Embodiment Construction

[0034] refer to figure 1 , the present invention proposes a first embodiment, which provides a fast data reading method, which can increase the reading speed of electronic device memory data.

[0035] The electronic device in this embodiment includes a memory, a non-volatile memory, and a system. Wherein, the non-volatile memory is serial flash memory, that is, serial FLASH.

[0036] The fast data reading method comprises the steps of:

[0037] S10, establishing a cache space in the memory;

[0038] S11, recording the number of read times of data in the memory;

[0039] S12, storing the memory data with the most read times in the cache space;

[0040] S13, receiving a command to read memory data, and updating the number of read times of the data;

[0041] S14, judging whether the data is data in the buffer space; if yes, proceed to step S15; if not, proceed to step S16;

[0042] S15, read from the cache space;

[0043] S16, read from the memory, and update the data in t...

Abstract

The invention discloses a method for fast reading data and a device thereof. The method is applied to an electric device comprising a memory and a non-volatile memory, which includes steps of creating a cache space in the memory, recording the reading frequency of data in the memory, storing the memory data with highest reading frequency in the cache space, receiving the order of reading the memory data and updating the reading frequency of the data, further, judging whether the data is the data in the cache space or not, if so, then reading the data from the cache space, if not, then reading the data from the memory, and updating the data in the cache space according to the reading frequency of he memory data, or storing the data in the cache space. The device for fast reading data stores the memory data with highest using frequency in the cache space according to reading frequency, which enables the electric device to call the memory data for use from the cache space, thereby increasing reading speed of the memory data.

Description

technical field [0001] The invention relates to electronic data processing technology, in particular to a method and device for fast data reading. Background technique [0002] With the increasingly fierce competition in the set-top box market, various set-top box manufacturers have put cost competition on the agenda. Using low-cost chips is an effective way to reduce the cost of set-top boxes. The memory of the low-cost chip is small, and serial flash memory (Flash) is adopted, so that the memory does not have enough space to store the data resources (picture data or font data, etc.) that the set-top box needs to display, and the data resources can only be It is stored in the serial flash memory, but the data reading speed of the serial flash memory is slow, which affects the interface display effect of the set-top box. Contents of the invention [0003] One of the objectives of the present invention is to provide a fast data reading method and device to increase the dat...
