Terminal, application data processing method, data processing device, and storage medium

Abstract

The invention discloses a terminal, an application data processing method, a data processing device and a storage medium. The terminal comprises a memory, a non-volatile memory NVM buffer, an exchangepartition, a memory controller MMU and an I/O controller. The memory includes a plurality of memory pages, the NVM cache includes a plurality of cache pages, and the swap partition includes a plurality of page slots. The MMU is used for controlling the application data of the memory page and/or the application data of the buffer page to be transmitted between the memory and the NVM buffer throughthe memory bus. The I/O controller is configured to control application data of a page slot and/or application data of a cache page to be transmitted between the switching partition and the NVM cachethrough an I/O bus. The method provided by the embodiment of the invention improves the data exchanging speed in the memory, reduces the response time of the application program, prolongs the life ofthe exchanging partition, and reduces the page jitter caused by the application data frequently moving in the memory page and the page slot in the prior art.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a terminal, a processing method for application data, a data processing device, and a storage medium. Background technique [0002] With the development of mobile microprocessors and mobile operating systems, mobile devices (such as smart phones, tablets, etc.) are becoming more and more popular, and application functions designed for mobile devices are becoming more and more abundant. On the one hand, these feature-rich applications can help improve the user experience of mobile devices, but on the other hand, they require more memory resources and storage resources. In order to improve the user experience in the Android operating system, when the user starts an application program, even if the user exits the application program, the program does not really exit, and still resides in the memory. When the user opens the application program again, the applicati...

Problems solved by technology

[0006] Although the Swap partition based on block devices can solve problems such as insufficient memory, the I / O device still has problems such as slow speed and large delay, and the swapping in and out of data in the page needs to go through I / O, and the data transmission needs to be done by the device. The driver is responsible and needs to perform I / O scheduling, which reduces the performance of the application and affects the user experience

In addition, the flash memory device used as the swap partition in the mobile device has a limited number of erases and writes. Frequent page swapping in / out will lead to premature damage to the flash memory device, and frequent movement of data in the memory and swap partitions will cause page thrashing , adding additional overhead to the system
