Problems solved by technology

Note that since a big limitation of flash memory is the lifetime, for example, the number of writes to the memory bank is limited, and the page-out mechanism requires a lot of space in the memory, the page-out mechanism will damage the memory Durability, which leads to the rapid failure of flash memory
Also, in particular, once the memory bank is full, the page eviction mechanism will jeopardize the performance of the system
When the pages in the storage are moved out of the partition and the partition is full, the system performance will drop significantly

Embodiment Construction

[0019] figure 1 A memory management system showing a page eviction mechanism according to an embodiment of the present invention. The memory management system 100 of the page removal mechanism according to the embodiment of the present invention can be applied to an electronic device, such as a personal digital assistant (PDA), a smart phone, a mobile phone, a mobile Internet device (MID), a small notebook and a global positioning system (GPS) devices or other mobile devices such as handheld devices.

[0020] The memory management system 100 of the page removal mechanism includes a memory 110 , a storage unit 120 , and a processing unit 130 . The memory 110 can record relevant program codes and / or data corresponding to programs / applications executed on a system of the electronic device. The storage unit 120 includes a page-out partition 121 for recording data that is removed from the memory 110 by the page-out mechanism, usually stored in pages. Note that an operating syste...

Abstract

Memory management methods and systems for page-out mechanism are provided. A page-out mechanism is performed via an OS (Operating System) based on a parameter of the page-out mechanism, wherein the page-out mechanism moves data from a memory to a storage unit. A usage of a page-out partition in the storage unit is monitored. The parameter of the page-out mechanism is dynamically set according to the usage of the page-out partition, wherein when the usage is increased, the parameter of the page-out mechanism is decreased, and when the usage is decreased, the parameter of the page-out mechanism is increased.

Description

technical field [0001] The present invention relates to a memory management method and system, and in particular to a memory management method and system capable of controlling the performance tolerance of a page-out mechanism. Background technique [0002] In recent years, portable devices, such as handheld devices, have become more sophisticated and more functional. For example, a handheld device may have telecommunication capabilities, e-mail, advanced address book management, media playback, and various other capabilities and applications. Due to the convenience of these devices, these devices have also become one of people's daily necessities. [0003] More and more applications are becoming richer and the number of applications distributed on mobile devices has grown significantly, however, mobile devices are generally equipped with limited physical memory and there is a high chance of encountering OOM (out of memory) situation, and needs to be handled very carefully...
