Embodiment Construction

[0069] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0070] figure 1 It is an application environment diagram of the data processing method in one embodiment. refer to figure 1 , the data processing method is applied to the data processing system. The data processing system includes a POS terminal 110 and a non-volatile extended memory 120 , and the POS terminal 110 is connected to the non-volatile extended memory 120 . The non-volatile extended memory 120 may be a memory card or a hard disk, and the memory card may specifically be an SD card (Secure Digital Memory Card) or an MMC card (MultiMedia Card). The POS terminal 110 can obtain the origin...

Abstract

Disclosed is a data processing method, comprising: acquiring initial data from a user space and transferring the same to a kernel space (S302); acquiring a currently available memory of an internal storage device in a POS terminal (S304); if the currently available memory is less than a minimum available memory threshold, selecting, from the internal storage device, data from among data unrelated to the current instance of data processing (S305); storing the selected data in a memory partition included in a non-volatile expansion storage device connected to the POS terminal (S306); storing the initial data in the internal storage device (S307); acquiring target data obtained from the initial data stored in the memory partition and processed by an operating system kernel (S308); and storing, via the operating system kernel, the target data in the storage device partition included in the expanded storage device. (S310).

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data processing method, device, system and POS terminal. Background technique [0002] With the rapid development of mobile payment technology, POS (Point of sales) terminal, as the front-end hardware device of the financial payment system, has become an indispensable part of the transaction process. With the diversified development of financial payment systems, POS terminals can support more and more functions, and people rely more and more on completing transactions through POS terminals. [0003] However, since the POS terminal can support more and more functions, more and more resources are required for data processing on the POS terminal, and the storage space that needs to be occupied is also increasing. The traditional POS terminal and the traditional The data processing method of POS terminals can no longer meet the requirements, resulting in low data process...
