Embodiment Construction
[0047] 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. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0048] The present invention provides a kind of preferred embodiment of EMMC read and write control method, as figure 1 As shown, the method includes:
[0049] Step S100, setting a cache area in memory in advance.
[0050] During specific implementation, a cache area is set in the memory in advance to convert the read and write operations on the EMMC into operations on the cache, thereby reducing the number of reads and writes to the EMMC. Specifically, the cache area is a piece of memory; the cache area is used to create cache units, and each cache unit includes temporary addresses and temporary data; for example, please refer to figure 2 , ...

The invention discloses an EMMC read-write control method and system. The method comprises the steps that a buffer region is set in a memory in advance; when an EMMC read-write operation is detected, the read-write operation is controlled to be used for the buffer region; when it is detected that the data size in the buffer region exceeds the storage range or it is detected that a mobile terminal is shut down, data in the buffer region are written into corresponding addresses in an EMMC, and all buffer units in the buffer region are deleted. According to the EMMC read-write control method and system, the buffer region is set in the memory, the EMMC read-write operation is detected, and the read-write operation is used for acting on the buffer region; when the buffer region is full or it is detected that the mobile terminal is shut down, the data in the buffer region are written in the corresponding addresses of the EMMC, and buffers are emptied, so that the EMMC write operation is optimized, the frequency of actually writing data in the EMMC is greatly decreased, and the service life of the EMMC is prolonged.
Description
technical field [0001] The invention relates to the technical field of mobile terminals, in particular to an EMMC read and write control method and control system. Background technique [0002] At present, mobile terminals generally use embedded memory (EmbeddedMultiMediaCard, referred to as EMMC) as the storage chip. However, EMMC has a limit on the number of writes. When the number of writes exceeds the limit, there is a possibility that the EMMC chip will be damaged; when the EMMC chip is damaged In this case, the files saved by the user will be damaged, the system will run abnormally, and even the mobile terminal will become unusable. [0003] In the existing technology, any read and write operations for EMMC are directly oriented to the EMMC chip. In addition, the frequency of users using mobile terminals is high, resulting in that the number of times to write EMMC can reach the limit after one to two years, and the EMMC chip is damaged. , which greatly shortens the se...
