Embodiment Construction

[0042] In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] eMMC (Embedded Multi Media Card, embedded multimedia card) adopts a unified MMC standard interface, and packages high-density NAND Flash (flash memory) and MMC in a BGA chip, which is often used in mobile smart terminals such as mobile phones.

[0044] Such as figure 1 As shown, a method for determining eMMC address mapping management according to the characteristics of stored data, the terminal is normally powered on and used, and the method includes the following steps:

[0045] S10. Determine the eMMC partition data address mapping method and the storage location of the mapping ta...

Abstract

The invention provides a method and device for determining eMMC address mapping management according to storage data characteristics. The method comprises the steps: determining an eMMC partition dataaddress mapping mode and a mapping table storage position according to the data characteristics; and dynamically counting and detecting eMMC partition data, and adjusting the partition address mapping mode and the storage position of the mapping table in real time. In conclusion, the eMMC address mapping management is determined according to the characteristics of the eMMC storage data, and the occupation consumption of the eMMC by the mapping table can be reduced, and the data read-write performance can also be improved, and the user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of electronic storage, and in particular relates to a method and a device for determining eMMC address mapping management according to characteristics of stored data. Background technique [0002] eMMC (Embedded Multi Media Card, embedded multimedia card) adopts a unified MMC standard interface, and packages high-density NAND Flash (flash memory) and MMC in a BGA chip, which is often used in mobile smart terminals such as mobile phones. eMMC integrates Nand Flash (flash memory), and naturally there will be logical address and physical address mapping management, wear leveling, garbage collection, bad block management, etc. FTL (Flash Translation Layer) storage translation layer technology implementation. [0003] However, in the mobile phone solution, the data stored in the eMMC always has some special properties, and the static and general FTL management technology is inappropriate and inefficient for the u...
