Background technique

[0002] With the development of the domestic electronic payment market and payment technology, the software system of the payment terminal is also increasingly complicated.

Most of the current payment terminals use a complex operating system based on Linux or even Android, and support a variety of peripheral drivers including IC cards, magnetic cards, RF cards, various communication methods, and implement GUI, device services, management, and more. A variety of software features such as applications.

[0003] After using Linux or Android, due to the huge size of the system, and the addition of many additional payment-related software modules that need to be initialized, the startup speed is very slow, about 20 seconds or even close to one minute. This has caused a lot of change for the customer and has a great impact on the productivity of the production test.

[0004] Currently, the payment terminal of the operating system is used, and the initialization process is mostly performed after the initialization of each software module is completed in order. Even with a multi-core processor, the initialization process is done in a single task. The downtime is slow and the initialization process is long.

[0010] Step S3: sequentially performing initialization of the software module in the corresponding initialization set according to the initialization process

, the software modules are initialized according to the order in the initialization set;

[0011] After the initialization process is completed and the initialization is completed, the payment terminal initialization is completed.

[0012] Preferably, in the foregoing method for improving the startup speed of the payment terminal, the division of the software module in the initialization set satisfies the condition: a, the following software module depends on the initialization of the previous software module; b, an initialization The initialization of any software module in the collection does not depend on the software modules in other initialization sets; c. Two software modules that do not have a sequential relationship with each other must be located in different initialization sets.

[0013] Another technical solution of the present invention is to provide an apparatus for improving the startup speed of a payment terminal, including: [0014] a dividing module, configured to acquire a software module that needs to be initialized in a payment terminal, and divide the software module into multiple Initialization set;

[0015] The software modules in each of the initialization sets are arranged in order; the division of the software modules in the initialization set satisfies the following conditions: Do not put two software modules that are not related in the same initialization set, avoid one Any software module is waiting for another software module to initialize;

[0016] a creating module, configured to sequentially create a corresponding number of initialization processes according to the number of initialization sets in the dividing module;

[0017] The execution module is configured to sequentially perform initialization of the software modules in the corresponding initialization set according to the initialization process, and after the initialization process is performed, the payment terminal initialization is completed.

[0018] Preferably, in the foregoing apparatus for improving the startup speed of the payment terminal, the division of the software module in the initialization set satisfies the following conditions: a, the following software module depends on the initialization of the previous software module; b. The initialization of any software module in the collection does not depend on the software modules in other initialization sets; c. Two software modules that do not have a sequential relationship with each other must be located in different initialization sets.

Advantageous effects of the invention

Beneficial effect [0019] The beneficial effects of the present invention are as follows: Different from the prior art payment terminal initialization process, most of the software modules are initialized and loaded before the program is initialized. The method and device of the present invention modify the initialization program into multi-process initialization. Execution, making full use of the parallel processing capability of multi-core processors, shortening the system initialization time. For single-core processors, this approach also reduces system initialization to a certain extent. Because the processor utilization is improved by parallel operation, it is possible to avoid the 10-consumption type initialization blocking, which causes the other initialization operations to be extended and the downtime is extended. Provides production efficiency of the payment terminal.

detailed description

[0024] The most critical idea of the present invention is that the method and apparatus of the present invention shortens the payment terminal system initialization time by modifying the initialization procedure to the initialization of the multi-process.

[0025] With the development of the ARM Cortex family of processors, the price of multi-core processors has been declining, and payment terminals have begun to use multi-core processors. Currently, the Cortex series of multi-core processors are based on the SMP architecture, Linu

The X kernel can automatically distribute multiple tasks to multiple processor cores and is transparent to both application and kernel drivers.

[0026] While current Linux-based systems, including Android, the initialization process is single-tasking, including initialization in the kernel, and for spatial initialization. This does not take advantage of multi-core processors during the startup phase. Even for a single-core processor, during the initialization of a single task, there is a problem because it waits for the hardware to complete the work (such as reading a file, detecting peripherals) and blocking on an initialization node, and the processor is idle, and it is also started. It has had a certain impact.

[0027] Therefore, based on the above considerations, the system initialization process can be run in a multitasking manner to improve processing. The utilization of the device allows more computing power to be used in the initialization process. Considering that the initialization process in the Linux kernel is too complicated, involving many memory management and task management initialization, it is difficult to implement multitasking. The present invention focuses on improving the parallel capability of user space initialization to improve the startup speed.

[0028] Referring to FIG. 1, the present invention provides a method for improving the startup speed of a payment terminal, including the following steps: [0029] Step S1: acquiring a software module that needs to be initialized in the payment terminal, according to the initialization relationship of each software module, Dividing the software module into a plurality of initialization sets;

[0030] the software modules in each of the initialization sets are arranged in an initialization order; the division of the software modules in the initialization set satisfies the condition that: two software modules that do not have an initialization order dependency are not placed in the same initialization set. Avoiding an arbitrary software module in the payment terminal, waiting for another software module to initialize, wasting waiting time;

[0031] The division satisfies the condition specifically as: a, the following software module depends on the completion of the previous software module initialization; b

The initialization of any software module in an initialization set does not depend on the software modules in other initialization sets; c. Two software modules that do not have a sequential relationship with each other must be located in different initialization sets.

[0032] The above setting avoids waiting for an arbitrary software module in the payment terminal to wait for another software module to initialize, and wastes waiting for the time.

[0033] Step S2: According to the number of initialization sets in step S1, sequentially create a corresponding number of initialization processes.

[0034] Step S3: sequentially performing initialization of the software module in the corresponding initialization set according to the initialization process

[0035] After each initialization process performs the initialization, the payment terminal initialization is completed. Initialize the program for further work

[0036]

[0037] Referring to FIG. 2, the present invention further provides an apparatus 1 for improving a startup speed of a payment terminal, comprising:

[0038] The dividing module 11 is configured to acquire a software module that needs to be initialized in the payment terminal, and divide the software module into multiple initialization sets;

[0039] the software modules in each of the initialization sets are arranged in order; the division of the software modules in the initialization set satisfies the following conditions: Do not put two software modules that are not related in the same initialization set , to avoid an arbitrary software module waiting for another software module to initialize;

[0040] The division of the software module in the initialization set satisfies the condition: a, the following software module depends on the initialization of the previous software module; b, the initialization of any software module in an initialization set does not depend on other initialization sets. Software modules; _c , two software modules that do not have a sequential relationship with each other, must be located in different initialization sets. The above setting avoids waiting for an arbitrary software module in the payment terminal to wait for another software module to initialize, which wastes waiting time.

[0041] The creating module 12 is configured to sequentially create a corresponding number of initialization processes according to the number of initialization sets in the dividing module.

[0042] The execution module 13 is configured to sequentially perform initialization of the software modules in the corresponding initialization set according to the initialization process, and after the initialization process is performed, the payment terminal initialization is completed.

[0043] In summary, the method and apparatus for improving the startup speed of a payment terminal provided by the present invention modify the initialization procedure into multi-process initialization execution, fully utilizing the parallel processing capability of the multi-core processor, and shortening the system initialization period. .

[0044] For a single core processor, the method of the present invention also reduces system initialization to a certain extent. Because the processor utilization is improved by parallel operation, it is possible to avoid the 10 consumption type initialization blocking, which causes the other initialization operations to be extended and the downtime is extended. Improve the production efficiency of the payment terminal.
