment, the boot program may not be provided in the memory unit 311. For example, referring to fig. 9, the non-common program module 54 of the Visa card application 5 can be stored in the starting address 0x800 of the memory unit 311, and the boot program is integrated into the non-common program module 54 so that the non-common program module 54 has the functions of the boot program, and thus, other applications stored in the memory unit 311 can be executed through the non-common program module 54.
Furthermore, it should be noted that although only the configuration of the plurality of applications corresponding to the card-swiping module 32 in the memory unit 311 of the microcontroller 31 is described herein, it is obvious that the above method can be applied to any hardware module corresponding to a plurality of applications, as long as the applications have the same program portion for controlling the hardware module.
In summary, the program allocation method of the microcontroller according to the present invention divides each application program related to the card swiping module of the pos terminal and the financial transaction into a common program module and a non-common program module for controlling the card swiping module, and stores one of the common program modules and the non-common program modules in different memory blocks of the memory unit of the microcontroller, so that the hardware cost of the memory unit of the microcontroller can be reduced while the application programs are independently installed, thereby achieving the object of the present invention.
The detailed description and examples of the present invention are given above with reference to the accompanying drawings, but the scope of the present invention is not limited thereto, and the equivalent modifications and variations within the scope of the claims of the present invention should be considered as falling within the scope of the present invention.
