Abstract

The invention provides a file reading method, a storage device and an electronic device. The file reading method is applied to an electronic device, and the electronic device includes a non-volatile memory as an internal memory. The method includes: determining that a specific file in the electronic device is a hotspot file according to a predetermined condition; copying the determined hotspot file into the non-volatile memory; and when receiving a request to read the hotspot file , addressing directly to the non-volatile memory, and reading the hotspot file from the non-volatile memory.

Description

technical field [0001] The present invention relates to the field of electronic equipment, and more specifically, the present invention relates to a file reading method, storage equipment and electronic equipment. Background technique [0002] At present, in electronic devices using embedded systems, raw flash (raw flash memory), SDCard (secure digital memory card), mmc (multimedia memory card) and other devices are usually used as external memory, which is a non-volatile memory. For storing data that needs to be stored for a long time. [0003] On the other hand, currently, in electronic devices, the commonly used internal memory is a volatile memory. Data read to the internal memory during operation of the electronic device will be lost after the electronic device is powered off. [0004] Affected by device characteristics, the access rate of external memory is relatively slow. In addition, during the operation of the electronic device, it is often necessary to read a s...
