Referring to fig. 1, a first embodiment of the present invention is:
the invention provides a method for accelerating PNG display speed based on small memory embedded equipment, which comprises the following steps:
s1, when the small memory embedded device is powered on, all PNG pictures are preloaded to obtain palette data and compressed picture pixel data corresponding to all PNG pictures, and the palette data and the compressed picture pixel data are stored;

The obtained picture pixel data is compressed, the data volume is greatly reduced, and the cache corresponding to the picture pixel data in the memory is released, namely only the palette data occupying a small memory is reserved, so that the method is suitable for small-memory embedded equipment.
In the loading process, the ordered loading may be performed according to a preset priority order, for example, the priority of the main page in the interface is the highest, the priority of each secondary page in the main page is reduced once, the priority of the sub-secondary pages in the secondary pages is lower, and so on. Or orderly loading according to the data size of the PNG pictures.
In addition, in order to further improve the preloading efficiency, only the unloaded PNG pictures are subjected to the preloading operation, that is, when the small-memory embedded device is powered on, the unloaded PNG pictures are selected from all the PNG pictures to obtain all the unloaded PNG pictures, and the preloading operation is performed on all the unloaded PNG pictures to obtain the palette data and the compressed picture pixel data corresponding to all the unloaded PNG pictures, and the palette data and the compressed picture pixel data are stored.
S2, when the small-memory embedded device enters a display program, namely an interaction link is entered, according to a first PNG picture to be displayed, acquiring first palette data corresponding to the first PNG picture and compressed first picture pixel data; wherein, the first PNG picture to be displayed is known according to the display program.

In this scenario, the inventors have also tested the following three approaches:
the first method is as follows: and after the PNG picture is loaded, directly caching the PNG picture in a memory. When the display is needed, the display can be directly performed, and the PNG display speed is fastest in the mode. But occupies the largest memory, and is not suitable for a small-memory embedded system.
The second method comprises the following steps: after the PNG picture is loaded, the PNG picture is compressed and loaded to obtain picture pixel data, and the compressed data is cached in a memory. This approach takes up much less memory than the first approach. However, the size of the PNG picture in the project obtained by the secondary development of the user cannot be estimated, the pixel data compression effect of part of the PNG picture is not good, the problem of large memory occupation is likely to occur, and the result cannot be estimated, so that the method is not adopted.
The third method comprises the following steps: after the PNG picture is loaded, the pixel data of the picture is directly stored in the FLASH without being compressed, and the method can avoid the step of decompression after the PNG picture is read into the memory. However, the uncompressed pixel data is often larger, and the reading speed of FLASH is slow, so although the decompression step after reading the memory is saved, a longer time is spent in reading the uncompressed pixel data file, and the compressed pixel data is not as good as the compressed pixel data.
